Using Modules to Define AngularJS Components


It is required to define an Angular JS Module while you creating it. There is a method angular.module which is used when we want to define an Angular JS Module. The angular.module method returns a Module object that provides access to the most important features that AngularJS provides via the properties and methods. The module method supports the three arguments described below, although it is common to use only the first two.

  • name The name of the new module
  • requires The set of modules that this module depends on
  • config The configuration for the module, equivalent to calling the Module.config method

Following are The Members of the Module Object, which is used in Angular JS Module creation.

  • animation(name, factory) Supports the animation feature
  • config(callback) Registers a function that can be used to configure a module when it is loaded.
  • constant(key, value) Defines a service that returns a constant value
  • controller(name, constructor) Creates a controller.
  • directive(name, factory) Creates a directive, which extends the standard HTML vocabulary.
  • factory(name, provider) Creates a service.
  • filter(name, factory) Creates a filter that formats data for display to the user.
  • provider(name, type) Creates a service.
  • name Returns the name of the module.
  • run(callback) Registers a function that is invoked after AngularJS has loaded and configured all of the modules.
  • service(name, constructor) Creates a service.
  • value(name, value) Defines a service that returns a constant value.
  • .

The methods defined by the Module object fall into three broad categories: those that define components for an AngularJS application, those that make it easier to create those building blocks, and those that help manage the AngularJS life cycle. I’ll start by introducing the building blocks and then talk about the other features that are available.

As this article is also a part of Concepts while working with Angular JS Application . So, you must read other tutorials in order to complete understanding to developing Angular JS Application. Since, we are going to learn several concepts. That's why I have broken this article into several small article. Which allow us to easily understand several Angular JS features and concepts. Following are the list of articles.

Problems Solutions
Create an AngularJS module. Use the angular.module method.
Set the scope of a module. Use the ng-app attribute.
Define a controller. Use the Module.controller method.
Apply a controller to a view. Use the ng-controller attribute.
Pass data from a controller to a view. Use the $scope service.
Define a directive. Use the Module.directive method.
Define a filter. Use the Module.filter method
Use a filter programmatically. Use the $filter method.
Define a service. Use the Module.service, Module.factory, or Module.provider method.
Define a service from an existing object or value. Use the Module.value method.
Add structure to the code in an application. Create multiple modules and declare dependencies from the module referenced by the ng-app attribute.
Register functions that are called when modules are loaded. Use the Module.config and Module.run methods.

Summary: You should read above mentioned articles in order to completely understanding to developing an Angular JS application. This article is a part of Concepts while working with Angular JS Application, which is divided in to pieces of tutorials in order to understand easily. I hope you will like this article and find it useful.
