|
Use either `bluebird` or the native `Promise` implementation.
|
|
If no implementation is found, an error will be thrown:
|
|
|
|
```js
|
|
var Promise = require('native-or-bluebird');
|
|
```
|
|
|
|
The goal of this library is to be able to eventually remove this line
|
|
from your code and use native `Promise`s, allowing you to
|
|
to write future-compatible code with ease.
|
|
You should install `bluebird` in your libraries for maximum compatibility.
|
|
|
|
If you do not want an error to be thrown,
|
|
`require()` the `Promise` implementation directly.
|
|
If no implementation is found, `undefined` will be returned.
|
|
|
|
```js
|
|
var Promise = require('native-or-bluebird/promise');
|
|
if (Promise) // do stuff with promises
|
|
```
