# @posthog/browser-common
Internal shared browser utilities and extension primitives for PostHog JavaScript
SDKs. This package is published so unbundled SDK outputs can resolve it at
runtime, but it is not a public API surface and does not provide compatibility
guarantees outside PostHog SDK packages.
The shared extension contract includes the interface an extension implements
(`Extension`), the host adapter it receives (`Client`), and small shared runtime
primitives such as `Publisher`.
This contract is designed so an extension can run unchanged across major
versions of the web SDK. Concrete host adapters remain owned by their SDK
packages; browser-v1 and browser-v2 composition and loading integration are
separate from this shared runtime.
## Concepts
### `Extension`
What you implement. The host calls `setup` once and optional `dispose` for final cleanup:
```ts
import type { Disposable, Extension } from '@posthog/browser-common'
export function webContext(): Extension {
let removeProperties: Disposable | undefined
return {
name: 'webContext',
setup(client) {
removeProperties = client.registerDynamicEventProperties(() => ({
$current_url: window.location.href,
}))
},
dispose() {
removeProperties?.dispose()
},
}
}
```
`setup(client)` may be async to read state before the extension is ready. Async
extensions must guard work after each `await` so cleanup cannot be followed by
late listener or timer installation. `dispose()` is synchronous, optional,
idempotent, and best-effort. Static app config goes in the constructor, not on
`Client`.
Anything in `setup` that returns a `Disposable` must be held by the extension
and disposed in `dispose()`. Use `createDisposable(teardown)` when adapting a
synchronous callback into idempotent teardown.
### `Client`
What an extension is given in `setup` — the adapter shared by extensions on that host SDK instance:
- **identity and session**: `distinctId`, `anonymousId`, `deviceId`, `groups`, `session`, `initialPersonProperties`
- **SDK metadata**: `library`
- **capture permission**: `canCapture`
- **events**: `capture(...)`, `registerDynamicEventProperties(...)`, `onEvent(...)`
- **extensions**: `getExtension(token)`
- **server config**: `onRemoteConfig(...)`
- **transport**: `projectToken`, `sendRequest(path, init?)`, including `compression` and `sentAt` options
- **storage and logging**: `kv`, `logger`
Identity, session, SDK metadata, capture permission, and the public project token are always-ready synchronous reads.
`capture` synchronously admits an event to the host pipeline; use host lifecycle APIs when delivery completion matters.
`sendRequest` is awaitable. Its `sentAt` option controls `sent_at` placement on POST requests; GET query mode
uses the cache-busting `_` parameter instead, and GET body mode has no effect. `onRemoteConfig` replays the latest
available success or failure and then reports subsequent outcomes. Configuration timing is host-owned, and the
subscription remains active until disposed. Extensions that want a named log prefix can create a child with
`client.logger.createLogger('[myExtension]')`.
Extensions that expose controls to other extensions should export a typed stable-name token:
```ts
import type { Extension, ExtensionToken } from '@posthog/browser-common'
export interface DiagnosticsExtension extends Extension {
flush(): void
}
export const DiagnosticsExtension = 'diagnostics' as ExtensionToken<DiagnosticsExtension>
const diagnostics = client.getExtension(DiagnosticsExtension)
diagnostics?.flush()
```
Tokens are strings at runtime and must match the installed extension's `Extension.name`. Lookup is per-client and optional; a
returned extension may still be running `setup`, so consumers must not create mandatory startup cycles.
Initialize KV during asynchronous setup before using its synchronous buffer:
```ts
await client.kv.initialize()
const state = client.kv.get<{ first: boolean; second: string }>(['first', 'second'])
client.kv.set({ ...state, first: true })
client.kv.remove(['first', 'second'])
```
Initialization is idempotent and may be asynchronous while a host hydrates its buffer. After it completes, reads,
writes, and removals are synchronous; batch reads, object writes, and multi-key removals operate on related values
coherently. The host owns ordered durable flushing.
KV keys map directly to shared host persistence: reset clears them, collisions can overwrite host state, and unknown
keys may be captured as event properties. Use stable extension-owned keys with an explicit exposure policy, and do not
store sensitive values unless their transmission is approved.
### Host runtime
PostHog browser SDK implementations share extension registration and teardown
through `ExtensionRuntime`, imported from the dedicated
`@posthog/browser-common/extension-runtime` subpath. It reserves extension names
during setup, exposes registered extensions by typed stable name through `Client`,
rolls back failed setup, and disposes extensions once in reverse registration
order without waiting for pending setup. Concrete SDKs still own their `Client`
adapter and SDK lifecycle hooks.
`ExtensionRuntime` is host infrastructure, not part of the extension-author
surface exported from the package root.
### `Publisher`
Use `Publisher<T>` when an extension exposes an event stream. Keep the publisher
private, expose only its listener, and dispose it with the extension:
```ts
import { Publisher, type Listener } from '@posthog/browser-common/pubsub'
const changes = new Publisher<{ enabled: boolean }>()
export const onChange: Listener<{ enabled: boolean }> = changes.listener
changes.publish({ enabled: true })
changes.dispose()
```
## Utilities
Reusable browser utilities are exposed through `utils/*` subpaths, but they are
intentionally not re-exported from the package root or a utility barrel. Import
the exact file needed so lazy extension bundles do not pull in unrelated helpers:
```ts
import { createLogger } from '@posthog/browser-common/utils/logger'
import { formDataToQuery } from '@posthog/browser-common/utils/request-utils'
```
## Authoring
See the **`develop-extension`** skill
([`.agents/skills/develop-extension/SKILL.md`](./.agents/skills/develop-extension/SKILL.md))
for the complete authoring and browser-v1 porting guide.
## Status
Early and internal. The package currently defines the extension and client
contracts, a shared host runtime, lifecycle helpers, and directly imported
browser utilities under `utils/*` subpaths.@posthog/core@1.61.0 ・ MIT（posthog-js に取り込まれて配信）

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses

or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

## Requirements
- **Node.js 20 or later** (Node.js 18 support dropped as of October 31, 2025)
- For browser support, all modern browsers are supported
> ⚠️ **Node.js 18 Deprecation Notice**
>
> Node.js 18 reached end-of-life on April 30, 2025. As announced in [our deprecation notice](https://github.com/orgs/supabase/discussions/37217), support for Node.js 18 was dropped on October 31, 2025.
## Quick Start
### Installation
```bash
npm install @supabase/functions-js
```
### Usage
```js
import { FunctionsClient } from '@supabase/functions-js'
const functionsUrl = 'https://<project_ref>.supabase.co/functions/v1'
const anonKey = '<anon_key>'
const functions = new FunctionsClient(functionsUrl, {
headers: {
Authorization: `Bearer ${anonKey}`,
},
})
// Invoke a function
const { data, error } = await functions.invoke('hello-world', {
body: { name: 'Functions' },
})
```
## Development
This package is part of the [Supabase JavaScript monorepo](https://github.com/supabase/supabase-js). To work on this package:
### Building
```bash
# Complete build (from monorepo root)
npx nx build functions-js
# Build with watch mode for development
npx nx build functions-js --watch
# Individual build targets
npx nx build:main functions-js # CommonJS build (dist/main/)
npx nx build:module functions-js # ES Modules build (dist/module/)
# Other useful commands
npx nx clean functions-js # Clean build artifacts
npx nx typecheck functions-js # TypeScript type checking
npx nx docs functions-js # Generate documentation
```
#### Build Outputs
- **CommonJS (`dist/main/`)** - For Node.js environments
- **ES Modules (`dist/module/`)** - For modern bundlers (Webpack, Vite, Rollup)
- **TypeScript definitions (`dist/module/index.d.ts`)** - Type definitions for TypeScript projects
### Testing
**Docker Required** for relay tests. The functions-js tests use testcontainers to spin up a Deno relay server for testing Edge Function invocations.
```bash
# Run all tests (from monorepo root)
npx nx test functions-js
# Run tests with coverage report
npx nx test functions-js --coverage
# Run tests in watch mode during development
npx nx test functions-js --watch
# CI test command (runs with coverage)
npx nx test:ci functions-js
```
#### Test Requirements
- **Node.js 20+** - Required for testcontainers
- **Docker** - Must be installed and running for relay tests
- No Supabase instance needed - Tests use mocked services and testcontainers
#### What Gets Tested
- **Function invocation** - Testing the `invoke()` method with various options
- **Relay functionality** - Using a containerized Deno relay to test real Edge Function scenarios
- **Error handling** - Ensuring proper error responses and retries
- **Request/response models** - Validating headers, body, and response formats
### Contributing
We welcome contributions! Please see our [Contributing Guide](../../../CONTRIBUTING.md) for details on how to get started.
For major changes or if you're unsure about something, please open an issue first to discuss your proposed changes.@supabase/phoenix@0.4.0 ・ MIT

### Quick start
Install
```bash
npm install @supabase/postgrest-js
```
Usage
```js
import { PostgrestClient } from '@supabase/postgrest-js'
const REST_URL = 'http://localhost:3000'
const postgrest = new PostgrestClient(REST_URL)
```
- [select()](https://supabase.com/docs/reference/javascript/select)
- [insert()](https://supabase.com/docs/reference/javascript/insert)
- [update()](https://supabase.com/docs/reference/javascript/update)
- [delete()](https://supabase.com/docs/reference/javascript/delete)
#### Custom `fetch` implementation
`postgrest-js` uses the [`cross-fetch`](https://www.npmjs.com/package/cross-fetch) library to make HTTP requests, but an alternative `fetch` implementation can be provided as an option. This is most useful in environments where `cross-fetch` is not compatible, for instance Cloudflare Workers:
```js
import { PostgrestClient } from '@supabase/postgrest-js'
const REST_URL = 'http://localhost:3000'
const postgrest = new PostgrestClient(REST_URL, {
fetch: (...args) => fetch(...args),
})
```
## Development
This package is part of the [Supabase JavaScript monorepo](https://github.com/supabase/supabase-js). To work on this package:
### Building
```bash
# Build (from monorepo root)
npx nx build postgrest-js
# Build with watch mode for development
npx nx build:watch postgrest-js
# TypeScript type checking
npx nx type-check postgrest-js
# Generate documentation
npx nx docs postgrest-js
```
### Testing
**Supabase CLI Required!** The `postgrest-js` tests use the [Supabase CLI](https://supabase.com/docs/guides/local-development/cli/getting-started) to run a local PostgreSQL database and PostgREST server.
#### Quick Start
```bash
# Run all tests (from monorepo root)
npx nx test:ci:postgrest postgrest-js
```
This single command automatically:
1. Stops any existing Supabase CLI containers
2. Starts PostgreSQL database and PostgREST server via Supabase CLI
3. Resets and seeds the database
4. Runs all Jest unit tests with coverage
5. Cleans up containers
#### Individual Test Commands
```bash
# Run Jest tests with coverage (requires infrastructure running)
npx nx test:run postgrest-js
# Run type tests with tstyche
npx nx test:types postgrest-js
# Run smoke tests (CommonJS and ESM imports)
npx nx test:smoke postgrest-js
# Format code
npx nx format postgrest-js
# Check formatting
npx nx format:check postgrest-js
```
#### Test Infrastructure
The tests use Supabase CLI to spin up:
- **PostgreSQL** - Database with test schema and seed data (port 54322)
- **PostgREST** - REST API server that the client connects to (port 54321)
```bash
# Manually manage test infrastructure (from monorepo root)
npx nx test:infra postgrest-js # Start containers
npx nx test:clean-pre postgrest-js # Stop and remove containers
```
Or directly via Supabase CLI:
```bash
cd packages/core/postgrest-js
npx supabase --workdir ./test start # Start all services
npx supabase --workdir ./test db reset # Reset and seed database
npx supabase --workdir ./test stop # Stop all services
```
#### Regenerating TypeScript Types
When the database schema changes, regenerate TypeScript types from the actual database:
```bash
# From the monorepo root
npm run codegen:postgrest
```
This command automatically:
1. Cleans up any existing Supabase containers
2. Starts Supabase (PostgreSQL, PostgREST, and all services)
3. Generates TypeScript types from the database schema
4. Post-processes the generated types (updates JSON type definitions)
5. Formats the generated file with Prettier
6. Cleans up Supabase containers
The generated types are written to `test/types.generated.ts`.
#### Test Types Explained
- **Unit Tests** - Jest tests covering all client functionality (`npx nx test:run postgrest-js`)
- **Type Tests** - Validates TypeScript types using tstyche (`npx nx test:types postgrest-js`)
- **Smoke Tests** - Basic import/require tests for CommonJS and ESM (`npx nx test:smoke postgrest-js`)
#### Prerequisites
- **Supabase CLI** must be installed ([instructions](https://supabase.com/docs/guides/local-development/cli/getting-started)) or can be used through `npx` (`npx supabase`)
- **Docker** must be installed and running (Supabase CLI uses Docker under the hood)
- **Port 54321** - PostgREST API
- **Port 54322** - PostgreSQL database
- **Port 54323** - Supabase Studio (used for type generation)
#### PostgREST v12 Backward Compatibility Tests
We maintain backward compatibility tests for PostgREST v12 (the current Supabase CLI uses v14+). These tests ensure the SDK works correctly for users still running older PostgREST versions.
```bash
# Run v12 compatibility tests (requires Docker)
npx nx test:ci:v12 postgrest-js
```
This command:
1. Starts PostgREST v12 + PostgreSQL in Docker (ports 3012/5433)
2. Runs runtime tests that verify v12-specific behavior
3. Cleans up containers
**Type-only tests** for v12 compatibility also run as part of the regular type tests:
```bash
npx nx test:types postgrest-js # Includes v12-compat.test-d.ts
```
**Note:** These v12 tests will be removed when v3 ships (sometime in 2026).

# Overview
This SDK enables you to use the following Supabase Realtime's features:
- **Broadcast**: send ephemeral messages from client to clients with minimal latency. Use cases include sharing cursor positions between users.
- **Presence**: track and synchronize shared state across clients with the help of CRDTs. Use cases include tracking which users are currently viewing a specific webpage.
- **Postgres Change Data Capture (CDC)**: listen for changes in your PostgreSQL database and send them to clients.
# Usage
## Installing the Package
```bash
npm install @supabase/realtime-js
```
## Creating a Channel
```js
import { RealtimeClient } from '@supabase/realtime-js'
const client = new RealtimeClient(REALTIME_URL, {
params: {
apikey: API_KEY,
},
})
const channel = client.channel('test-channel', {})
channel.subscribe((status, err) => {
if (status === 'SUBSCRIBED') {
console.log('Connected!')
}
if (status === 'CHANNEL_ERROR') {
console.log(`There was an error subscribing to channel: ${err.message}`)
}
if (status === 'TIMED_OUT') {
console.log('Realtime server did not respond in time.')
}
if (status === 'CLOSED') {
console.log('Realtime channel was unexpectedly closed.')
}
})
```
### Notes:
- `REALTIME_URL` is `'ws://localhost:4000/socket'` when developing locally and `'wss://<project_ref>.supabase.co/realtime/v1'` when connecting to your Supabase project.
- `API_KEY` is a JWT whose claims must contain `exp` and `role` (existing database role).
- Channel name can be any `string`.
- Setting `private` to `true` means that the client will use RLS to determine if the user can connect or not to a given channel.
## Broadcast
Your client can send and receive messages based on the `event`.
```js
// Setup...
const channel = client.channel('broadcast-test', { broadcast: { ack: false, self: false } })
channel.on('broadcast', { event: 'some-event' }, (payload) => console.log(payload))
channel.subscribe(async (status) => {
if (status === 'SUBSCRIBED') {
// Send message to other clients listening to 'broadcast-test' channel
await channel.send({
type: 'broadcast',
event: 'some-event',
payload: { hello: 'world' },
})
}
})
```
### Notes:
- Setting `ack` to `true` means that the `channel.send` promise will resolve once server replies with acknowledgment that it received the broadcast message request.
- Setting `self` to `true` means that the client will receive the broadcast message it sent out.
### Broadcast Replay
Broadcast Replay enables **private** channels to access messages that were sent earlier. Only messages published via [Broadcast From the Database](https://supabase.com/docs/guides/realtime/broadcast#trigger-broadcast-messages-from-your-database) are available for replay.
You can configure replay with the following options:
- **`since`** (Required): The epoch timestamp in milliseconds, specifying the earliest point from which messages should be retrieved.
- **`limit`** (Optional): The number of messages to return. This must be a positive integer, with a maximum value of 25.
Example:
```typescript
const twelveHours = 12 * 60 * 60 * 1000
const twelveHoursAgo = Date.now() - twelveHours
const config = { private: true, broadcast: { replay: { since: twelveHoursAgo, limit: 10 } } }
supabase
.channel('main:room', { config })
.on('broadcast', { event: 'my_event' }, (payload) => {
if (payload?.meta?.replayed) {
console.log('This message was sent earlier:', payload)
} else {
console.log('This is a new message', payload)
}
// ...
})
.subscribe()
```
## Presence
Your client can track and sync state that's stored in the channel.
```js
// Setup...
const channel = client.channel('presence-test', {
config: {
presence: {
key: '',
},
},
})
channel.on('presence', { event: 'sync' }, () => {
console.log('Online users: ', channel.presenceState())
})
channel.on('presence', { event: 'join' }, ({ newPresences }) => {
console.log('New users have joined: ', newPresences)
})
channel.on('presence', { event: 'leave' }, ({ leftPresences }) => {
console.log('Users have left: ', leftPresences)
})
channel.subscribe(async (status) => {
if (status === 'SUBSCRIBED') {
const status = await channel.track({ user_id: 1 })
console.log(status)
}
})
```
## Postgres CDC
Receive database changes on the client.
```js
// Setup...
const channel = client.channel('db-changes')
channel.on('postgres_changes', { event: '*', schema: 'public' }, (payload) => {
console.log('All changes in public schema: ', payload)
})
channel.on(
'postgres_changes',
{ event: 'INSERT', schema: 'public', table: 'messages' },
(payload) => {
console.log('All inserts in messages table: ', payload)
}
)
channel.on(
'postgres_changes',
{ event: 'UPDATE', schema: 'public', table: 'users', filter: 'username=eq.Realtime' },
(payload) => {
console.log('All updates on users table when username is Realtime: ', payload)
}
)
channel.subscribe(async (status) => {
if (status === 'SUBSCRIBED') {
console.log('Ready to receive database changes!')
}
})
```
## Get All Channels
You can see all the channels that your client has instantiatied.
```js
// Setup...
client.getChannels()
```
## Cleanup
It is highly recommended that you clean up your channels after you're done with them.
- Remove a single channel
```js
// Setup...
const channel = client.channel('some-channel-to-remove')
channel.unsubscribe()
client.removeChannel(channel)
```
- Remove all channels and close the connection
```js
// Setup...
client.removeAllChannels()
client.disconnect()
```
## Development
This package is part of the [Supabase JavaScript monorepo](https://github.com/supabase/supabase-js). To work on this package:
### Building
```bash
# Complete build (from monorepo root)
npx nx build realtime-js
# Build with watch mode for development
npx nx build realtime-js --watch
# Individual build targets
npx nx build:main realtime-js # CommonJS build (dist/main/)
npx nx build:module realtime-js # ES Modules build (dist/module/)
# Other useful commands
npx nx clean realtime-js # Clean build artifacts
npx nx lint realtime-js # Run ESLint
npx nx typecheck realtime-js # TypeScript type checking
```
#### Build Outputs
- **CommonJS (`dist/main/`)** - For Node.js environments
- **ES Modules (`dist/module/`)** - For modern bundlers (Webpack, Vite, Rollup)
- **TypeScript definitions (`dist/module/index.d.ts`)** - Type definitions for TypeScript projects
Note: Unlike some other packages, realtime-js doesn't include a UMD build since it's primarily used in Node.js or bundled applications.
#### Validating Package Exports
```bash
# Check if package exports are correctly configured
npx nx check-exports realtime-js
```
This command uses ["Are the types wrong?"](https://github.com/arethetypeswrong/arethetypeswrong.github.io) to verify that the package exports work correctly in different environments. Run this before publishing to ensure your package can be imported correctly by all consumers.
### Testing
**No Docker or Supabase instance required!** The realtime-js tests use mocked WebSocket connections, so they're completely self-contained.
```bash
# Run unit tests (from monorepo root)
npx nx test realtime-js
# Run tests with coverage report
npx nx test:coverage realtime-js
# Run tests in watch mode during development
npx nx test:watch realtime-js
```
#### Test Scripts Explained
- **test** - Runs all unit tests once using Vitest
- **test:coverage** - Runs tests and generates coverage report with terminal output
- **test:watch** - Runs tests in interactive watch mode for development
The tests mock WebSocket connections using `mock-socket`, so you can run them anytime without any external dependencies.

> Node.js 18 reached end-of-life on April 30, 2025. As announced in [our deprecation notice](https://github.com/orgs/supabase/discussions/37217), support for Node.js 18 was dropped on October 31, 2025.
## Features
- **File Storage**: Upload, download, list, move, and delete files
- **Access Control**: Public and private buckets with fine-grained permissions
- **Signed URLs**: Generate time-limited URLs for secure file access
- **Image Transformations**: On-the-fly image resizing and optimization
- **Vector Embeddings**: Store and query high-dimensional embeddings with similarity search
- **Analytics Buckets**: Iceberg table-based buckets optimized for analytical queries and data processing
## Quick Start Guide
### Installing the module
```bash
npm install @supabase/storage-js
```
### Connecting to the storage backend
There are two ways to use the Storage SDK:
#### Option 1: Via Supabase Client (Recommended)
If you're already using `@supabase/supabase-js`, access storage through the client:
```js
import { createClient } from '@supabase/supabase-js'
// Use publishable/anon key for frontend applications
const supabase = createClient('https://<project_ref>.supabase.co', '<your-publishable-key>')
// Access storage
const storage = supabase.storage
// Access different bucket types
const regularBucket = storage.from('my-bucket')
const vectorBucket = storage.vectors.from('embeddings-bucket')
const analyticsBucket = storage.analytics // Analytics API
```
#### Option 2: Standalone StorageClient
For backend applications or when you need to bypass Row Level Security:
```js
import { StorageClient } from '@supabase/storage-js'
const STORAGE_URL = 'https://<project_ref>.supabase.co/storage/v1'
const SERVICE_KEY = '<your-secret-key>' // Use secret key for backend operations
const storageClient = new StorageClient(STORAGE_URL, {
apikey: SERVICE_KEY,
Authorization: `Bearer ${SERVICE_KEY}`,
})
// Access different bucket types
const regularBucket = storageClient.from('my-bucket')
const vectorBucket = storageClient.vectors.from('embeddings-bucket')
const analyticsBucket = storageClient.analytics // Analytics API
```
> **When to use each approach:**
>
> - Use `supabase.storage` when working with other Supabase features (auth, database, etc.) in frontend applications
> - Use `new StorageClient()` for backend applications, Edge Functions, or when you need to bypass RLS policies
> **Note:** Refer to the [Storage Access Control guide](https://supabase.com/docs/guides/storage/access-control) for detailed information on creating RLS policies.
### Understanding Bucket Types
Supabase Storage supports three types of buckets, each optimized for different use cases:
#### 1. Regular Storage Buckets (File Storage)
Standard buckets for storing files, images, videos, and other assets.
```js
// Create regular storage bucket
const { data, error } = await storageClient.createBucket('my-files', {
public: false,
})
// Upload files
await storageClient.from('my-files').upload('avatar.png', file)
```
**Use cases:** User uploads, media assets, documents, backups
#### 2. Vector Buckets (Embeddings Storage)
Specialized buckets for storing and querying high-dimensional vector embeddings.
```js
// Create vector bucket
await storageClient.vectors.createBucket('embeddings-prod')
// Create index and insert vectors
const bucket = storageClient.vectors.from('embeddings-prod')
await bucket.createIndex({
indexName: 'documents',
dimension: 1536,
distanceMetric: 'cosine',
})
```
**Use cases:** Semantic search, AI-powered recommendations, similarity matching
**[See full Vector Embeddings documentation below](#vector-embeddings)**
#### 3. Analytics Buckets
Specialized buckets using Apache Iceberg table format, optimized for analytical queries and large-scale data processing.
```js
// Create analytics bucket
await storageClient.analytics.createBucket('analytics-data')
// List analytics buckets
const { data, error } = await storageClient.analytics.listBuckets()
// Delete analytics bucket
await storageClient.analytics.deleteBucket('analytics-data')
```
**Use cases:** Time-series data, analytical queries, data lakes, large-scale data processing, business intelligence
**[See full Analytics Buckets documentation below](#analytics-buckets)**
---
### Handling resources
#### Handling Storage Buckets
- Create a new Storage bucket:
```js
const { data, error } = await storageClient.createBucket(
'test_bucket', // Bucket name (must be unique)
{ public: false } // Bucket options
)
```
- Retrieve the details of an existing Storage bucket:
```js
const { data, error } = await storageClient.getBucket('test_bucket')
```
- Update a new Storage bucket:
```js
const { data, error } = await storageClient.updateBucket(
'test_bucket', // Bucket name
{ public: false } // Bucket options
)
```
- Remove all objects inside a single bucket:
```js
const { data, error } = await storageClient.emptyBucket('test_bucket')
```
- Delete an existing bucket (a bucket can't be deleted with existing objects inside it):
```js
const { data, error } = await storageClient.deleteBucket('test_bucket')
```
- Retrieve the details of all Storage buckets within an existing project:
```js
// List all buckets
const { data, error } = await storageClient.listBuckets()
// List buckets with options (pagination, sorting, search)
const { data, error } = await storageClient.listBuckets({
limit: 10,
offset: 0,
sortColumn: 'created_at',
sortOrder: 'desc',
search: 'prod',
})
```
#### Handling Files
- Upload a file to an existing bucket:
```js
const fileBody = ... // load your file here
const { data, error } = await storageClient.from('bucket').upload('path/to/file', fileBody)
```
> Note:
> The path in `data.Key` is prefixed by the bucket ID and is not the value which should be passed to the `download` method in order to fetch the file.
> To fetch the file via the `download` method, use `data.path` and `data.bucketId` as follows:
>
> ```javascript
> const { data, error } = await storageClient.from('bucket').upload('/folder/file.txt', fileBody)
> // check for errors
> const { data2, error2 } = await storageClient.from(data.bucketId).download(data.path)
> ```
> Note: The `upload` method also accepts a map of optional parameters. For a complete list see the [Supabase API reference](https://supabase.com/docs/reference/javascript/storage-from-upload).
- Download a file from an exisiting bucket:
```js
const { data, error } = await storageClient.from('bucket').download('path/to/file')
```
- List all the files within a bucket:
```js
const { data, error } = await storageClient.from('bucket').list('folder')
```
> Note: The `list` method also accepts a map of optional parameters. For a complete list see the [Supabase API reference](https://supabase.com/docs/reference/javascript/storage-from-list).
- Replace an existing file at the specified path with a new one:
```js
const fileBody = ... // load your file here
const { data, error } = await storageClient
.from('bucket')
.update('path/to/file', fileBody)
```
> Note: The `upload` method also accepts a map of optional parameters. For a complete list see the [Supabase API reference](https://supabase.com/docs/reference/javascript/storage-from-upload).
- Move an existing file:
```js
const { data, error } = await storageClient
.from('bucket')
.move('old/path/to/file', 'new/path/to/file')
```
- Delete files within the same bucket:
```js
const { data, error } = await storageClient.from('bucket').remove(['path/to/file'])
```
- Create signed URL to download file without requiring permissions:
```js
const expireIn = 60
const { data, error } = await storageClient
.from('bucket')
.createSignedUrl('path/to/file', expireIn)
```
- Retrieve URLs for assets in public buckets:
```js
const { data, error } = await storageClient.from('public-bucket').getPublicUrl('path/to/file')
```
## Analytics Buckets
Supabase Storage provides specialized analytics buckets using Apache Iceberg table format, optimized for analytical workloads and large-scale data processing. These buckets are designed for data lake architectures, time-series data, and business intelligence applications.
### What are Analytics Buckets?
Analytics buckets use the Apache Iceberg open table format, providing:
- **ACID transactions** for data consistency
- **Schema evolution** without data rewrites
- **Time travel** to query historical data
- **Efficient metadata management** for large datasets
- **Optimized for analytical queries** rather than individual file operations
### When to Use Analytics Buckets
**Use analytics buckets for:**
- Time-series data (logs, metrics, events)
- Data lake architectures
- Business intelligence and reporting
- Large-scale batch processing
- Analytical workloads requiring ACID guarantees
**Use regular storage buckets for:**
- User file uploads (images, documents, videos)
- Individual file management
- Content delivery
- Simple object storage needs
### Quick Start
You can access analytics functionality through the `analytics` property on your storage client:
#### Via Supabase Client
```typescript
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('https://your-project.supabase.co', 'your-publishable-key')
// Access analytics operations
const analytics = supabase.storage.analytics
// Create an analytics bucket
const { data, error } = await analytics.createBucket('analytics-data')
if (error) {
console.error('Failed to create analytics bucket:', error.message)
} else {
console.log('Created bucket:', data.name)
}
```
#### Via StorageClient
```typescript
import { StorageClient } from '@supabase/storage-js'
const storageClient = new StorageClient('https://your-project.supabase.co/storage/v1', {
apikey: 'YOUR_API_KEY',
Authorization: 'Bearer YOUR_TOKEN',
})
// Access analytics operations
const analytics = storageClient.analytics
// Create an analytics bucket
await analytics.createBucket('analytics-data')
```
### API Reference
#### Create Analytics Bucket
Creates a new analytics bucket using Iceberg table format:
```typescript
const { data, error } = await analytics.createBucket('my-analytics-bucket')
if (error) {
console.error('Error:', error.message)
} else {
console.log('Created bucket:', data)
}
```
**Returns:**
```typescript
{
data: {
id: string
type: 'ANALYTICS'
format: string
created_at: string
updated_at: string
} | null
error: StorageError | null
}
```
#### List Analytics Buckets
Retrieves all analytics buckets in your project with optional filtering and pagination:
```typescript
const { data, error } = await analytics.listBuckets({
limit: 10,
offset: 0,
sortColumn: 'created_at',
sortOrder: 'desc',
search: 'prod',
})
if (data) {
console.log(`Found ${data.length} analytics buckets`)
data.forEach((bucket) => {
console.log(`- ${bucket.id} (created: ${bucket.created_at})`)
})
}
```
**Parameters:**
- `limit?: number` - Maximum number of buckets to return
- `offset?: number` - Number of buckets to skip (for pagination)
- `sortColumn?: 'id' | 'name' | 'created_at' | 'updated_at'` - Column to sort by
- `sortOrder?: 'asc' | 'desc'` - Sort direction
- `search?: string` - Search term to filter bucket names
**Returns:**
```typescript
{
data: AnalyticBucket[] | null
error: StorageError | null
}
```
**Example with Pagination:**
```typescript
// Fetch first page
const firstPage = await analytics.listBuckets({
limit: 100,
offset: 0,
sortColumn: 'created_at',
sortOrder: 'desc',
})
// Fetch second page
const secondPage = await analytics.listBuckets({
limit: 100,
offset: 100,
sortColumn: 'created_at',
sortOrder: 'desc',
})
```
#### Delete Analytics Bucket
Deletes an analytics bucket. The bucket must be empty before deletion.
```typescript
const { data, error } = await analytics.deleteBucket('old-analytics-bucket')
if (error) {
console.error('Failed to delete:', error.message)
} else {
console.log('Bucket deleted:', data.message)
}
```
**Returns:**
```typescript
{
data: { message: string } | null
error: StorageError | null
}
```
> **Note:** A bucket cannot be deleted if it contains data. You must empty the bucket first.
#### Get Iceberg Catalog for Advanced Operations
For advanced operations like creating tables, namespaces, and querying Iceberg metadata, use the `from()` method to get a configured [iceberg-js](https://github.com/supabase/iceberg-js) client:
```typescript
// Get an Iceberg REST Catalog client for your analytics bucket
const catalog = analytics.from('analytics-data')
// Create a namespace
await catalog.createNamespace({ namespace: ['default'] }, { properties: { owner: 'data-team' } })
// Create a table with schema
await catalog.createTable(
{ namespace: ['default'] },
{
name: 'events',
schema: {
type: 'struct',
fields: [
{ id: 1, name: 'id', type: 'long', required: true },
{ id: 2, name: 'timestamp', type: 'timestamp', required: true },
{ id: 3, name: 'user_id', type: 'string', required: false },
],
'schema-id': 0,
'identifier-field-ids': [1],
},
'partition-spec': {
'spec-id': 0,
fields: [],
},
'write-order': {
'order-id': 0,
fields: [],
},
properties: {
'write.format.default': 'parquet',
},
}
)
// List tables in namespace
const tables = await catalog.listTables({ namespace: ['default'] })
console.log(tables) // [{ namespace: ['default'], name: 'events' }]
// Load table metadata
const table = await catalog.loadTable({ namespace: ['default'], name: 'events' })
// Update table properties
await catalog.updateTable(
{ namespace: ['default'], name: 'events' },
{ properties: { 'read.split.target-size': '134217728' } }
)
// Drop table
await catalog.dropTable({ namespace: ['default'], name: 'events' })
// Drop namespace
await catalog.dropNamespace({ namespace: ['default'] })
```
**Returns:** `IcebergRestCatalog` instance from [iceberg-js](https://github.com/supabase/iceberg-js)
> **Note:** The `from()` method returns an Iceberg REST Catalog client that provides full access to the Apache Iceberg REST API. For complete documentation of available operations, see the [iceberg-js documentation](https://supabase.github.io/iceberg-js/).
### Error Handling
Analytics buckets use the same error handling pattern as the rest of the Storage SDK:
```typescript
const { data, error } = await analytics.createBucket('my-bucket')
if (error) {
console.error('Error:', error.message)
console.error('Status:', error.status)
console.error('Status Code:', error.statusCode)
// Handle error appropriately
}
```
#### Throwing Errors
You can configure the client to throw errors instead of returning them:
```typescript
const analytics = storageClient.analytics
analytics.throwOnError()
try {
const { data } = await analytics.createBucket('my-bucket')
// data is guaranteed to be present
console.log('Success:', data)
} catch (error) {
if (error instanceof StorageApiError) {
console.error('API Error:', error.statusCode, error.message)
}
}
```
### TypeScript Types
The library exports TypeScript types for analytics buckets:
```typescript
import type { AnalyticBucket, BucketType, StorageError } from '@supabase/storage-js'
// AnalyticBucket type
interface AnalyticBucket {
id: string
type: 'ANALYTICS'
format: string
created_at: string
updated_at: string
}
```
### Common Patterns
#### Checking if a Bucket Exists
```typescript
async function bucketExists(bucketName: string): Promise<boolean> {
const { data, error } = await analytics.listBuckets({
search: bucketName,
})
if (error) {
console.error('Error checking bucket:', error.message)
return false
}
return data?.some((bucket) => bucket.id === bucketName) ?? false
}
```
#### Creating Bucket with Error Handling
```typescript
async function ensureAnalyticsBucket(bucketName: string) {
// Try to create the bucket
const { data, error } = await analytics.createBucket(bucketName)
if (error) {
// Check if bucket already exists (conflict error)
if (error.statusCode === '409') {
console.log(`Bucket '${bucketName}' already exists`)
return { success: true, created: false }
}
// Other error occurred
console.error('Failed to create bucket:', error.message)
return { success: false, error }
}
console.log(`Created new bucket: '${bucketName}'`)
return { success: true, created: true, data }
}
```
#### Listing All Buckets with Pagination
```typescript
async function getAllAnalyticsBuckets() {
const allBuckets: AnalyticBucket[] = []
let offset = 0
const limit = 100
while (true) {
const { data, error } = await analytics.listBuckets({
limit,
offset,
sortColumn: 'created_at',
sortOrder: 'desc',
})
if (error) {
console.error('Error fetching buckets:', error.message)
break
}
if (!data || data.length === 0) {
break
}
allBuckets.push(...data)
// If we got fewer results than the limit, we've reached the end
if (data.length < limit) {
break
}
offset += limit
}
return allBuckets
}
```
## Vector Embeddings
Supabase Storage provides built-in support for storing and querying high-dimensional vector embeddings, powered by S3 Vectors. This enables semantic search, similarity matching, and AI-powered applications without needing a separate vector database.
> **Note:** Vector embeddings functionality is available in `@supabase/storage-js` v2.76 and later.
### Features
- **Vector Buckets**: Organize vector indexes into logical containers
- **Vector Indexes**: Define schemas with configurable dimensions and distance metrics
- **Batch Operations**: Insert/update/delete up to 500 vectors per request
- **Similarity Search**: Query for nearest neighbors using cosine, euclidean, or dot product distance
- **Metadata Filtering**: Store and filter vectors by arbitrary JSON metadata
- **Pagination**: Efficiently scan large vector datasets
- **Parallel Scanning**: Distribute scans across multiple workers for high throughput
- **Cross-platform**: Works in Node.js, browsers, and edge runtimes
### Quick Start
You can access vector functionality in three ways, depending on your use case:
#### Option 1: Via Supabase Client (Most Common)
If you're using the full Supabase client:
```typescript
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('https://your-project.supabase.co', 'your-publishable-key')
// Access vector operations through storage
const vectors = supabase.storage.vectors
// Create a vector bucket
await vectors.createBucket('embeddings-prod')
// Create an index
const bucket = vectors.from('embeddings-prod')
await bucket.createIndex({
indexName: 'documents-openai',
dataType: 'float32',
dimension: 1536,
distanceMetric: 'cosine',
})
// Insert vectors
const index = bucket.index('documents-openai')
await index.putVectors({
vectors: [
{
key: 'doc-1',
data: { float32: [0.1, 0.2, 0.3 /* ...1536 dimensions */] },
metadata: { title: 'Introduction', category: 'docs' },
},
],
})
// Query similar vectors
const { data, error } = await index.queryVectors({
queryVector: { float32: [0.15, 0.25, 0.35 /* ...1536 dimensions */] },
topK: 5,
returnDistance: true,
returnMetadata: true,
})
if (data) {
data.matches.forEach((match) => {
console.log(`${match.key}: distance=${match.distance}`)
console.log('Metadata:', match.metadata)
})
}
```
#### Option 2: Via StorageClient
If you're using the standalone `StorageClient` for storage operations, access vectors through the `vectors` property:
```typescript
import { StorageClient } from '@supabase/storage-js'
const storageClient = new StorageClient('https://your-project.supabase.co/storage/v1', {
apikey: 'YOUR_API_KEY',
Authorization: 'Bearer YOUR_TOKEN',
})
// Access vector operations
const vectors = storageClient.vectors
// Use the same API as shown in Option 1
await vectors.createBucket('embeddings-prod')
const bucket = vectors.from('embeddings-prod')
// ... rest of operations
```
#### Option 3: Standalone Vector Client
For vector-only applications that don't need regular file storage operations:
```typescript
import { StorageVectorsClient } from '@supabase/storage-js'
// Initialize standalone vector client
const vectorClient = new StorageVectorsClient('https://your-project.supabase.co/storage/v1', {
headers: { Authorization: 'Bearer YOUR_TOKEN' },
})
// Use the same API as shown in Option 1
await vectorClient.createBucket('embeddings-prod')
const bucket = vectorClient.from('embeddings-prod')
// ... rest of operations
```
> **When to use each approach:**
>
> - **Option 1**: When using other Supabase features (auth, database, realtime)
> - **Option 2**: When working with both file storage and vectors
> - **Option 3**: For dedicated vector-only applications without file storage
### API Reference
#### Client Initialization
```typescript
const vectorClient = new StorageVectorsClient(url, options?)
```
**Options:**
- `headers?: Record<string, string>` - Custom HTTP headers (e.g., Authorization)
- `fetch?: Fetch` - Custom fetch implementation
#### Vector Buckets
Vector buckets are top-level containers for organizing vector indexes.
##### Create Bucket
```typescript
const { data, error } = await vectorClient.createBucket('my-bucket')
```
##### Get Bucket
```typescript
const { data, error } = await vectorClient.getBucket('my-bucket')
console.log('Created at:', new Date(data.vectorBucket.creationTime! * 1000))
```
##### List Buckets
```typescript
const { data, error } = await vectorClient.listBuckets({
prefix: 'prod-',
maxResults: 100,
})
// Pagination
if (data?.nextToken) {
const next = await vectorClient.listBuckets({ nextToken: data.nextToken })
}
```
##### Delete Bucket
```typescript
// Bucket must be empty (all indexes deleted first)
const { error } = await vectorClient.deleteBucket('my-bucket')
```
#### Vector Indexes
Vector indexes define the schema for embeddings including dimension and distance metric.
##### Create Index
```typescript
const bucket = vectorClient.from('my-bucket')
await bucket.createIndex({
indexName: 'my-index',
dataType: 'float32',
dimension: 1536,
distanceMetric: 'cosine', // 'cosine' | 'euclidean' | 'dotproduct'
metadataConfiguration: {
nonFilterableMetadataKeys: ['raw_text', 'internal_id'],
},
})
```
**Distance Metrics:**
- `cosine` - Cosine similarity (normalized dot product)
- `euclidean` - Euclidean distance (L2 norm)
- `dotproduct` - Dot product similarity
##### Get Index
```typescript
const { data, error } = await bucket.getIndex('my-index')
console.log('Dimension:', data?.index.dimension)
console.log('Distance metric:', data?.index.distanceMetric)
```
##### List Indexes
```typescript
const { data, error } = await bucket.listIndexes({
prefix: 'documents-',
maxResults: 100,
})
```
##### Delete Index
```typescript
// Deletes index and all its vectors
await bucket.deleteIndex('my-index')
```
#### Vector Operations
##### Insert/Update Vectors (Upsert)
```typescript
const index = vectorClient.from('my-bucket').index('my-index')
await index.putVectors({
vectors: [
{
key: 'unique-id-1',
data: {
float32: [
/* 1536 numbers */
],
},
metadata: {
title: 'Document Title',
category: 'technical',
page: 1,
},
},
// ... up to 500 vectors per request
],
})
```
**Limitations:**
- 1-500 vectors per request
- Vectors must match index dimension
- Keys must be unique within index
##### Get Vectors by Key
```typescript
const { data, error } = await index.getVectors({
keys: ['doc-1', 'doc-2', 'doc-3'],
returnData: true, // Include embeddings
returnMetadata: true, // Include metadata
})
data?.vectors.forEach((v) => {
console.log(v.key, v.metadata)
})
```
##### Query Similar Vectors (ANN Search)
```typescript
const { data, error } = await index.queryVectors({
queryVector: {
float32: [
/* 1536 numbers */
],
},
topK: 10,
filter: {
category: 'technical',
published: true,
},
returnDistance: true,
returnMetadata: true,
})
// Results ordered by similarity
data?.matches.forEach((match) => {
console.log(`${match.key}: distance=${match.distance}`)
})
```
**Filter Syntax:**
The `filter` parameter accepts arbitrary JSON for metadata filtering. Non-filterable keys (configured at index creation) cannot be used in filters but can still be returned.
##### List/Scan Vectors
```typescript
// Simple pagination
let nextToken: string | undefined
do {
const { data } = await index.listVectors({
maxResults: 500,
nextToken,
returnMetadata: true,
})
console.log('Batch:', data?.vectors.length)
nextToken = data?.nextToken
} while (nextToken)
// Parallel scanning (4 workers)
const workers = [0, 1, 2, 3].map(async (segmentIndex) => {
const { data } = await index.listVectors({
segmentCount: 4,
segmentIndex,
returnMetadata: true,
})
return data?.vectors || []
})
const results = await Promise.all(workers)
const allVectors = results.flat()
```
**Limitations:**
- `maxResults`: 1-1000 (default: 500)
- `segmentCount`: 1-16
- Response may be limited by 1MB size
##### Delete Vectors
```typescript
await index.deleteVectors({
keys: ['doc-1', 'doc-2', 'doc-3'],
// ... up to 500 keys per request
})
```
### Error Handling
The library uses a consistent error handling pattern:
```typescript
const { data, error } = await vectorClient.createBucket('my-bucket')
if (error) {
console.error('Error:', error.message)
console.error('Status:', error.status)
console.error('Code:', error.statusCode)
}
```
#### Error Codes
| Code | HTTP | Description |
| ---------------------------- | ---- | ----------------------- |
| `InternalError` | 500 | Internal server error |
| `S3VectorConflictException` | 409 | Resource already exists |
| `S3VectorNotFoundException` | 404 | Resource not found |
| `S3VectorBucketNotEmpty` | 400 | Bucket contains indexes |
| `S3VectorMaxBucketsExceeded` | 400 | Bucket quota exceeded |
| `S3VectorMaxIndexesExceeded` | 400 | Index quota exceeded |
#### Throwing Errors
You can configure the client to throw errors instead:
```typescript
const vectorClient = new StorageVectorsClient(url, options)
vectorClient.throwOnError()
try {
const { data } = await vectorClient.createBucket('my-bucket')
// data is guaranteed to be present
} catch (error) {
if (error instanceof StorageVectorsApiError) {
console.error('API Error:', error.statusCode)
}
}
```
### Advanced Usage
#### Scoped Clients
Create scoped clients for cleaner code:
```typescript
// Bucket-scoped operations
const bucket = vectorClient.from('embeddings-prod')
await bucket.createIndex({
/* ... */
})
await bucket.listIndexes()
// Index-scoped operations
const index = bucket.index('documents-openai')
await index.putVectors({
/* ... */
})
await index.queryVectors({
/* ... */
})
```
#### Custom Fetch
Provide a custom fetch implementation:
```typescript
import { StorageVectorsClient } from '@supabase/storage-js'
const vectorClient = new StorageVectorsClient(url, {
fetch: customFetch,
headers: {
/* ... */
},
})
```
#### Batch Processing
Process large datasets in batches:
```typescript
async function insertLargeDataset(vectors: VectorObject[]) {
const batchSize = 500
for (let i = 0; i < vectors.length; i += batchSize) {
const batch = vectors.slice(i, i + batchSize)
await index.putVectors({ vectors: batch })
console.log(`Inserted ${i + batch.length}/${vectors.length}`)
}
}
```
#### Float32 Validation
Ensure vectors are properly normalized to float32:
```typescript
import { normalizeToFloat32 } from '@supabase/storage-js'
const vector = normalizeToFloat32([0.1, 0.2, 0.3 /* ... */])
```
### Type Definitions
The library exports comprehensive TypeScript types:
```typescript
import type {
VectorBucket,
VectorIndex,
VectorData,
VectorObject,
VectorMatch,
VectorMetadata,
DistanceMetric,
ApiResponse,
StorageVectorsError,
} from '@supabase/storage-js'
```
## Development
This package is part of the [Supabase JavaScript monorepo](https://github.com/supabase/supabase-js). To work on this package:
### Building
#### Build Scripts Overview
```bash
# Build the package
npx nx build storage-js
# Watch mode for development
npx nx build storage-js --watch
# Generate documentation
npx nx docs storage-js
```
### Testing
**Important:** The storage-js tests require a local Supabase stack running via the Supabase CLI. Docker must be running since the Supabase CLI uses it internally.
#### Prerequisites
1. **Docker** must be installed and running (used by Supabase CLI internally)
2. **Supabase CLI** — installed automatically via `npx supabase`
#### Test Scripts Overview
| Script | Description | What it does |
| ----------------- | --------------------------------- | ----------------------------------------------------------------- |
| `test:storage` | **Complete test workflow** | Runs the full test cycle: clean → start infra → run tests → clean |
| `test:suite` | **Jest tests only** | Runs Jest tests with coverage (requires infra to be running) |
| `test:infra` | **Start test infrastructure** | Starts Supabase CLI stack (PostgreSQL, Storage API, Kong, etc.) |
| `test:clean-post` | **Stop and clean infrastructure** | Stops the Supabase CLI stack |
#### Running Tests
##### Option 1: Complete Test Run (Recommended)
This handles everything automatically - starting infrastructure, running tests, and cleaning up:
```bash
# From monorepo root
npx nx test:storage storage-js
```
This command will:
1. Stop any existing test containers
2. Build and start fresh test infrastructure
3. Wait for services to be ready
4. Run all Jest tests with coverage
5. Clean up all containers after tests complete
##### Option 2: Manual Infrastructure Management
Useful for development when you want to run tests multiple times without restarting Docker:
```bash
# Step 1: Start the test infrastructure
# From root
npx nx test:infra storage-js
# This starts: PostgreSQL, Storage API, Kong Gateway, and imgproxy
# Step 2: Run tests (can run multiple times)
npx nx test:suite storage-js
# Step 3: When done, clean up the infrastructure
npx nx test:clean-post storage-js
```
##### Option 3: Development Mode
For actively developing and debugging tests:
```bash
# Start infrastructure once (from root)
npx nx test:infra storage-js
# Run tests in watch mode
npx nx test:suite storage-js --watch
# Clean up when done
npx nx test:clean-post storage-js
```
#### Test Infrastructure Details
The test infrastructure is managed via the Supabase CLI (`npx supabase start --workdir test`), which starts a local Supabase stack defined by the config in `test/`. This includes PostgreSQL, the Storage API, Kong Gateway, and supporting services.
#### Common Issues and Solutions
| Issue | Solution |
| --------------------------------- | ------------------------------------------------------------------------------------------------ |
| Port conflicts | Another service is using a required port. Run `npx nx test:clean-post storage-js` then try again |
| "request failed, reason:" errors | Infrastructure isn't running. Run `npx nx test:infra storage-js` first |
| Tests fail with connection errors | Ensure Docker is running (Supabase CLI requires Docker) |
| Stack already running | Run `npx nx test:clean-post storage-js` to stop it before restarting |
#### Understanding Test Failures
- **StorageUnknownError with "request failed"**: Infrastructure not running
- **Snapshot failures**: Expected test data has changed — review and update snapshots if needed

## Usage
First of all, you need to install the library:
```sh
npm install @supabase/supabase-js
```
Then you're able to import the library and establish the connection with the database:
```js
import { createClient } from '@supabase/supabase-js'
// Create a single supabase client for interacting with your database
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')
```
### UMD
You can use plain `<script>`s to import supabase-js from CDNs, like:
```html
<script src="https://cdn.jsdelivr.net/npm/@supabase/supabase-js@2"></script>
```
or even:
```html
<script src="https://unpkg.com/@supabase/supabase-js@2"></script>
```
Then you can use it from a global `supabase` variable:
```html
<script>
const { createClient } = supabase
const _supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')
console.log('Supabase Instance: ', _supabase)
// ...
</script>
```
### ESM
You can use `<script type="module">` to import supabase-js from CDNs, like:
```html
<script type="module">
import { createClient } from 'https://cdn.jsdelivr.net/npm/@supabase/supabase-js/+esm'
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key')
console.log('Supabase Instance: ', supabase)
// ...
</script>
```
### Deno
You can use supabase-js in the Deno runtime via [JSR](https://jsr.io/@supabase/supabase-js):
```js
import { createClient } from 'jsr:@supabase/supabase-js@2'
```
### Custom `fetch` implementation
`supabase-js` uses the [`cross-fetch`](https://www.npmjs.com/package/cross-fetch) library to make HTTP requests, but an alternative `fetch` implementation can be provided as an option. This is most useful in environments where `cross-fetch` is not compatible, for instance Cloudflare Workers:
```js
import { createClient } from '@supabase/supabase-js'
// Provide a custom `fetch` implementation as an option
const supabase = createClient('https://xyzcompany.supabase.co', 'public-anon-key', {
global: {
fetch: (...args) => fetch(...args),
},
})
```
## Support Policy
This section outlines the scope of support for various runtime environments in Supabase JavaScript client.
### Node.js
We only support Node.js versions that are in **Active LTS** or **Maintenance** status as defined by the [official Node.js release schedule](https://nodejs.org/en/about/previous-releases#release-schedule). This means we support versions that are currently receiving long-term support and critical bug fixes.
When a Node.js version reaches end-of-life and is no longer in Active LTS or Maintenance status, Supabase will drop it in a **minor release**, and **this won't be considered a breaking change**.
> ⚠️ **Node.js 18 Deprecation Notice**
>
> Node.js 18 reached end-of-life on April 30, 2025. As announced in [our deprecation notice](https://github.com/orgs/supabase/discussions/37217), support for Node.js 18 was dropped in version `2.79.0`.
>
> If you must use Node.js 18, please use version `2.78.0`, which is the last version that supported Node.js 18.
### Deno
We support Deno versions that are currently receiving active development and security updates. We follow the [official Deno release schedule](https://docs.deno.com/runtime/fundamentals/stability_and_releases/) and only support versions from the `stable` and `lts` release channels.
When a Deno version reaches end-of-life and is no longer receiving security updates, Supabase will drop it in a **minor release**, and **this won't be considered a breaking change**.
### Browsers
All modern browsers are supported. We support browsers that provide native `fetch` API. For Realtime features, browsers must also support native `WebSocket` API.
### Bun
We support Bun runtime environments. Bun provides native fetch support and is compatible with Node.js APIs. Since Bun does not follow a structured release schedule like Node.js or Deno, we support current stable versions of Bun and may drop support for older versions in minor releases without considering it a breaking change.
### React Native
We support React Native environments with fetch polyfills provided by the framework. Since React Native does not follow a structured release schedule, we support current stable versions and may drop support for older versions in minor releases without considering it a breaking change.
### Cloudflare Workers
We support Cloudflare Workers runtime environments. Cloudflare Workers provides native fetch support. Since Cloudflare Workers does not follow a structured release schedule, we support current stable versions and may drop support for older versions in minor releases without considering it a breaking change.
### Important Notes
- **Experimental features**: Features marked as experimental may be removed or changed without notice
## Known Build Warnings
### `UNUSED_EXTERNAL_IMPORT` in Vite / Rollup / Nuxt
When bundling your app, you may see warnings like:
```
"PostgrestError" is imported from external module "@supabase/postgrest-js" but never used in "...supabase-js/dist/index.mjs".
"FunctionRegion", "FunctionsError", "FunctionsFetchError", "FunctionsHttpError" and "FunctionsRelayError" are imported from external module "@supabase/functions-js" but never used in "...".
```
**This is a false positive — your bundle is fine.** Here is why it happens:
`@supabase/supabase-js` re-exports `PostgrestError`, `FunctionsError`, and related symbols so you can import them directly from `@supabase/supabase-js`. However, our build tool merges all imports from the same package into a single import statement in the built output:
```js
// dist/index.mjs (simplified)
import { PostgrestClient, PostgrestError } from '@supabase/postgrest-js'
// ^ used internally ^ re-exported for you
```
Your bundler checks which names from that import are used _in the code body_, and flags `PostgrestError` as unused because it only appears in an `export` statement — not called or assigned. The export itself is the usage, but downstream bundlers don't track this correctly. This is a known Rollup/Vite limitation with re-exported external imports.
**Nothing is broken.** Tree-shaking and bundle size are unaffected.
To suppress the warning:
**Vite / Rollup (`vite.config.js` or `rollup.config.js`):**
```js
export default {
build: {
rollupOptions: {
onwarn(warning, warn) {
if (warning.code === 'UNUSED_EXTERNAL_IMPORT' && warning.exporter?.includes('@supabase/'))
return
warn(warning)
},
},
},
}
```
**Nuxt (`nuxt.config.ts`):**
```ts
export default defineNuxtConfig({
vite: {
build: {
rollupOptions: {
onwarn(warning, warn) {
if (warning.code === 'UNUSED_EXTERNAL_IMPORT' && warning.exporter?.includes('@supabase/'))
return
warn(warning)
},
},
},
},
})
```

the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions

copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

load-script@1.0.0 ・ MIT
# load-script
Dynamic script loading.
## Installation
via component
```
$ component install eldargab/load-script
```
via npm
```
$ npm install load-script
```
## API
`load-script` appends a `script` node to the `<head>` element in the dom.
`require('load-script')` returns a function of the following interface: `function(url[, opts][, cb]) {}`
### url
Any url that you would like to load. May be absolute or relative.
### [, opts]
A map of options. Here are the currently supported options:
* `async` - A boolean value used for `script.async`. By default this is `true`.
* `attrs` - A map of attributes to set on the `script` node before appending it to the DOM. By default this is empty.
* `charset` - A string value used for `script.charset`. By default this is `utf8`.
* `text` - A string of text to append to the `script` node before it is appended to the DOM. By default this is empty.
* `type` - A string used for `script.type`. By default this is `text/javascript`.
### [, cb]
A callback function of the following interface: `function(err, script) {}` where `err` is an error if any occurred and `script` is the `script` node that was appended to the DOM.
## Example Usage
```javascript
var load = require('load-script')
load('foo.js', function (err, script) {
if (err) {
// print useful message
}
else {
console.log(script.src);// Prints 'foo'.js'
// use script
// note that in IE8 and below loading error wouldn't be reported
}
})
```

notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

react-youtube@10.1.0 ・ MIT
作者：Tjalling Tolle
  
# react-youtube
Simple [React](http://facebook.github.io/react/) component acting as a thin layer over the [YouTube IFrame Player API](https://developers.google.com/youtube/iframe_api_reference)
## Features
- url playback
- [playback event bindings](https://developers.google.com/youtube/iframe_api_reference#Events)
- [customizable player options](https://developers.google.com/youtube/player_parameters)
## Installation
### NPM
```bash
npm install react-youtube
```
### Yarn
```bash
yarn add react-youtube
```
### PNPM
```bash
pnpm add react-youtube
```
## Usage
```js
<YouTube
videoId={string} // defaults -> ''
id={string} // defaults -> ''
className={string} // defaults -> ''
iframeClassName={string} // defaults -> ''
style={object} // defaults -> {}
title={string} // defaults -> ''
loading={string} // defaults -> undefined
opts={obj} // defaults -> {}
onReady={func} // defaults -> noop
onPlay={func} // defaults -> noop
onPause={func} // defaults -> noop
onEnd={func} // defaults -> noop
onError={func} // defaults -> noop
onStateChange={func} // defaults -> noop
onPlaybackRateChange={func} // defaults -> noop
onPlaybackQualityChange={func} // defaults -> noop
/>
```
For convenience it is also possible to access the PlayerState constants through react-youtube:
`YouTube.PlayerState` contains the values that are used by the [YouTube IFrame Player API](https://developers.google.com/youtube/iframe_api_reference#onStateChange).
## Example
```jsx
// js
import React from 'react';
import YouTube from 'react-youtube';
class Example extends React.Component {
render() {
const opts = {
height: '390',
width: '640',
playerVars: {
// https://developers.google.com/youtube/player_parameters
autoplay: 1,
},
};
return <YouTube videoId="2g811Eo7K8U" opts={opts} onReady={this._onReady} />;
}
_onReady(event) {
// access to player in all event handlers via event.target
event.target.pauseVideo();
}
}
```
```tsx
// ts
import React from 'react';
import YouTube, { YouTubeProps } from 'react-youtube';
function Example() {
const onPlayerReady: YouTubeProps['onReady'] = (event) => {
// access to player in all event handlers via event.target
event.target.pauseVideo();
}
const opts: YouTubeProps['opts'] = {
height: '390',
width: '640',
playerVars: {
// https://developers.google.com/youtube/player_parameters
autoplay: 1,
},
};
return <YouTube videoId="2g811Eo7K8U" opts={opts} onReady={onPlayerReady} />;
}
```
## Controlling the player
You can access & control the player in a way similar to the [official api](https://developers.google.com/youtube/iframe_api_reference#Events):
> The ~~API~~ _component_ will pass an event object as the sole argument to each of ~~those functions~~ _the event handler props_. The event object has the following properties:
>
> - The event's `target` identifies the video player that corresponds to the event.
> - The event's `data` specifies a value relevant to the event. Note that the `onReady` event does not specify a `data` property.

for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
