🚀 Getting started

The E2B Desktop Sandbox is built on top of E2B Sandbox.

$3

Sign up at E2B and get your API key.
Set environment variable E2B_API_KEY with your API key.

$3

``bash
npm install @e2b/desktop
`

$3

`javascript
import { Sandbox } from '@e2b/desktop'

// Start a new desktop sandbox
const desktop = await Sandbox.create()

// Launch an application
await desktop.launch('google-chrome') // or vscode, firefox, etc.

// Wait 10s for the application to open
await desktop.wait(10000)

// Stream the application's window
// Note: there can be only one stream at a time
// You need to stop the current stream before streaming another application
await desktop.stream.start({
windowId: await desktop.getCurrentWindowId(), // if not provided the whole desktop will be streamed
requireAuth: true,
})

// Get the stream auth key
const authKey = desktop.stream.getAuthKey()

// Print the stream URL
console.log('Stream URL:', desktop.stream.getUrl({ authKey }))

// Kill the sandbox after the tasks are finished
// await desktop.kill()

`javascript
import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Start the stream
await desktop.stream.start()

// Get stream URL
const url = desktop.stream.getUrl()
console.log(url)

// Stop the stream
await desktop.stream.stop()
`

$3

`javascript
import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Start the stream
await desktop.stream.start({
requireAuth: true, // Enable authentication with an auto-generated key
})

// Retrieve the authentication key
const authKey = await desktop.stream.getAuthKey()

// Get stream URL
const url = desktop.stream.getUrl({ authKey })
console.log(url)

// Stop the stream
await desktop.stream.stop()
`

> [!WARNING]
>
> - Will throw an error if the desired application is not open yet
> - The stream will close once the application closes
> - Creating multiple streams at the same time is not supported, you may have to stop the current stream and start a new one for each application

`javascript
import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Get current (active) window ID
const windowId = await desktop.getCurrentWindowId()

// Get all windows of the application
const windowIds = await desktop.getApplicationWindows('Firefox')

// Start the stream
await desktop.stream.start({ windowId: windowIds[0] })

// Stop the stream
await desktop.stream.stop()

await desktop.rightClick(100, 200)
await desktop.middleClick()
await desktop.middleClick(100, 200)
await desktop.scroll(10) // Scroll by the amount. Positive for up, negative for down.
await desktop.moveMouse(100, 200) // Move to x, y coordinates
await desktop.drag([100, 100], [200, 200]) // Drag using the mouse

Under the hood

The desktop-like environment is based on Linux and Xfce at the moment. We chose Xfce because it's a fast and lightweight environment that's also popular and actively supported. However, this Sandbox template is fully customizable and you can create your own desktop environment.
