Сразу расскажу про несколько особенностей яваскрипта, о которых может быть не написано (или мало написано) в учебниках, но которые стоит понимать:

#Error management in gulp

Sucking at something is the first step to becoming sorta good at something

No one can assure you, that plugins will run smooth in any circumstances (except for tests - they could), so neither should you convince anyone, that your plugin will never break. Only thing, that you could possibly do (if something gone wrong) - is gracefully inform your plugin user, that something went wrong and die.

We are will use this plugin from beginning to demonstrate error management. Suppose you have a task in gulpfile.js that contains this code (we modified it a little bit to be closer to real-usage):

var coffee = require('gulp-coffee');

	function PrivateRoute ({component: Component, authenticated, ...rest}) {
	return (
	<Route
	{...rest}
	render={(props) => authenticated === true
	? <Component {...props} />
	: <Redirect to={{pathname: '/login', state: {from: props.location}}} />}
	/>
	)
	}

	const obj1 = {name:"xiaoming", age: 23}
	const obj2 = {age: 33}
	const obj3 = {...obj1, ...obj2}
	//obj3 ==> {"name":"xiaoming","age":33}

	git branch -m old_branch new_branch # Rename branch locally
	git push origin :old_branch # Delete the old branch
	git push --set-upstream origin new_branch # Push the new branch, set local branch to track the new remote

	ps aux \| grep node
	kill -9 PID

	(Replace PID with the process Id of the Node)
