sandboxjs

A unified interface for Linux-based cloud sandbox providers. It can be used to create the building blocks of AI agents that run code or perform other potentially unsafe operations.

Usage

import Sandbox from "@gitwit/sandbox";

// Create a new sandbox
const sandbox = await Sandbox.create("daytona"); // or "codesandbox" or "e2b"

// Connect to an existing sandbox
// const sandbox = await Sandbox.connect("daytona", "sandbox_id");

// Run commands and interact with the sandbox
console.log(await sandbox.runCommand("echo 'hello world'"));
console.log(await sandbox.listFiles("/"));

// Suspend, resume and destroy the sandbox
await sandbox.suspend();
await sandbox.resume();
await sandbox.destroy();

Provider Support

Provider	File Persistence	Memory Persistence	Read/Write Files	Recursive Delete	Directory Watch	Preview URLs	Pseudo-terminals	Destroy Sandbox
E2B	✅	✅	✅	✅	✅	✅	✅	✅
Daytona	✅	❌	✅	❌	❌	✅	❌	✅
CodeSandbox	✅	✅	✅	✅	✅	✅	✅	❌

Getting Started

1. Set up environment variables

Create a .env file in the root directory of the project and add at least one of the following environment variables:

# Get an E2B API key here: https://e2b.dev/dashboard
E2B_API_KEY=
# Get a Daytona API key here: https://app.daytona.io/dashboard/keys
DAYTONA_API_KEY=
# Get a CodeSandbox API key here: https://codesandbox.io/t
CODESANDBOX_API_KEY=

2. Install dependencies

npm install

3. Build the project

Compiles the TypeScript source files to JavaScript in the dist/ directory.

npm run build

4. Run the example

After building, run the example script:

node dist/example.js

5. Run tests

To run the test suite:

npm test
