Development Web Design

Mastering web application development with angularjs

AngularJS is a client side model view controller (MVC) framework that written in JAVA. Build a single page web applications using the power of AngularJS. It is an open source JavaScript framework. Its goal is to develop model view controller based web applications and reduce the amount of JavaScript needed to make web application functional and AngularJS is a structural framework for dynamic web applications. AngularJS is built on the belief that declarative programming should be used to create user interfaces and also connect with software components while imperative programming is better than suited to the defining an application on the business logic.

AngularJS runs in a web browser and greatly help for developers to write modern, single page, Asynchronous Javascript and XML (AJAX) style web application. This is a general purpose framework, but it shines when used to write Create, Read, Update, Delete (CRUD) type web applications. It lets you use HyperText Markup Language (HTML) as your template language and also lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS use data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser and making it an ideal partner with any server technology. AngularJS used some views, controllers, and services are the basic ingredients of any AngularJS application.

While building a client side web application only AngularJS is not used. It handles all of the Document Object Model (DOM) and AJAX glue code you once wrote by hand and puts it in a well-defined structure. That makes AngularJS opinionated about how a CRUD (Create, Read, Update, Delete) application should be built. But while it is opinionated and it also tries to make sure that its opinion is just a starting point you can easily change it. AngularJS comes with the following out of the box:-

Things need to build a CRUD application in a cohesive set environment :- basic templating directives,form validation, data-binding, routing, deep-linking, reusable components and dependency injection.

Testability story :- Unit testing, end to end testing, mocks and test harnesses. Seed application with directory layout and test scripts as well as a starting point.

AngularJS include some design goals:-

1- To decouple the client side of an application from the server side. This allows for development work to progress in parallel, and also allows for reuse of both sides.

2- To decouple DOM manipulation from application logic and the difficulty of this is dramatically affected by the way the code is structured.

3-To provide structure for the journey of building an application from designing the user interface (UI), through writing the business logic used to testing.
