I recently saw Youtube's and Medium's new loading bars (and Medium don't get it) and was interested in implementing it on my own. In comes NProgress, a jQuery dependent plugin that creates this effect.
I didn't think the plugin needed a jQuery dependency, so I created my own AngularJS Provider that I can use for my heavy-applications. Try it out, fork it and submit a pull request if you want!
Right now, the plugin weighs 8kb, contains 12 different methods and has a dependency on Angular (duh).
Reach out to me on Twitter ( @VictorBjelkholm ) if you have feedback, criticisms or just want someone to blame for your problems. Or, visit the Github repository
Manual: Download ngProgress.js or ngProgress.min.js
Automatic: Install using bower:
bower install ngprogress
Include ngProgress.js ( or ngProgress.min.js) and ngProgress.css in your website.
<script src="app/components/ngProgress/ngProgress.js"></script> <link rel="stylesheet" href="ngProgress.css">
Set ngProgress as a dependency in your module
var app = angular.module('progressApp', ['ngProgress']);
Inject ngProgressFactory in the controller where you plan to use it
var MainCtrl = function($scope, ngProgressFactory) {
}
Create a new instance of ngProgress and start showing the progress of things!
$scope.progressbar = ngProgressFactory.createInstance();
$scope.progressbar.start();
Use this command to start the progress bar. The ngProgress API will show you how to manipulate ngProgress.
ngProgress.start();
ngProgressFactory.createInstance()
REQUIRED TO USE! Creates a new instance of ngProgress that you can use the methods below with.
ngProgress.start();
Starts the animation and adds between 0 - 5 percent to the loading percentage every 400 milliseconds. Should always be finished with progressbar.complete() to hide it.
ngProgress.height();
Sets the height of the progressbar. Use any valid CSS value Eg '10px', '1em' or '1%'.
ngProgress.color();
Sets the color of the progressbar and it's shadow. Use any valid HTML color
ngProgress.status();
Returns the current percent value the progressbar is at. Should'nt be needed.
ngProgress.stop();
Stops the progressbar at its current location.
ngProgress.set();
Sets the progressbar percentage value. Use a number between 0 - 100. If 100 is provided, complete will be called.
ngProgress.reset();
Resets the progressbar to percentage 0 and will be hiden after it's rolled back.
ngProgress.complete();
Jumps to 100% progress and fades away progressbar.
