What is Angular JS Development ?
AngularJS is an open-source JavaScript framework developed by Google. AngularJS can create all the interactive elements we normally find on a website. The framework’s main objective is to help develop single-page applications.
Main Features of AngularJS
Data Binding
In an angular application, we don’t need to write separate code to perform the data binding functionality. By adding some snippets of code we can easily bind data from HTML control to application data. Any extra code is not written to bind with HTML control.
Architecture
An angular application is built using MVC architecture that stands for Model View and Controller. It separates the application into three parts model part, view part and controller part as per the components of MVC architecture. Using this, architecture presentation part, logic part and application data part is split into the separate section which allows managing of application in a very fluent manner.
Directives
View of angular JS, mix data from a model into Hyper Text Markup Language templates. Angular JS directives are used for the same purpose. It tells how to combine data into the HTML template. With the use of directive, we can provide extra functionality to our angular application. Angular provides a way to create custom directives too. There is a list of angular JS directives:
Not Browser Specific
Angular applications are not browser specific means there is no browser constraint on an angular application.
- It can run on all major browsers except internet explorer 8.0 and smartphones including Android and IOS based phones/tablets.
- It claims to support “CLASS A” browsers such as Chrome, Firefox, Safari, IE8, Android.
Code Less
- A programmer can write less and perform more functionalities with the same code.
- Filters in angular provide the functionality of write less do more. The various filters in angular are uppercase, lowercase, currency etc. You can use the filter and easily format the data.
Speed and Performance
Speed and performance of angular are faster because of three things:
- Code Generation – When you are writing code using angular, it converts your template into a highly optimized code that gives you an advantage of handwritten code with the productivity of framework.
- Universal – The first view of your application on .net, PHP, node.js and other servers that is till now dependent on HTML CSS for their front end serve using angular.
- Code Splitting – Its new component router loads angular app quickly. It provides the ability of automatic code splitting too. Therefore only that code is loaded which is requested to render the view.
Dependency Injection
- This built-in injection helps in developing the application easily as well as it is easy to understand.
- It helps an application easier to test.
- Whenever angular JS detect that you need a service then it immediately provides an instance for that.
- It allows you to ask for your dependencies rather than having to go look for them or making it by yourself.
Productivity
- Template – Template in the angular application allows a developer to create user interface quickly as it provides simple and powerful template syntax.
- Angular CLI – It is a command line tool. It starts building an application very fast. It adds components, tests it and then deploys it instantly.
- IDE – Intelligent code completion is possible through IDE. It will find instant errors and provides other feedbacks too.
Conclusion
Due to Angular JS features, it becomes the most popular JavaScript framework among developers for web application development. All this is possible because angular provides an easy and efficient way to a developer to create a single page web application. It can solve the time consumption and slow working issues. Therefore, angular is used in various applications such as PayPal, Netflix etc.
