What are Angular JS modules? – A Simple Demo

By | July 15, 2017

Angular JS modules means :

  • An AngularJS module defines an application.
  • The module is a container for the different parts of an application like controller, services, filters, directives etc.
  • The module is a container for the application controllers.
  • Controllers always belong to a module.

Angular JS Modules


Here we have a module named “MyApp” and controller for this module is “MyController”.
“MyApp” specifies an HTML element in which the application will run.

      <title>Angular JS Controller</title>
      <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
      <h2>AngularJS Module Demo</h2>
      <div ng-app="MyApp" ng-controller="MyController">
      	{{ firstName + " " + lastName }}
    var app = angular.module("MyApp", []);
      app.controller("MyController", function($scope){
      	$scope.firstName = "Coderz";
      	$scope.lastName = "Heaven";
      // You can write other functions below
      function demoFunction1(){
      	alert("This is a Demo Function")


You cannot write multiple controllers in one html page. Only the first one will work.
