# request-progress [](http://travis-ci.org/IndigoUnited/node-request-progress.png) Tracks the download progress of a request made with [request](https://github.com/mikeal/request). ## Installation `$ npm install request-progress` ## Usage ```js var fs = require('fs'); var request = require('request'); var progress = require('request-progress'); // Note that the options argument is optional progress(request('http://google.com/doodle.png'), { throttle: 2000, // Throttle the progress event to 2000ms, defaults to 1000ms delay: 1000 // Only start to emit after 1000ms delay, defaults to 0ms }) .on('progress', function (state) { console.log('received size in bytes', state.received); // The properties bellow can be null if response does not contain // the content-length header console.log('total size in bytes', state.total); console.log('percent', state.percent); }) .on('error', function (err) { // Do something with err }) .pipe(fs.createWriteStream('doodle.png')) .on('error', function (err) { // Do something with err }) .on('close', function (err) { // Saved to doogle.png! }) ``` Note that the `state` object emitted in the `progress` event is reused to avoid creating a new object for each event. ## License Released under the [MIT License](http://www.opensource.org/licenses/mit-license.php).
