Changes nprogress to use multiple progress bars overlaid. WARNING: this was just a test to see how it would look, needs some developer love if you really want to use it.
Slim progress bars for Ajax'y applications. Inspired by Google, YouTube, and Medium.
Add nprogress.js and nprogress.css to your project as well as please.js.
<script src='vendor/please.js'></script>
<script src='nprogress.js'></script>
<link rel='stylesheet' href='nprogress.css'/>
NProgress is available via bower and npm.
$ bower install --save nprogress
$ npm install --save nprogress
Simply call start()
and done(id)
to control the progress bar.
NProgress.start() - returns id;
NProgress.done(id);
Using Turbolinks or similar? Ensure you're using Turbolinks 1.3.0+, and use this: (explained here)
$(document).on('page:fetch', function() { curProgressId = NProgress.start(); });
$(document).on('page:change', function() { NProgress.done(curProgressId); });
$(document).on('page:restore', function() { NProgress.remove(curProgressId); });
-
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
.
Percentages: To set a progress percentage, call .set(n)
, where n is a
number between 0..1
.
NProgress.set(id, 0.0); // Sorta same as .start()
NProgress.set(id, 0.4);
NProgress.set(id, 1.0); // Sorta same as .done()
Incrementing: To increment the progress bar, just use .inc(id)
. This
increments it with a random amount. This will never get to 100%: use it for
every image load (or similar).
NProgress.inc(id);
If you want to increment by a specific value, you can pass that as a parameter:
NProgress.inc(id, 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(id, true);
Get the status value: To get the status value, use .status
Changes the minimum percentage used upon starting. (default: 0.08
)
NProgress.configure({ minimum: 0.1 });
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>"
});
Adjust animation settings using ease (a CSS easing string)
and speed (in ms). (default: ease
and 200
)
NProgress.configure({ ease: 'ease', speed: 500 });
Turn of the automatic incrementing behavior by setting this to false
. (default: true
)
NProgress.configure({ trickle: false });
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 });
Turn off loading spinner by setting it to false. (default: true
)
NProgress.configure({ showSpinner: false });
specify this to change the parent container. (default: body
)
NProgress.configure({ parent: '#container' });
Just edit nprogress.css
to your liking. Tip: you probably only want to find
and replace occurances of #29d
.
The included CSS file is pretty minimal... in fact, feel free to scrap it and make your own!
