Atocha

Run a command in your terminal. Tiny exec() with promises and trim() for Node.js:

import cmd from 'atocha';

(async () => {
  // Any basic command will work
  console.log(await cmd('ls'));

  // Using a better Promise interface, see the lib `swear`
  console.log(await cmd('ls').split('\n'));

  // Can pipe commands as normal
  console.log(await cmd('sort record.txt | uniq'));
})();

Terminal Atocha; Madrid's train station.

Better exec()

• Automatic .trim() so you don't have to do it manually.
• Higher max buffer. 10 MB instead of 200 KB.
• Await/Async Promise interface works as you know and love.
• Better error handling. stderr will reject the promise with an error instance. Can be caught as normal with .catch() or try {} catch (error) {}.
• Advanced Promise interface so you can concatenate operations easily.
• Full commands, commands with piping, etc. Note: Do not pass unsanitized input since there's no filtering going on. See execa for that.

Getting started

Install it in your project:

npm install atocha

Import it to be able to use it in your code:

const cmd = require('atocha');  // Old school
import cmd from 'atocha';       // New wave
