​
Overview

The Computer class is the core interface for interacting with virtual computers in cuse. It provides access to system-level controls for display, mouse, keyboard, bash commands, and file editing capabilities.

​
Configuration

When creating a new Computer instance, you can configure its properties:

const computer = new Computer({
  config: {
    baseUrl: 'http://localhost:4242/your-computer-name',
    display: {  // optional
      number: 1,
      width: 1024,
      height: 768
    }
  }
});

​
Configuration Options

PropertyTypeDefaultDescription
baseUrlstringrequiredThe base URL for the computer’s API endpoint
display.numbernumber1Display number to control
display.widthnumber1024Display width in pixels
display.heightnumber768Display height in pixels

​
System Interface

The Computer provides access to several system-level interfaces through computer.system:

​
Display Control

Control the computer’s display:

// Take a screenshot of the current display
const screenshot = await computer.system.display.getScreenshot();

​
Mouse Control

Control mouse movements and clicks:

// Move mouse cursor
await computer.system.mouse.move({ x: 100, y: 200 });

// Get cursor position
const { x, y } = await computer.system.mouse.getPosition();

// Mouse clicks
await computer.system.mouse.leftClick();
await computer.system.mouse.rightClick();
await computer.system.mouse.middleClick();
await computer.system.mouse.doubleClick();

​
Keyboard Control

Simulate keyboard input:

// Press a single key
await computer.system.keyboard.pressKey({ key: 'enter' });

// Type text
await computer.system.keyboard.type({ text: 'Hello, World!' });

​
Bash Commands

Execute shell commands:

// Execute a command
const output = await computer.system.bash.execute({ 
  command: 'ls -la' 
});

// Restart the system
await computer.system.bash.restart();

​
File Editor

Manipulate files on the computer:

// View file contents
const content = await computer.system.editor.viewFile({
  path: '/path/to/file',
  viewRange: [1, 10] // optional: view specific lines
});

// Create a new file
await computer.system.editor.createFile({
  path: '/path/to/new/file',
  content: 'Hello, World!' // optional
});

// Replace text in a file
await computer.system.editor.replaceString({
  path: '/path/to/file',
  oldStr: 'old',
  newStr: 'new'
});

// Insert text at a specific line
await computer.system.editor.insertText({
  path: '/path/to/file',
  line: 5,
  text: 'New line content'
});

// Undo last edit
await computer.system.editor.undoLastEdit();

​
Keychain

The Computer class includes a Keychain app that allows you to manage your passwords and credentials.

// Store credentials in keychain
await computer.keychain.setKey('my-service', {
  username: 'user123',
  password: 'securepass'
});

// Load credentials from keychain
const credentials = await computer.keychain.getKey('my-service');

​
Lifecycle Methods

The Computer class includes methods for managing the computer’s lifecycle:

// Shutdown the computer and all running apps
computer.shutdown();
