p-defer

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

import pDefer from 'p-defer';

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

console.log(await delay(100));
//=> '🦄'

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

API
