# promise-each [![NPM version][npm-image]][npm-url] [![build status][travis-image]][travis-url] [![Test coverage][coveralls-image]][coveralls-url] [![Downloads][downloads-image]][downloads-url] Call a function [for each][mdn] value in an array and return a [Promise][promise]. Should only be used for side effects. Waits for promises to resolve before proceeding to the next value. ## Installation ```bash $ npm install promise-each ``` ## Usage ```js const each = require('promise-each') Promise.resolve([1, 2, 3]) .then(each((val) => console.log(val))) // => 1 // => 2 // => 3 ``` ## Why? This module is basically equivalent to [`bluebird.each`][bluebird], but it's handy to have the one function you need instead of a kitchen sink. Modularity! Especially handy if you're serving to the browser and need to reduce your javascript bundle size. Works great in the browser with [browserify](http://github.com/substack/node-browserify)! ## See Also - [promise-every](https://github.com/yoshuawuyts/promise-every) - [promise-filter](https://github.com/yoshuawuyts/promise-filter) - [promise-map](https://github.com/yoshuawuyts/promise-map) - [promise-reduce](https://github.com/yoshuawuyts/promise-reduce) - [promise-some](https://github.com/yoshuawuyts/promise-some) ## License [MIT](https://tldrlegal.com/license/mit-license) [npm-image]: https://img.shields.io/npm/v/promise-each.svg?style=flat-square [npm-url]: https://npmjs.org/package/promise-each [travis-image]: https://img.shields.io/travis/yoshuawuyts/promise-each.svg?style=flat-square [travis-url]: https://travis-ci.org/yoshuawuyts/promise-each [coveralls-image]: https://img.shields.io/coveralls/yoshuawuyts/promise-each.svg?style=flat-square [coveralls-url]: https://coveralls.io/r/yoshuawuyts/promise-each?branch=master [downloads-image]: http://img.shields.io/npm/dm/promise-each.svg?style=flat-square [downloads-url]: https://npmjs.org/package/promise-each [mdn]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/each [promise]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise [bluebird]: https://github.com/petkaantonov/bluebird/blob/master/API.md#eachfunction-iterator---promise
