Programmatic video recordings for web apps. Define interactions in JSON, get polished screen recordings out.

*Demo video generated with testreel*

- **Let your LLM agent generate product videos** - Just point your agent at this repo and ask it to generate a demo video for your product. Testreel integrates with Playwright, which allows your agent to create recordings with mocks and demo data easily.
- **Repeatable editable video config** - Instead of having to manually re-record a video because of a typo or a missed click, just edit the config and rerun the recording. Programmatically generate videos with polished background, and cursor and zoom animations.

## Features

- **Animated cursor** — configurable style, size, and click ripple effects
- **Window chrome** — macOS-style title bar with traffic lights
- **Background styling** — padding, rounded corners, solid or gradient backgrounds
- **Multiple auth methods** — setup blocks, localStorage/cookies injection, storage state files, interactive login, Supabase provider
- **Playwright integration** — test fixture and `recordPage()` API for existing test suites
- **Output formats** — WebM (default), MP4, GIF

## Install

```bash
npm install testreel playwright
npx playwright install chromium
```

## Quick start

Create a recording definition (`recording.json`):

```json
{
  "url": "https://example.com",
  "viewport": { "width": 1280, "height": 720 },
  "steps": [
    { "action": "click", "selector": "button.sign-in" },
    { "action": "fill", "selector": "#email", "text": "user@example.com" },
    { "action": "screenshot", "name": "filled-form" },
    { "action": "click", "selector": "button[type=submit]" },
    { "action": "wait", "ms": 2000 }
  ]
}
```

Run it:

```bash
npx testreel recording.json
```

Output goes to `./testreel-output/` — a WebM video, PNG screenshots, and an `output.json` manifest.

### CLI

```bash
npx testreel recording.json                       # basic recording
npx testreel recording.json --headed              # visible browser
npx testreel recording.json --format gif          # GIF output
npx testreel recording.json --setup login.json    # separate setup file
npx testreel validate recording.json              # validate without recording
npx testreel login https://app.com --save-state state.json  # interactive login
npx testreel init                                 # create a definition interactively
```

### API

```js
import { record, loadDefinition } from 'testreel'

const def = loadDefinition('recording.json')
const result = await record(def, { outputDir: './output' })

console.log(result.video)       // path to .webm file
console.log(result.screenshots) // array of .png paths
```

### Playwright test fixture

Already have a Playwright test suite? Add recording to any test — just change `test` to `recorded`:

```js
import { test, expect } from '@playwright/test'
import { testreelFixtures, type TestreelFixtures } from 'testreel/playwright'

const recorded = test.extend<TestreelFixtures>({
  ...testreelFixtures,
})

// This test is unchanged — no recording
test('health check', async ({ page }) => {
  await page.goto('/health')
  await expect(page.locator('.status')).toHaveText('OK')
})

// Just swap test → recorded — video is attached to the test report automatically
recorded('product demo', async ({ page }) => {
  await page.goto('https://myapp.com')
  await page.click('.login-button')
  await page.fill('#email', 'user@example.com')
})
```

Recordings are captured regardless of test outcome — partial videos are attached to the report for debugging. See [Playwright Integration](docs/playwright.md) for composing with custom fixtures, the `PageRecorder` API, and configuration options.

### recordPage API

For manual control over recording within any Playwright script:

```js
import { recordPage } from 'testreel'

// page must belong to a context created with recordVideo
const recorder = await recordPage(page, { chrome: true })
await recorder.click('.button')
await recorder.type('#search', 'hello')
const result = await recorder.stop() // finalizes video + post-processing
console.log(result.video)
```
