Deploy serverless browser automation as cloud functions using Browserbase. Use when the user wants to deploy browser automation to run on a schedule or cron, create a webhook endpoint for browser tasks, run automation in the cloud instead of locally, or asks about Browserbase Functions.

# Browserbase Functions
Deploy serverless browser automation using the official `browse` CLI.
## Prerequisites
Get an API key from: https://browserbase.com/settings
```bash
export BROWSERBASE_API_KEY="your_api_key"
```
## Creating a Function Project
### 1. Initialize
```bash
browse functions init my-function
cd my-function
```
This creates:
```
my-function/
├── package.json
├── index.ts # Your function code
└── .env # Add credentials here
```
### 2. Add Credentials to .env
```bash
echo "BROWSERBASE_API_KEY=$BROWSERBASE_API_KEY" >> .env
```
### 3. Install Dependencies
```bash
pnpm install
```
## Function Structure
```typescript
import { defineFn } from "@browserbasehq/sdk-functions";
import { chromium } from "playwright-core";
defineFn("my-function", async (context) => {
const { session, params } = context;
// Connect to browser
const browser = await chromium.connectOverCDP(session.connectUrl);
const page = browser.contexts()[0]!.pages()[0]!;
// Your automation
await page.goto(params.url || "https://example.com");
const title = await page.title();
// Return JSON-serializable result
return { success: true, title };
});
```
**Key objects:**
- `context.session.connectUrl` - CDP endpoint to connect Playwright
- `context.params` - Input parameters from invocation
## Development Workflow
### 1. Start Dev Server
```bash
browse functions dev index.ts
```
Server runs at `http://127.0.0.1:14113`
### 2. Test Locally
```bash
curl -X POST http://127.0.0.1:14113/v1/functions/my-function/invoke \
-H "Content-Type: application/json" \
-d '{"params": {"url": "https://news.ycombinator.com"}}'
```
### 3. Iterate
The dev server auto-reloads on file changes. Use `console.log()` for debugging - output appears in the terminal.
## Deploying
```bash
browse functions publish index.ts
```
Output:
```
Function published successfully
Build ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
Function ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
```
**Save the Function ID** - you need it to invoke.
