ngActivityIndicator

Simple application preloader animation provider for Angular.js applications.

ngActivityIndicator is small, all-in-one solution, customizable through themes and dependant only on Angular.js.

Demo

Install

You can download all necessary ngActivityIndicator files manually or install it with bower:

bower install ngActivityIndicator

Usage

You need to include ngActivityIndicator.js and ngActivityIndicator.css (as minimal setup) to your project and then you can start using $activityIndicator service wherever you want - inside your directives, controllers or services. For example in controllers:

var app = angular.module('exampleApp', ['ngActivityIndicator']);
 
app.controller('MainCtrl', ['$activityIndicator', '$timeout',
    function ($activityIndicator, $timeout) {
        $activityIndicator.startAnimating();
        $timeout(function () {
            $activityIndicator.stopAnimating();
        }, 3000);
    }
]);

You can use ngActivityIndicator directive to show one of built-in animated views or you are able to create your own preloader in html, style it with CSS and simply show/hide it:

<body>
    <div ng-show="AILoading" class="your-preloader"></div>
    <div ng-hide="AILoading" ng-view></div>
</body>

Also this service can be easily used with loading SVG concept by Brett Jackson. But be aware of limited browser SVG support and user experience issues with perceptual loading time - http://caniuse.com/svg-smil.

Or you can use preloader styles from Luke's https://github.com/lukehaas/css-loaders as well.

API

API is highly inspired by Objective-C UIActivityIndicatorView class from UIKit framework.

startAnimating()

Start preload animation by setting $rootScope.AILoading to true.

stopAnimating(delay)

Stop animating preloader by setting $rootScope.AILoading to false.

isAnimating()

Check whether activity indicator is animating or not.

setActivityIndicatorStyle()

There are several styles built-in. Style by default is CircledGrey, you can change it by setting the value string on $activityIndicatorProvider, example:

angular.module('yourModule', ['ngActivityIndicator'])
    .config(['$activityIndicatorProvider', function ($activityIndicatorProvider) {
        $activityIndicatorProvider.setActivityIndicatorStyle('SpinnerDark');
    }]);

Directive

Module is shiped with helpful directive. It is called as ngActivityIndicator and can behave differently based on the tag or restrict it's used with.

When it's added to <body> tag, it adds relevant preloader into the app, shows and hides ng-view while animating. It's recommended and the most common use-case, example:

<!-- Indicator is injected into the DOM automatically -->
<body ng-activity-indicator>
 
    <!-- ngView is shown/hidden automatically -->
    <div ng-view></div>
</body>

If you prefer to manage what to show on preloading mode by yourself, just use it as an element or attribute. Directive will handle animation status automaticly, example:

<body>
    <!-- it is shown/hidden automatically -->
    <div ng-activity-indicator class="center"></div>
 
    <!-- show/hide elements based on $rootScope.AILoading property -->
    <div ng-hide="AILoading" class="some-wrapper"></div>
</body>

You can also override preloader style by adding it's name as directive value:

<div ng-activity-indicator="CircledDark"></div>

Skip ngShow

Sometimes it's useful to control indicator show/hide behavior by your own $scope (for example if you have multiple loaders inside one view). In this case there is additional attribute for directive:

skip-ng-show="[yes/no]"

It's easy to use, just add it on the activity indicator directive:

<div ng-show="myLoadingConditional" ng-activity-indicator skip-ng-show="yes"></div>

This will ends up in skipping ng-show="AILoading" directive on ngActivityIndicator element and will add ability to control loader presence by myLoadingConditional.

Built-in styles

You're able to choose what indicator suites you most within default ones or create your own.

List of style names:
  • CircledWhite / CircledGrey (default) / CircledDark
  • DottedWhite / DottedGrey / DottedDark
  • SpinnerWhite / SpinnerGrey / SpinnerDark
