p-defer

Create a deferred promise

Don't use this unless you know what you're doing. Prefer the Promise constructor.

Install

$ npm install p-defer

Usage

const pDefer = require('p-defer');

function delay(ms) {
	const deferred = pDefer();
	setTimeout(deferred.resolve, ms, '????');
	return deferred.promise;
}

(async () => {
	console.log(await delay(100));
	//=> '????'
})();

The above is just an example. Use delay if you need to delay a promise.

API
