# Introduction An implementation of [Promises/A+](http://promisesaplus.com/) using ES6, and [Chinese specification](https://github.com/mingmingwon/a-promise-lib/blob/master/spec_cn.md) of Promises/A+. # Install [](https://nodei.co/npm/a-promise-lib/) ```node npm i a-promise-lib ``` # Usage ```js let Promise = require('a-promise-lib') let promise = new Promise((resolve, reject) => { setTimeout(resolve, 1000, 'Success') }).then(res => { console.log(res) return Promise.resolve('Yeah') }) ;(async () => { const ret = await promise console.log(ret) })() ``` # API This library has achieved all the APIs same as JavaScript Standard built-in [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise), including static methods: - `Promise.resolve` - `Promise.reject` - `Promise.all` - `Promise.race` and prototype methods: - `Promise.prototype.then` - `Promise.prototype.catch` - `Promise.prototype.finally` and others: - `Promise.deferred` - `Promise.prototype.done` # Compliances Test Refer to [Promises/A+ Compliance Test Suite](https://github.com/promises-aplus/promises-tests). ```node npm run test ``` will see the result like this: ```bash 872 passing (17s) ``` # License The MIT License (MIT)
