## Requirements
- **Node.js 22 or later** (Node.js 20 support dropped in v2.110.0)
- 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.
> ⚠️ **Node.js 20 Deprecation Notice**
>
> Node.js 20 reached end-of-life on April 30, 2026. As announced in [our deprecation notice](https://github.com/orgs/supabase/discussions/45715), support for Node.js 20 was dropped in v2.110.0.
## 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 publishableKey = '<publishable_key>'
const functions = new FunctionsClient(functionsUrl, {
headers: {
Authorization: `Bearer ${publishableKey}`,
},
})
// 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)
pnpm nx build functions-js
# Build with watch mode for development
pnpm nx build functions-js --watch
# Individual build targets
pnpm nx build:main functions-js # CommonJS build (dist/main/)
pnpm nx build:module functions-js # ES Modules build (dist/module/)
# Other useful commands
pnpm nx clean functions-js # Clean build artifacts
pnpm nx typecheck functions-js # TypeScript type checking
pnpm 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)
pnpm nx test functions-js
# Run tests with coverage report
pnpm nx test functions-js --coverage
# Run tests in watch mode during development
pnpm nx test functions-js --watch
# CI test command (runs with coverage)
pnpm nx test:ci functions-js
```
#### Test Requirements
- **Node.js 22+** - 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
