Documentation

To stream command output as it is being executed, pass the onStdout, onStderr callbacks to the commands.run() method in JavaScript or the on_stdout, on_stderr callbacks to the commands.run() method in Python.

import { Sandbox } from 'e2b'

const sandbox = await Sandbox.create()

const result = await sandbox.commands.run('echo hello; sleep 1; echo world', {
  onStdout: (data) => {
    console.log(data)
  },
  onStderr: (data) => {
    console.log(data)
  },
})
console.log(result)

from e2b import Sandbox

sandbox = Sandbox.create()

result = sandbox.commands.run('echo hello; sleep 1; echo world', on_stdout=lambda data: print(data), on_stderr=lambda data: print(data))
print(result)
