What are the reasons to use AngularJS in web applications?

AngularJS is a structural frame-work for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's elements easily and shortly. AngularJS's data list and dependency injection exclude much of the code you would otherwise have to write And it all happens within the browser, making it an ideal match with any server technology. AngularJS is what HTML would have been, had it been designed for application. HTML is a great declarative language for static documents. It extends the capability of HTML by adding erected-in attributes and factors and also provides a capability to produce custom attributes using simple JavaScript. Angular is an open-source frame.

A complete client-side solution:

AngularJS isn't a single piece in the overall puzzle of making the customer- side of a web applications. It handles all of the DOM and AJAX glue code you onetime wrote by hand and puts it in a well- defined structure. This makes AngularJS opinionated about how a CRUD ( Build, Read, Update, Delete) operation should be made. But while it's opinionated, it also tries to make sure that its opinion is just a starting point you can fluently change. AngularJS Development comes with the following out-of-the-box:

• Everything you need to build CRUD apps in a cohesive set: Data-binding, basic templating directives, form validation, routing, deep-linking, reusable components and dependency injection.
• Test Ability story: Unit-testing, end-to-end testing, mocks and test harnesses.
• Seed application with directory layout and test scripts as initial points.

Libraries of AngularJS:

AngularStrap- AngularStrap provides a set of native directives that allow you to use web elements suchlike as modal, popovers etc handed by bootstrap in your AngularJS operation. It has no external dependences except the Bootstrap CSS styles. It also provides animation support through the ngAnimate module and corresponding animation classes like as fade, slide, flip etc. Angular Strap is one of the best modules if your UI has a stack of Angular.js and Bootstrap CSS!

Angular UI-bootstrap- Look like an Angular Strap, Angular UI-bootstrap provides a set of bootstrap elements in pure Angular JS with no dependency on jQuery or Bootstrap's JavaScript. The only one dependency is AngularJS and Bootstrap CSS. Developer have the option of choosing between the two Angular UI-bootstrap or Angular strap in their operation.

UI-router: Let's face it, the authorized router handed over by AngularJS only suffices for erecting simple application's, but lacks features needed by big and complex apps. UI-router is a strong routing library which turns your application's into a state machine. It providing states which are bound to views. Unlike the ng Route module, UI-router allows you to have parallel as well as nested views. These state may or may not have routes.

Angular Loading Bar- As the name implies, this directive provides a loading bar at the top of the screen, matching to the one you may have encountered on YouTube. What makes this library stand out from the rest is that it's fully automatic. You only have to include the JS and CSS file, inject the dependency, and the loading/ progress bar will show in your coming $ http call. Another important aspect is that it also provides many configurable options to developers.

AngularJS frees you from the following pains:

Registering Call Back's- Registering call back's clutters your code, making it hard to see the forest for the trees. Removing common boilerplate code such as call back's is a good thing. It vastly reduces the volume of JavaScript coding you have to do, and it makes it easier to see what your application's does.

Manipulating HTML DOM programmatically- Manipulating HTML DOM is a cornerstone of AJAX application, but it's cumbersome and error-prone. By declaratively describing how the UI should change as your applications state changes, you're freed from low- rank DOM manipulation tasks. Maximum application written with AngularJS never have to programmatically manipulate the DOM, although you can if you want to.

Marshaling data to and from the UI- CRUD operations make up the majority of AJAX application' tasks. The flow of marshaling data from the server to an internal object to an HTML form, allowing user to modify the form, validating the form, displaying validation's errors, returning to an internal model, and again back to the server, creates a lot of boilerplate code. AngularJS eliminates approximately all of this boilerplate, leaving code that describes the overall flow of the applications rather than all of the implementation details.

Writing tons of initialization code just to get started- Generally you need to write a lot of plumbing just to get a introductory "Hello World" AJAX app working. With AngularJS you can bootstrap your app fluently using services, which are bus- fitted into your applications in a Guice-like dependency-injection style. This allows you to get started developing features fast. As a benefit, you get full control over the initialization process in automated tests.

Benefits of AngularJS development:

1. Improved Design Architecture

Some of our application contain over 60 factors & its still easy to manage in spite of new developer's that join on the design. It gives an idea of the operation & its functionality & it come easy to detect the canons for the angular js developer in an easy manner too. So its a bettered & enhance design structure in the market!

2. Promotes Code Reusability

Developer can now re-use the codes or the factors of the codes written before in different applications therefore making Angular JS development a very unique frame.

3. Better Plug & Play Components

Still, you need to just copy & paste the same into a new onece! You're done! Its works magically! All assets can be available automagically! Its truly plug & play in Angular JS development, If you wish to add your existing factors in a new applications.

4. Faster operation development

The MVC architecture ensures that the applications development, testing & maintenance is fast & quick! It helps in enhancing the productivity of the developer too!

5. Handles Dependences

Dependencies injection is something Angular JS is famous for & it does it really well! It shines in two areas, namely testing & Single Page Applications ( SPA) design!

6. Allows Resemblant Development

You already know that AngularJS Development can handle dependencies & coupled with MVC architecture which allows faster applications development allows the developers to perform parallel applications development as well! This is where AngularJS score over other frameworks.
