Changes history you can find here

Main features

• Independent from $digest cycle (don't run unnecessary cycles)
• Can place many progress bars on one page
• Full control of each bar
• Custom progress-bar container
• Simple customization via css

Demo

You can see demo on this page

Installation

• Via bower (preferred way)

bower install --save pg.progress-bars

• Download zip package

Usage

1. Add module as dependency to your app:

angular.module('your-app', ['pg.progress-bars']);

2. Add progress bar directive to template:

<pg-progress-bar name="some-name"></pg-progress-bar>

3. Now you can inject ProgressBarsStorage service and get full control of your progress bars.
   Just get it by name:

var progressBar = ProgressBarsStorage.get('some-name');

progressBar.start();

setTimeout(function () {
    //async result
    progressBar.done();
}, 1500);

4. Default progress bar styles you can find in demo/styles.css (at the bottom of file).

Module's components

• progressBar directive - directive for adding progress bar to the page.
• ProgressBarFactory - main progress bar constructor.
• ProgressBarsSettings provider provider - allows to define base classes for progress bar
• ProgressBarsStorage service - all directives registers in this storage.

progressBar directive

Directive will be replaced by its template. For customization different progress bars you can add classes to it. It will be merged with template classes.

Usage

<pg-progress-bar name="main"></pg-progress-bar>

Directive params

Name	Binding Type	Default value	Description	Example
name	@		You must specify name of each progress bar for get it then through ProgressBarsStorage	<pg-progress-bar name="main"></pg-progress-bar>
minimum	@	8	Minimum value from which started progress bar	<pg-progress-bar name="main" minimum="25"></pg-progress-bar>
speed	@	250	Speed of each width increasing	<pg-progress-bar name="main" speed="500"></pg-progress-bar>
trickleRate	@	2	Multiplier of each increasing of width when progress bar is running	<pg-progress-bar name="main" trickle-rate="5"></pg-progress-bar>
trickleSpeed	@	300	Multiplier of each increasing of width when progress bar is running	<pg-progress-bar name="main" trickle-rate="5"></pg-progress-bar>
animation	@	'ease-out'	Type of css animation	<pg-progress-bar name="main" animation="linear"></pg-progress-bar>

Base progress bar template structure

<div class="progress__container"><div class="progress__bar"></div></div>

Full example

<pg-progress-bar
    name="main"
    minimum="15"
    speed="350"
    trickle-rate="4"
    trickle-speed="400"
    animation="linear">
</pg-progress-bar>

ProgressBar factory

Don't use it directly, it will be constructed when you use html <pg-progress-bar></pg-progress-bar> directive. Then you can get instance of ProgressBar class from ProgressBarsStorage and use methods.
You can combine method calls to chain (only for non-get methods). Example:

progressBar.start().inc().inc();

Public methods description

Method	Params	Returns	Description	Example
start		this	Start progress bar. It will constantly increase its width value prior to calling done or stop method	progressBar.start()
stop		this	Stop increasing value of width	progressBar.stop()
done		this	Complete progress bar work	progressBar.done()
get		{number} - width value	Get current width of progress bar	progressBar.get()
set	{number} value	this	Set width of progress bar	progressBar.set(45)
inc	{number} [value]	this	Increase value of progress bar to specified value or random value if it not specified	progressBar.inc(); progressBar.inc(15)
isInProgress		{boolean} - is running value	Whether running or not progress bar now	progressBar.isInProgress()

ProgressBarsSettings provider

You can use this methods only in config block. All methods returns this so you can chaining methods calls. For default values I used BEM methodology class naming convention.

Method	Params	Default Value	Description	Example
setContainerClass	{string} className	progress__container	Set container's class.	ProgressBarsSettingsProvider.setContainerClass('progress-container')
setBarClass	{string} className	progress__bar	Set progress bar's class.	ProgressBarsSettingsProvider.setContainerClass('progress-bar')
setShowingClass	{string} className	progress__container_showing	Set container's class which will be added when progress bar is running.	ProgressBarsSettingsProvider.setShowingClass('progress-bar-showing')

ProgressBarsStorage service

This service has only one public method: get. With this method you can get ProgressBar instance and use its methods.
Example:

var mainProgressBar = ProgressBarsStorage.get('main');
var completed = false;

mainProgressBar.start();

var getInterval = setInterval(function () {
    if (completed) {
        clearInterval(getInterval);
    }

    console.log(mainProgressBar.get());
}, 1000);

setTimeout(function () {
    mainProgressBar.done();
    completed = true;
}, 5000);
