PACE
====
[![Latest Release](https://img.shields.io/github/tag/CodeByZach/pace.svg?label=version)](https://github.com/CodeByZach/pace/releases/latest)
<a href="https://eager.io/app/kYKTiQjoVjQk/install?source=button">
<img src="https://install.eager.io/install-button.png" border="0" width="126">
</a>
An automatic web page progress bar.
Include [pace.js](https://raw.github.com/HubSpot/pace/v1.0.2/pace.min.js) and a [theme](http://github.hubspot.com/pace/docs/welcome/) of your choice to your page and you are done!
### [Demo](https://codebyzach.github.io/pace/)
### [Documentation](https://codebyzach.github.io/pace/docs/)
We also have a [Wordpress Plugin](https://wordpress.org/plugins/pace).
Include [pace.js](https://raw.github.com/CodeByZach/pace/master/pace.min.js) and the
[theme](https://codebyzach.github.io/pace/) css of your choice on your page
(as early as is possible), and you're done!
Pace will automatically monitor your Ajax requests, event loop lag, document ready state and elements on your page to decide on the progress.
Pace will automatically monitor your ajax requests, event loop lag, document
ready state, and elements on your page to decide the progress. On ajax navigation
it will begin again!
If you use AMD or Browserify, require pace.js and call `pace.start()` as early in the loading process as is possible.
### [Demo](http://github.hubspot.com/pace/docs/welcome/)
Example
-------
### [Documentation](http://github.hubspot.com/pace/)
### Example
```html
<head>
<script src="/pace/pace.js"></script>
<link href="/pace/themes/pace-theme-barber-shop.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/pace/1.2.3/pace.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/pace/1.2.3/pace-theme-default.min.css" rel="stylesheet" />
</head>
```
Configuration
-------------
Pace is fully automatic, no configuration is necessary to get started.
If you would like to make some tweaks, here's how:
You can set `window.paceOptions` before bringing in the file:
```javascript
paceOptions = {
// Disable the 'elements' source
elements: false,
// Only show the progress on regular and ajax-y page navigation,
// not every request
restartOnRequestAfter: false
}
```
You can also put options on the script tag:
```html
<script data-pace-options='{ "ajax": false }' src='pace.js'></script>
```
If you're using AMD or Browserify, you can pass your options to `start`:
```javascript
define(['pace'], function(pace){
pace.start({
document: false
});
});
```
Themes
------
Pace includes a bunch of [themes](https://codebyzach.github.io/pace/)
to get you started. Just include the appropriate css file. Send us a PR with
any interesting themes you create.
If you have minor styling changes and don't want to extend theme css, you can add custom class names to
the progress bar using the "className" option:
```javascript
paceOptions = {
className: 'my-custom-class'
}
```
Collectors
----------
Collectors are the bits of code which gather progress information. Pace includes four default collectors:
- Ajax
Monitors all ajax requests on the page
- Elements
Checks for the existance of specific elements on the page
- Document
Checks the document readyState
- Event Lag
Checks for event loop lag signaling that javascript is being executed
They can each be configured or disabled through configuration options of the same name.
```javascript
paceOptions = {
ajax: false, // disabled
document: false, // disabled
eventLag: false, // disabled
elements: {
selectors: ['.my-page']
}
};
```
Add your own classes to `paceOptions.extraSources` to add more sources. Each source should either
have a `.progress` property, or a `.elements` property which is a list of objects with
`.progress` properties. Pace will automatically handle all scaling to make the progress
changes look smooth to the user.
Elements
--------
Elements being rendered to the screen is one way for us to decide that the page has been
rendered. If you would like to use that source of information (not required at all),
specify one or more selectors. You can comma separate the selectors to propertly handle
error states, where the progress bar should disappear, but the element we are looking for
may never appear:
```javascript
paceOptions = {
elements: {
selectors: ['.timeline, .timeline-error', '.user-profile, .profile-error']
}
}
```
Pace will consider the elements test successful when each selector matches something. For
this example, when either `.timeline` or `.timeline-error` exist, and either `.user-profile`
or `.profile-error` exist.
Restart Rules
-------------
Most users want the progress bar to automatically restart when a pushState event occurs
(generally means ajax navigation is occuring). You can disable this:
```javascript
paceOptions = {
restartOnPushState: false
}
```
You can also have pace restart on every ajax request which lasts longer than x ms. You'll want to
disable this if you make ajax requests the user doesn't need to know about, like precaching:
```javascript
paceOptions = {
restartOnRequestAfter: false
}
```
You can always trigger a restart manually by calling `Pace.restart()`
See [the source](https://github.com/CodeByZach/pace/blob/master/pace.js) for a full list of options.
API
---
Pace exposes the following methods:
- `Pace.start`: Show the progress bar and start updating. Called automatically if you don't use AMD or CommonJS.
- `Pace.restart`: Show the progress bar if it's hidden and start reporting the progress from scratch. Called automatically
whenever `pushState` or `replaceState` is called by default.
- `Pace.stop`: Hide the progress bar and stop updating it.
- `Pace.track`: Explicitly track one or more requests, see Tracking below
- `Pace.ignore`: Explicitly ignore one or more requests, see Tracking below
Events
------
Pace fires the following events:
- `start`: When pace is initially started, or as a part of a restart
- `stop`: When pace is manually stopped, or as a part of a restart
- `restart`: When pace is restarted (manually, or by a new AJAX request)
- `done`: When pace is finished
- `hide`: When the pace is hidden (can be later than `done`, based on `ghostTime` and `minTime`)
You can bind onto events using the `on`, `off` and `once` methods:
- `Pace.on(event, handler, [context])`: Call `handler` (optionally with context) when `event` is triggered
- `Pace.off(event, [handler])`: Unbind the provided `event` and `handler` combination.
- `Pace.once(event, handler, [context])`: Bind `handler` to the next (and only the next) incidence of `event`
Tracking
--------
By default, Pace will show any ajax requests which begin as a part of a normal or ajax-y page load, or which last longer than
500ms.
You can disable all ajax tracking by setting `ajax` to false:
```javascript
Pace.options = {
ajax: false
}
```
You can disable ajax tracking except on page navigation by setting `restartOnRequestAfter` to false:
```javascript
Pace.options = {
restartOnRequestAfter: false
}
```
You can manually disable tracking for a specific request or requests by triggering them within a `Pace.ignore` callback:
```javascript
Pace.ignore(function() {
$.ajax(...)
});
```
You can force the progress bar to be shown for a specific request by triggering them within a `Pace.track` callback:
```javascript
Pace.track(function() {
$.ajax(...)
});
```
You can also ignore URLs based on a pattern:
```javascript
Pace.options = {
ajax: {
ignoreURLs: ['some-substring', /some-regexp/]
}
}
```
Dependencies
------------
None!
Support
-------
Pace is designed to support IE8+ (standards mode), FF 3.5+, Chrome, Safari 4+, Opera 10.5+, and all modern
mobile browsers. If you run into a compatibility issue, or can make a case for supporting something else,
please create an issue.
Size
----
pace.js is 4kb minified and gzipped. The themes vary between 0.5 and 4kb.
Issues
------
We have obviously not tested this on every website. If you run into an issue, or find a way the automatic
detection could be better, please [create an Issue](https://github.com/CodeByZach/pace/issues/new). If you can include a test case, that's even better.
