angular-tiny-eventemitter

Tiny event emitter for Angular.JS.

Installation

Add angular-tiny-eventemitter to your project:

bower install --save angular-tiny-eventemitter

Add it to your HTML file:

<script src="bower_components/angular-tiny-eventemitter/dist/angular-tiny-eventemitter.min.js"></script>

Reference it as a dependency for your app module:

angular.module('myApp', ['rt.eventemitter']);

Usage

Simply inject it as a service:

angular.module('myApp').factory('MyType', function (eventEmitter) {
    function MyType(something) {
        this.value = something;
    }
    
    // Add event emitter methods to MyType.
    eventEmitter.inject(MyType);

    return MyType;
});

You can then use all the normal event emitter methods:

angular.module('myApp').controller('TestCtrl', function ($scope, MyType) {
    var thing = new MyType(123);

    function logTheEvent(arg1, arg2) {
        console.log('Got event: ' + arg1 + ', ' + arg2);
    }

    thing.on('event', logTheEvent);

    $scope.$on('$destroy', function () {
        // Remember to avoid memory leaks!
        thing.off('event', logTheEvent);
    });

    thing.emit('event', 4, 8);
});

Alternatively, you can pass a $scope as the first parameter to on() or once() and the listener will be automatically unregistered if the $scope is destroyed.

angular.module('myApp').controller('TestCtrl', function ($scope, MyType) {
    var thing = new MyType(123);

    function logTheEvent(arg1, arg2) {
        console.log('Got event: ' + arg1 + ', ' + arg2);
    }

    // Passing $scope will register a $destroy event for you.
    thing.on($scope, 'event', logTheEvent);

    thing.emit('event', 4, 8);
});
