Migration from MVC to Angular

Migration from JSP i.e. server-side template engine to client side requires a paradigm switch towards client-server architecture. AngularJS becomes a by default application that runs on its own on the web browser and communicates with the related backend services offered by MVC. The only similarity between MVC application and AngularJS are deployed in the common Java WAR file and the index files are presented as a JSP.

Application Structure

Spring, as well as Angular application, can be organized simultaneously. The creation of AngularJS is built within src/main/web app and there are certain essential files such as:

• •   Components/
• •   Images/
• •   Video/
• •   Plugins/
• •   Js/app.js

As per the feature-grouping method, all the resources are organized. The resource can also be grouped based on their respective types, for example, grouping controllers, services and then view in the namesake folder.

Certain JavaScript based package managers such as npm and bower can be used if you want to simplify your external dependency management. A folder with the name bower_components will be created by default while using bower where all dependent resources shall be installed. Then you ought to include them in the template. But for npm, JavaScript server side system tools such as Grunt can be used in order to manage the JavaScript server.

Conversion from JSP to Angular

Transforming the controllers is mandatory rather than forwarding the response to template engine so as to provide a view to a client. Rather services will be offered that would serialize in JSON data. While developing a client-server architecture, synchronized states ought to be managed. Authentication and testing are included while the conversion takes place.

The conversion may be daunting but is extremely rewarding as it creates a maintainable under interface. More responsive web design applications are being built due to the encouragement of client side views. However, AngularJS is lately grabbing a lot of attention and you can detect the reason after you use it.
