@computesdk/daytona

@computesdk/daytona

Daytona provider for ComputeSDK - Execute code in Daytona development workspaces.

Installation

npm install @computesdk/daytona

Quick Start

Gateway Mode (Recommended)

Use the gateway for zero-config auto-detection:

import { compute } from 'computesdk';

// Auto-detects Daytona from DAYTONA_API_KEY environment variable
const sandbox = await compute.sandbox.create();

// Execute code
const result = await sandbox.runCommand('python -c "print(\"Hello from Daytona!\")"');
console.log(result.stdout); // "Hello from Daytona!"

await sandbox.destroy();

Direct Mode

For direct SDK usage without the gateway:

import { daytona } from '@computesdk/daytona';

const compute = daytona({ 
  apiKey: process.env.DAYTONA_API_KEY
});

const sandbox = await compute.sandbox.create();

const result = await sandbox.runCommand('python -c "print(\"Hello from Daytona!\")"');
console.log(result.stdout);

await sandbox.destroy();

Configuration

Environment Variables

export DAYTONA_API_KEY=your_api_key_here

Configuration Options

interface DaytonaConfig {
  /** Daytona API key - if not provided, will use DAYTONA_API_KEY env var */
  apiKey?: string;
  /** Default runtime environment */
  runtime?: 'python' | 'node';
  /** Execution timeout in milliseconds */
  timeout?: number;
}

Features

• ✅ Code Execution - Python and Node.js runtime support
• ✅ Command Execution - Run shell commands in workspace
• ✅ Filesystem Operations - Full file system access
• ✅ Auto Runtime Detection - Automatically detects Python vs Node.js
• ❌ Interactive Terminals - Not supported by Daytona SDK

API Reference

Code Execution

// Execute Python code
const result = await sandbox.runCommand(`python - <<'PY'
import json
data = {"message": "Hello from Python"}
print(json.dumps(data))
PY`);

// Execute Node.js code  
const result = await sandbox.runCommand(`node - <<'JS'
const data = { message: "Hello from Node.js" };
console.log(JSON.stringify(data));
JS`);

// Auto-detection (based on code patterns)
const result = await sandbox.runCommand('python -c "print(\"Auto-detected as Python\")"');

Command Execution

// List files
const result = await sandbox.runCommand('ls', ['-la']);

// Install packages
const result = await sandbox.runCommand('pip', ['install', 'requests']);

// Run scripts
const result = await sandbox.runCommand('python', ['script.py']);

Filesystem Operations

// Write file
await sandbox.filesystem.writeFile('/workspace/hello.py', 'print("Hello World")');

// Read file
const content = await sandbox.filesystem.readFile('/workspace/hello.py');

// Create directory
await sandbox.filesystem.mkdir('/workspace/data');

// List directory contents
const files = await sandbox.filesystem.readdir('/workspace');

// Check if file exists
const exists = await sandbox.filesystem.exists('/workspace/hello.py');

// Remove file or directory
await sandbox.filesystem.remove('/workspace/hello.py');

Sandbox Management

// Get sandbox info
const info = await sandbox.getInfo();
console.log(info.id, info.provider, info.status);

// List all sandboxes
const sandboxes = await compute.sandbox.list(provider);

// Get existing sandbox
const existing = await compute.sandbox.getById(provider, 'sandbox-id');

// Destroy sandbox
await compute.sandbox.destroy(provider, 'sandbox-id');

Runtime Detection

The provider automatically detects the runtime based on code patterns:

Python indicators:

• print( statements
• import statements
• def function definitions
• Python-specific syntax (f", __, etc.)

Default: Node.js for all other cases

Error Handling

import { daytona } from '@computesdk/daytona';

try {
  const compute = daytona({ apiKey: process.env.DAYTONA_API_KEY });
  const sandbox = await compute.sandbox.create();
  
  const result = await sandbox.runCommand('invalid code');
} catch (error) {
  if (error.message.includes('Syntax error')) {
    console.error('Code has syntax errors');
  } else if (error.message.includes('authentication failed')) {
    console.error('Check your DAYTONA_API_KEY');
  } else if (error.message.includes('quota exceeded')) {
    console.error('Daytona usage limits reached');
  }
}

Examples

Data Processing

import { daytona } from '@computesdk/daytona';

const compute = daytona({ apiKey: process.env.DAYTONA_API_KEY });
const sandbox = await compute.sandbox.create();

const result = await sandbox.runCommand(`python - <<'PY'
import json

# Process data
data = [1, 2, 3, 4, 5]
result = {
    "sum": sum(data),
    "average": sum(data) / len(data),
    "max": max(data)
}

print(json.dumps(result))
PY`);

const output = JSON.parse(result.stdout);
console.log(output); // { sum: 15, average: 3, max: 5 }

await sandbox.destroy();

File Processing

import { daytona } from '@computesdk/daytona';

const compute = daytona({ apiKey: process.env.DAYTONA_API_KEY });
const sandbox = await compute.sandbox.create();

// Create data file
await sandbox.filesystem.writeFile('/workspace/data.json', 
  JSON.stringify({ users: ['Alice', 'Bob', 'Charlie'] })
);

// Process file
const result = await sandbox.runCommand(`python - <<'PY'
import json

with open('/workspace/data.json', 'r') as f:
    data = json.load(f)

# Process users
user_count = len(data['users'])
print(f"Found {user_count} users")

# Save result
result = {"user_count": user_count, "processed": True}
with open('/workspace/result.json', 'w') as f:
    json.dump(result, f)
PY`);

// Read result
const resultData = await sandbox.filesystem.readFile('/workspace/result.json');
console.log(JSON.parse(resultData));

await sandbox.destroy();
