AngularJS Cheatsheet

AngularJS is an amazingly simple, powerful framework and something you should all learn. The simplicity and power of this framework should make any developer excited. This is a cheatsheet to remind me of the general process of creating a typical AngularJS app.

This document is intended for developers familiar with AngularJS. If non of this makes sense to you then you should first learn the core concepts of AngularJS.

Declaring a new Module

var app = angular.module("myApp", []);

Once a new module is defined you can attach it to any element within the DOM.

<body ng-app="myApp"> ... </body>

App Controller

Used to control the data used in an application. Controllers are regular JavaScript Objects.

myApp.controller('ControllerName', ['$scope', function($scope) {
    $scope.greeting = 'Hola!';
    // additional data is defined here.

Once a controller is declared you can attach it with the ng-controller directive.

<div ng-controller="ControllerName">
  {{ greeting }}

you can also use arrays to store objects inside the app controller.

myApp.controller('People', ['$scope', function($scope) {
    $scope.persons = [
          name: 'Matthew',
          occupation: 'Web Developer',
          age: 27
          name: 'Simon',
          occupation: 'Mechanic',
          age: 27
          name: 'Luke',
          occupation: 'Builder',
          age: 27

Repeatable Blocks

AngularJS has a neat way to convert arrays into repeatable blocks of HTML with ng-repeat. This is similar in principal to foreach loops.

<div class="main" ng-controller="People">
      <div class="container">        
        <div class="people row" ng-repeat="person in persons">
            <div class="item col-md-9">
                <h3 class="name">{{ }}</h3>
                <p class="occupation">{{ person.occupation }}</p>
                <p class="age">{{ person.age }}</p>


AngularJS directives are extended HTML attributes with the prefix ng-. AngularJS has a number of built in directives.

  • ng-app – defines the root HTML element.
  • ng-controller – defines the application controller.
  • ng-init – defines initial values.
  • ng-model – binds the value of HTML controls (input, select, textarea) to application data.
  • ng-repeat – used to clone HTML blocks. Similar to a foreach loop.
  • ng-click – defines an Angular click event.
  • ng-src – used to correctly return URLs. Replaces src.

You can also define a custom directive like so.

app.directive('directiveName', function() { 
    return { 
        restrict: 'E', 
        scope: { 
            info: '=' 
        templateUrl: 'pathToTemplate.html'
