|

|
|
> 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()`.
