| # p-defer [](https://travis-ci.org/sindresorhus/p-defer) |
| |
| > Create a deferred promise |
| |
| [**Don't use this unless you know what you're doing!**](https://github.com/petkaantonov/bluebird/wiki/Promise-anti-patterns#the-deferred-anti-pattern) Prefer the `Promise` constructor. |
| |
| |
| ## Install |
| |
| ``` |
| $ npm install --save p-defer |
| ``` |
| |
| |
| ## Usage |
| |
| ```js |
| const pDefer = require('p-defer'); |
| |
| function delay(ms) { |
| const deferred = pDefer(); |
| setTimeout(deferred.resolve, ms, '🦄'); |
| return deferred.promise; |
| } |
| |
| delay(100).then(console.log); |
| //=> '🦄' |
| ``` |
| |
| *The above is just an example. Use [`delay`](https://github.com/sindresorhus/delay) if you need to delay a promise.* |
| |
| |
| ## API |
| |
| ### pDefer() |
| |
| Returns an `Object` with a `promise` property and functions to `resolve()` and `reject()`. |
