p-defer

Create a deferred promise

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

Install

$ npm install --save 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

Returns an Object with a promise property and functions to resolve() and reject().
