NProgress
Minimalist progress bar
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[npm].
$ npm install --save @logdna/nprogress
Basic usage
Simply call start()
and done()
to control the progress bar.
NProgress.start();
NProgress.done();
Turbolinks (version 5+)
Ensure you're using Turbolinks 5+, and use this: (explained here)
$(document).on('turbolinks:click', function() {
NProgress.start();
});
$(document).on('turbolinks:render', function() {
NProgress.done();
NProgress.remove();
});
Turbolinks (version 3 and below)
Ensure you're using Turbolinks 1.3.0+, and use this: (explained here)
$(document).on('page:fetch', function() { NProgress.start(); });
$(document).on('page:change', function() { NProgress.done(); });
$(document).on('page:restore', function() { NProgress.remove(); });
Pjax
Try this: (explained here)
$(document).on('pjax:start', function() { NProgress.start(); });
$(document).on('pjax:end', function() { NProgress.done(); });
Ideas
Add progress to your Ajax calls! Bind it to the jQuery
ajaxStart
andajaxStop
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 });
trickleSpeed
Adjust how often to trickle/increment, in ms.
NProgress.configure({ trickleSpeed: 200 });
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!
