What is @actions/exec?

@actions/exec is an npm package designed to facilitate the execution of shell commands within GitHub Actions workflows. It provides a simple and flexible API to run commands, capture their output, and handle errors.

What are @actions/exec's main functionalities?

Basic Command Execution

This feature allows you to execute basic shell commands. In this example, the 'echo' command is used to print 'Hello, world!' to the console.

const exec = require('@actions/exec');

async function run() {
  await exec.exec('echo', ['Hello, world!']);
}

run();

Capture Output

This feature allows you to capture the output and error streams of the executed command. In this example, the 'node -v' command is executed, and its output and error streams are captured and printed to the console.

const exec = require('@actions/exec');

async function run() {
  let myOutput = '';
  let myError = '';

  const options = {};
  options.listeners = {
    stdout: (data) => {
      myOutput += data.toString();
    },
    stderr: (data) => {
      myError += data.toString();
    }
  };

  await exec.exec('node', ['-v'], options);
  console.log('Output:', myOutput);
  console.log('Error:', myError);
}

run();

Command with Options

This feature allows you to execute commands with additional options such as the working directory and environment variables. In this example, the 'ls -la' command is executed in a specified working directory with a custom environment variable.

const exec = require('@actions/exec');

async function run() {
  const options = {
    cwd: '/path/to/working/directory',
    env: { MY_VAR: 'value' }
  };

  await exec.exec('ls', ['-la'], options);
}

run();
