Matt Brockman f7a97e698e enable http2 for js sdk envd rpc/api traffic (#1311)
Enables HTTP/2 for JS SDK sandbox envd traffic in Node by routing envd
RPC/API requests through undici with an HTTP/2-enabled dispatcher.

Non-Node runtimes continue to use global fetch. Management API and
volume clients are unchanged.

Requires bumping node from >=20 to >= 20.18.1 for undici

What is E2B?

E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.

Run your first Sandbox

1. Install SDK

npm i e2b

2. Get your E2B API key

  1. Sign up to E2B here.
  2. Get your API key here.
  3. Set environment variable with your API key
E2B_API_KEY=e2b_***

3. Start a sandbox and run commands

import Sandbox from 'e2b'

const sandbox = await Sandbox.create()
const result = await sandbox.commands.run('echo "Hello from E2B!"')
console.log(result.stdout) // Hello from E2B!

4. Code execution with Code Interpreter

If you need runCode(), install the Code Interpreter SDK:

npm i @e2b/code-interpreter
import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
const execution = await sandbox.runCode('x = 1; x += 1; x')
console.log(execution.text)  // outputs 2

5. Check docs
