NProgress

Slim progress bars for Ajax'y applications. Inspired by Google, YouTube, and Medium.

Installation

Add nprogress.js and nprogress.css to your project.

<script src='nprogress.js'></script>
<link rel='stylesheet' href='nprogress.css'/>

NProgress is available via bower and npm and spm.

$ bower install --save nprogress
$ npm install --save nprogress

Basic usage

Simply call start() and done() to control the progress bar.

NProgress.start();
NProgress.done();

Using Turbolinks or similar? Ensure you're using Turbolinks 1.3.0+, and use this: (explained

[here](https://github.com/rstacruz/nprogress/issues/8#issuecomment-23010560))

$(document).on('page:fetch',   function() { NProgress.start(); });
$(document).on('page:change',  function() { NProgress.done(); });
$(document).on('page:restore', function() { NProgress.remove(); });

Ideas

• Add progress to your Ajax calls! Bind it to the jQuery ajaxStart and ajaxStop events.

• Make a fancy loading bar even without Turbolinks/Pjax! Bind it to $(document).ready and $(window).load.

Advanced usage

Percentages: To set a progress percentage, call .set(n), where n is a number between 0..1.

NProgress.set(0.0);     // Sorta same as .start()
NProgress.set(0.4);
NProgress.set(1.0);     // Sorta same as .done()

Incrementing: To increment the progress bar, just use .inc(). This increments it with a random amount. This will never get to 100%: use it for every image load (or similar).

NProgress.inc();

If you want to increment by a specific value, you can pass that as a parameter:

NProgress.inc(0.2);    // This will get the current status value and adds 0.2 until status is 0.994

Force-done: By passing true to done(), it will show the progress bar even if it's not being shown. (The default behavior is that .done() will not

do anything if *.start()* isn't called)

NProgress.done(true);

Get the status value: To get the status value, use .status

Configuration

minimum

Changes the minimum percentage used upon starting. (default: 0.08)

NProgress.configure({ minimum: 0.1 });

template

You can change the markup using template. To keep the progress bar working, keep an element with role='bar' in there. See the default template for reference.

NProgress.configure({
  template: "<div class='....'>...</div>"
});

easing and speed

Adjust animation settings using easing (a CSS easing string) and speed (in ms). (default: ease and 200)

NProgress.configure({ easing: 'ease', speed: 500 });

trickle

Turn off the automatic incrementing behavior by setting this to false. (default: true)

NProgress.configure({ trickle: false });

trickleRate and trickleSpeed

You can adjust the trickleRate (how much to increase per trickle) and trickleSpeed (how often to trickle, in ms).

NProgress.configure({ trickleRate: 0.02, trickleSpeed: 800 });

showSpinner

Turn off loading spinner by setting it to false. (default: true)

NProgress.configure({ showSpinner: false });

parent

specify this to change the parent container. (default: body)

NProgress.configure({ parent: '#container' });

Customization

Just edit nprogress.css to your liking. Tip: you probably only want to find and replace occurrences of #29d.

The included CSS file is pretty minimal... in fact, feel free to scrap it and make your own!
