Minimalist progress bar

top progress

install

Add [rayprogress.js] and [progress.css] to your project.

<script src='ray-progress.js'></script>
<link rel='stylesheet' href='progress.css'/>

  $ npm install --save ray-progress

Basic usage

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

import RProgress from 'ray-progress';
RProgress.start();
RProgress.done();

Turbolinks (version 5+)

Ensure you're using Turbolinks 5+, and use

$(document).on('turbolinks:click', function() {
  RProgress.start();
});
$(document).on('turbolinks:render', function() {
  RProgress.done();
  RProgress.remove();
});

Turbolinks (version 3 and below)

Ensure you're using Turbolinks 1.3.0+, and use

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

Pjax

$(document).on('pjax:start', function() { RProgress.start(); });
$(document).on('pjax:end',   function() { RProgress.done();  });

simple

• 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.

RProgress.set(0.0);     // Sorta same as .start()
RProgress.set(0.4);
RProgress.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).

RProgress.inc();

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

RProgress.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)

RProgress.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)

RProgress.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.

RProgress.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)

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

trickle

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

RProgress.configure({ trickle: false });

trickleSpeed

Adjust how often to trickle/increment, in ms.

RProgress.configure({ trickleSpeed: 200 });

showSpinner

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

RProgress.configure({ showSpinner: false });

parent

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

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

Custom

Just edit progress.css to your liking.
