# Cloudflare Browser Run plugin

> Render and inspect pages, capture screenshots and PDFs, crawl sites, and manage Browser Rendering sessions and targets through REST.

Use **Cloudflare Browser Run** through Corsair: one client, typed API calls.

This plugin exposes 24 REST operations: `content.fetch`, `markdown.convert`, `snapshot.capture`, `accessibilityTree.capture`, `scrape.extract`, `json.extract`, `links.list`, `screenshot.capture`, `pdf.render`, `crawl.start`, `crawl.get`, `crawl.cancel`, `sessions.list`, `sessions.get`, `browser.create`, `browser.close`, `browser.version`, `browser.protocol`, `browser.liveView.create`, `targets.create`, `targets.list`, `targets.get`, `targets.activate`, and `targets.close`.

Quick Actions use the current `/browser-run` paths; DevTools use the generated API reference's `/browser-rendering/devtools` paths. Screenshot/PDF bytes are returned as base64 JSON. Browser DevTools WebSocket/CDP transport, Workers Bindings, and inbound webhooks are not implemented.

**What you get:**

* 24 typed API operations

## Setup

**1. Install**

```bash npm theme={null}
npm install corsair @corsair-dev/cloudflarebrowserrendering better-sqlite3
npm install --save-dev @types/better-sqlite3
```

```bash yarn theme={null}
yarn add corsair @corsair-dev/cloudflarebrowserrendering better-sqlite3
yarn add --dev @types/better-sqlite3
```

```bash pnpm theme={null}
pnpm install corsair @corsair-dev/cloudflarebrowserrendering better-sqlite3
pnpm install --save-dev @types/better-sqlite3
```

```bash bun theme={null}
bun add corsair @corsair-dev/cloudflarebrowserrendering better-sqlite3
bun add --dev @types/better-sqlite3
```

**2. Add the plugin**

```ts corsair.ts theme={null}
import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { cloudflarebrowserrendering } from '@corsair-dev/cloudflarebrowserrendering';

export const corsair = createCorsair({
	plugins: [
		cloudflarebrowserrendering({
			authType: 'api_key',
		}),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});
```

With `multiTenancy: true`, scope calls with `corsair.withTenant(id)`. See [Quick start](https://docs.corsair.dev/quick-start.md) for KEK + Hub keys, and [Multi-tenancy](https://docs.corsair.dev/concepts/multi-tenancy.md) for account isolation.

**3. Choose authentication**

> [tab] API Key (Recommended)
>
> Store the Cloudflare Browser Run API key before the first call: `pnpm corsair setup --plugin=cloudflarebrowserrendering --tenant=acme api_key=<your-key>` (leave out `--tenant` without `multiTenancy`), or pass it as `key` in the plugin options. With Hub, each tenant enters their own key on the connect page. See [API key auth](https://docs.corsair.dev/concepts/api-key).

> ```ts theme={null}
> cloudflarebrowserrendering({
> 	authType: 'api_key',
> })

**4. Connect a tenant**

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see [Connect / OAuth](https://docs.corsair.dev/management/connect).

```ts theme={null}
const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'cloudflarebrowserrendering',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl
```

## Example API calls

**Fetch rendered HTML**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.cloudflarebrowserrendering.api.content.fetch({
	accountId: 'acct-123',
	body: { url: 'https://example.com' },
});
```

**Create a browser session**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.cloudflarebrowserrendering.api.browser.create({
	accountId: 'acct-123',
	keepAlive: 60000,
	guardrails: {
		allowedDomains: ['example.com'],
	},
});
```
