# native-or-bluebird [![NPM version][npm-image]][npm-url] [![Build status][travis-image]][travis-url] [![Test coverage][coveralls-image]][coveralls-url] [![Dependency Status][david-image]][david-url] [![License][license-image]][license-url] [![Downloads][downloads-image]][downloads-url] [![Gittip][gittip-image]][gittip-url] 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 ``` [npm-image]: https://img.shields.io/npm/v/native-or-bluebird.svg?style=flat-square [npm-url]: https://npmjs.org/package/native-or-bluebird [github-tag]: http://img.shields.io/github/tag/normalize/native-or-bluebird.svg?style=flat-square [github-url]: https://github.com/normalize/native-or-bluebird/tags [travis-image]: https://img.shields.io/travis/normalize/native-or-bluebird.svg?style=flat-square [travis-url]: https://travis-ci.org/normalize/native-or-bluebird [coveralls-image]: https://img.shields.io/coveralls/normalize/native-or-bluebird.svg?style=flat-square [coveralls-url]: https://coveralls.io/r/normalize/native-or-bluebird?branch=master [david-image]: http://img.shields.io/david/normalize/native-or-bluebird.svg?style=flat-square [david-url]: https://david-dm.org/normalize/native-or-bluebird [license-image]: http://img.shields.io/npm/l/native-or-bluebird.svg?style=flat-square [license-url]: LICENSE [downloads-image]: http://img.shields.io/npm/dm/native-or-bluebird.svg?style=flat-square [downloads-url]: https://npmjs.org/package/native-or-bluebird [gittip-image]: https://img.shields.io/gittip/jonathanong.svg?style=flat-square [gittip-url]: https://www.gittip.com/jonathanong/
