JarCastingAngular-filter 
Bunch of useful filters for AngularJS (with no external dependencies!)
Angular 2 version is now available: ng-pipes
Table of contents:
Get Started
(1) You can install angular-filter using 4 different methods:
- clone & build this repository
- via Bower: by running
$ bower install angular-filterfrom your terminal - via npm: by running
$ npm install angular-filterfrom your terminal - via cdnjs http://www.cdnjs.com/libraries/angular-filter
(2) Include angular-filter.js (or angular-filter.min.js) in your index.html, after including Angular itself.
(3) Add 'angular.filter' to your main module's list of dependencies.
When you're done, your setup should look similar to the following:
<!doctype html>
<html ng-app="myApp">
<head>
</head>
<body>
...
<script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.0/angular.min.js"></script>
<script src="bower_components/angular-filter/dist/angular-filter.min.js"></script>
...
<script>
var myApp = angular.module('myApp', ['angular.filter']);
</script>
...
</body>
</html>
Collection
concat
Concatenates an array/object into another one.
function MainController ($scope) {
$scope.array = [ {a: 1}, {a: 2} ];
$scope.object = {
0: {a: 3},
1: {a: 4}
};
}
<li ng-repeat="elm in array | concat:object">
{{ elm.a }}
</li>
<!--
result:
1 2 3 4
-->
<li ng-repeat="elm in object | concat:array">
{{ elm.a }}
</li>
<!--
result:
3 4 1 2
-->
unique
Remove duplicates from an array/object.
If a string is provided, it will filter out duplicates using the provided expression.
Usage: collection | unique: 'property'
aliases: uniq
function MainController ($scope) {

];
}
Ex: Filter by customer.id
<th>Customer list:</th>
<tr ng-repeat="order in orders | unique: 'customer.id'" >

Group name: {{ key }}
<ul>
<li ng-repeat="player in value">
player: {{ player.name }}
</li>
</ul>

defaults
defaultsFilter allows to specify a default fallback value for properties that resolve to undefined.
Usage: col in collection | defaults: fallback
$scope.orders = [
{ id:1, destination: { zip: 21908 }, name: 'Ariel M' },
{ id:2, name: 'John F' },
{ id:3, destination: { zip: 45841 } },
{ id:4, destination: { zip: 78612 }, name: 'Danno L' },
];
$scope.fallback = {
name: 'Customer name not available',
destination: { zip: 'Pickup' }
};
<li ng-repeat="order in orders | defaults: fallback">
<b>id:</b> {{ order.id }},
<b>name:</b> {{ order.name }},
<b>shipping address:</b> {{ order.destination.zip }}
</li>
<!--Results:
* id: 1, name: Ariel M, shipping address: 21908
* id: 2, name: John F, shipping address: Pickup
* id: 3, name: Customer name not available, shipping address: 45841
* id: 4, name: Danno L, shipping address: 78612
Note: defaultsFilter change the source object.
Why? if we don't change the source object, it actually means we're gonna return a new object (copy operation) on each digest cycle.
And it will cause adverse memory and performance implications.
How to avoid it? see below
//We copy it once, and it's really cheaper
$scope.ordersWithFallback = angular.copy($scope.orders);
<li ng-repeat="order in ordersWithFallback | defaults: fallback">
<!-- ..... -->
</li>
