Brief information about AngularJS

Posted by tib on May 11th, 2019

Angular JS is an open source JavaScript framework that's wont to build web applications. Angular Js is developed by Google.

It is a superb framework for building single part applications and line of business applications.

Advantage of AngularJS

There are plenty of JavaScript frameworks for building web applications. So, it's a genuine question, why to use Angular JS.

Following are the benefits of AngularJS over different JavaScript frameworks:

• Dependency Injection: Dependency Injection specifies a style pattern during AngularJS Training in Marathahalli which parts are given their dependencies instead of onerous secret writing them within the part.
• Two approach information binding: AngularJS creates a 2 approach data-binding between the choose component and also the order Prop model. Order Prop is then used because the input for the order by filter.
• Testing: Angular JS is meant in a approach that we can test right from the beginning. So, it's terribly simple to test any of its elements through unit testing and end-to-end testing.
• Model view Controller: In Angular JS, it's terribly simple to develop application during a clean MVC approach. You only need to split your application code into MVC elements i.e. Model, view and also the Controller.
• Directives, filters, modules, routes etc.

AngularJS MVC architecture

MVC stands for Model view Controller. It’s a software design pattern for developing web applications. It’s very hip as a result of it isolates the applying logic from the interface layer and supports separation of issues.

The MVC pattern is created of the following 3 parts:

1. Model: it's responsible for managing application information. It responds to the requests from view and to the directions from controller to update itself.
2. View: it's responsible for displaying all data or only some of data to the users. It also specifies the info in a specific format triggered by the controller's call to present the information. They’re script-based template systems like JSP, ASP, PHP and really simple to integrate with Ajax technology.
3. Controller: it's responsible to manage the relation between models and views. It responds to user input and performs interactions on the info model objects. The controller receives input, validates it, and then performs business operations that modify the state of the info model.

AngularJS data binding

Data binding could be a terribly helpful and powerful feature used Angular Training in Marathahalli with placement in software development technologies. It acts as a bridge between the view and business logic of the applying.

AngularJS follows Two-Way data binding model.

One-Way data binding

The one-way data binding is an approach wherever a value is taken from the data model and inserted into an HTML component. There’s no way to update model from view. it's utilized in classical template systems. These systems bind data in just one direction.

Two-Way data binding

Data-binding in Angular apps is that the automatic synchronization of data between the model and look at parts.

Data binding allows you to treat the model because the single-source-of-truth in your application. The view could be a projection of the model in the least times. If the model is modified, the view reflects the change and the other way around.

AngularJS Directives

AngularJS facilitates you to increase HTML with new attributes. These attributes are known as directives.

There is a group of built-in directive in AngularJS that offers practicality to your applications. You can also outline your own directives.

Directives are special attributes beginning with ng- prefix. Following area unit the foremost common directives:

• ng-app: This directive starts an AngularJS Application.
• ng-init: This directive initializes application information.
• ng-model: This directive defines the model that's variable to be utilized in AngularJS.
• ng-repeat: This directive repeats HTML parts for every item during a collection.
