About this version
Useful additions to inbuilt child_process module.
📦 Node.js,
📜 Files,
📰 Docs.
This package provides async versions of functions (in additon to the
existing sync and callback-based functions), which are not included with the
inbuilt child_process module. They are named as *Async can be used with
Promise-based asynchronous programming using the await keyword.
spawnAsync is a special case here, which returns a PromiseWithChild which is
essentially a Promise with a .child property to allow ChildProcess to be
directly accessed similar to spawn. In addition, functions for
locating path of executables such as which and whichAll are included.
Design was based on personal ideas and literature survey.
Stability: Experimental.
const cp = require('extra-child-process');
// cp.exec(command, options)
// cp.execFile(file, args, options)
async function main() {
// With Promise:
var {stdout, stderr} = await cp.exec('ls -a', {cwd: '/home'});
var {stdout, stderr} = await cp.execFile('ls', ['-a'], {cwd: '/home'});
// Without Promise:
cp.exec('ls -a', {cwd: '/home'}, (err, stdout, stderr) => 0);
cp.execFile('ls', ['-a'], {cwd: '/home'}, (err, stdout, stderr) => 0);
}
