# Write text at the current cursor position with customizable typing speed
desktop.write("Hello, world!")  # Default: chunk_size=25, delay_in_ms=75
desktop.write("Fast typing!", chunk_size=50, delay_in_ms=25)  # Faster typing

# Press keys
desktop.press("enter")
desktop.press("space")

await desktop.press('enter')
await desktop.press('space')
await desktop.press('backspace')
await desktop.press('ctrl+c') // Copy

Screenshot

Python

from e2b_desktop import Sandbox
desktop = Sandbox()

# Take a screenshot and save it as "screenshot.png" locally
image = desktop.screenshot()
# Save the image to a file

    f.write(image)

fs.writeFileSync('screenshot.png', image)

Open file

Python

from e2b_desktop import Sandbox
desktop = Sandbox()

# Open file with default application
desktop.files.write("/home/user/index.js", "console.log('hello')") # First create the file
desktop.open("/home/user/index.js") # Then open it

JavaScript

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Open file with default application
await desktop.files.write('/home/user/index.js', "console.log('hello')") // First create the file
await desktop.open('/home/user/index.js') // Then open it

Run any bash commands

Python

from e2b_desktop import Sandbox

const desktop = await Sandbox.create()

// Run any bash command
const out = await desktop.commands.run('ls -la /home/user')
console.log(out)

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. Check out the sandbox template's code here.
