E2B

E2B provider for ComputeSDK - Execute code in full development environments with terminal support.

Installation

npm install @computesdk/e2b

Usage

With ComputeSDK

import { createCompute } from 'computesdk';
import { e2b } from '@computesdk/e2b';

// Set as default provider
const compute = createCompute({ 
  provider: e2b({ apiKey: process.env.E2B_API_KEY }),
  apiKey: process.env.COMPUTESDK_API_KEY 
});

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

// Get instance
const instance = sandbox.getInstance();

// Execute code
const result = await sandbox.runCode('print("Hello from E2B!")');
console.log(result.stdout); // "Hello from E2B!"

// Clean up
await compute.sandbox.destroy(sandbox.sandboxId);

Configuration

Environment Variables

export E2B_API_KEY=e2b_your_api_key_here

Configuration Options

interface E2BConfig {
  /** E2B API key - if not provided, will use E2B_API_KEY env var */
  apiKey?: string;
  /** Environment template to use */
  runtime?: 'node' | 'python';
  /** Execution timeout in milliseconds */
  timeout?: number;
}

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
