What is teen_process?

The teen_process npm package provides utilities for executing system commands and managing child processes in Node.js. It simplifies the process of running shell commands, handling their output, and managing subprocesses.

What are teen_process's main functionalities?

exec

The `exec` function allows you to run shell commands and capture their output. In this example, the `ls -la` command is executed, and its output is logged to the console.

const { exec } = require('teen_process');

async function runCommand() {
  try {
    const { stdout, stderr } = await exec('ls', ['-la']);
    console.log('Output:', stdout);
    console.error('Error:', stderr);
  } catch (err) {
    console.error('Command failed:', err);
  }
}

runCommand();

spawn

The `spawn` function is used to launch a new process with a given command. This example demonstrates how to spawn the `ls -la` command and handle its stdout, stderr, and exit events.

const { spawn } = require('teen_process');

function runSpawn() {
  const child = spawn('ls', ['-la']);

  child.stdout.on('data', (data) => {
    console.log(`stdout: ${data}`);
  });

  child.stderr.on('data', (data) => {
    console.error(`stderr: ${data}`);
  });

  child.on('close', (code) => {
    console.log(`child process exited with code ${code}`);
  });
}

runSpawn();

execFile

The `execFile` function is similar to `exec`, but it is specifically designed for executing files. In this example, the `node -v` command is executed to get the Node.js version.

const { execFile } = require('teen_process');

async function runExecFile() {
  try {
    const { stdout, stderr } = await execFile('node', ['-v']);
    console.log('Node version:', stdout);
    console.error('Error:', stderr);
  } catch (err) {
    console.error('Command failed:', err);
  }
}

runExecFile();
