node-respond/main.js

node-respond is an auto-responding Async CLI/CMD wrapper for NodeJS with a syntax based on

module.exports = ((cmd, args, shell) => {
	const {spawn} = require('child_process');
	let t,
		spawnedCmd = spawn(cmd, args, {shell: shell === false || true}),
		stdout = spawnedCmd.stdout

	stdout
	.on('data', (d) => {
		let data = d.toString().trim();
