Get angular-spinner

• via npm: by running $ npm install angular-spinner from your console

Include angular-spinner.js in your application.

import 'angular-spinner';

OR:

require('angular-spinner');

OR by picking one of the following files (minified/not-minified):

<script src="node_modules/angular-spinner/dist/angular-spinner.js"></script>
<script src="node_modules/angular-spinner/dist/angular-spinner.min.js"></script>

Add the module angularSpinner as a dependency to your app module:

var myapp = angular.module('myapp', ['angularSpinner']);

You can now start using the us-spinner directive to display an animated spinner. For example :

<span us-spinner></span>

You can also pass spinner options, for example:

<span us-spinner="{radius:30, width:8, length: 16}"></span>

Possible configuration options are described in the spin.js homepage.

You can direct the spinner to start and stop based on a scope expression, for example:

<span us-spinner="{radius:30, width:8, length: 16}" spinner-on="showSpinner"></span>

You can use usSpinnerConfigProvider to configure default options for all spinners globally. Any options passed from a directive still override these.

myapp.config(['usSpinnerConfigProvider', function (usSpinnerConfigProvider) {
    usSpinnerConfigProvider.setDefaults({color: 'blue'});
}]);

Themes provide named default options for spinners. Any options passed from a directive still override these.

myapp.config(['usSpinnerConfigProvider', function (usSpinnerConfigProvider) {
    usSpinnerConfigProvider.setTheme('bigBlue', {color: 'blue', radius: 20});
    usSpinnerConfigProvider.setTheme('smallRed', {color: 'red', radius: 6});
}]);

<span us-spinner spinner-theme="smallRed"></span>

<button ng-click="startSpin()">Start spinner</button>
<button ng-click="stopSpin()">Stop spinner</button>

<span us-spinner spinner-key="spinner-1"></span>

The usSpinnerService service let you control spin start and stop by key. Whenever the key is not specified all the spinner will be affected (Start/Stop all spinners):

app.controller('MyController', ['$scope', 'usSpinnerService', function($scope, usSpinnerService){
    $scope.startSpin = function(){
        usSpinnerService.spin('spinner-1');
    }
    $scope.stopSpin = function(){
        usSpinnerService.stop('spinner-1');
    }
}]);

Note that when you specify a key, the spinner is rendered inactive. You can still render the spinner as active with the spinner-start-active parameter :

<span us-spinner spinner-key="spinner-1" spinner-start-active="true"></span>

spinner-start-active is ignored if spinner-on is specified.

The spinner-key will be used as an identifier (not unique) allowing you to have several spinners controlled by the same key :

<span us-spinner spinner-key="spinner-1"></span>
<span us-spinner spinner-key="spinner-2"></span>

... random html code ...

<!-- This spinner will be triggered along with the first "spinner-1" -->
<span us-spinner spinner-key="spinner-1"></span>
