Model, view and controller or MVC is a popular trilateral development architecture largely used for web applications developments. The MVC pattern architecture provides us with the idea of separation of concern and gives us the idea to implement the separation of concern among the model, view, and controller classes within applications.
Model- The Model classes can be harnessed to implement the logic of data domains. The classes can be used to retrieve, insert, or update the data into the database associated with the web application.
View- Views can be used to prepare the interface of your web application. This lets users interact with the application when they use the interface.
Controller- One can use Controller classes in order to respond to the user’s requests. These classes perform the users requested actions. These classes work with model classes and choose the apt view which should be disclosed to the user heeding the user requests.
When should one use MVC pattern architecture?
MVC helps us to implement a test-driven development approach, where automated test cases are implemented before one writes the code. Such unit test cases help us define and verify requirements of new, updated code before writing it. If one makes an application with satisfactory amount of deliberate stimulation on the client side to refuse to go along with JavaScript alone. If one is developing an application which has tremendous lifting on the server side and minimal communication on the client side, in that case, the usage of MVC pattern architecture should be avoided. Instead one should use simple setup such as web-based form model.
One should use MVC architecture
i. When the application needs asynchronous communication on the backend.
ii. Whether the application has a functionality that results in not to reload a full page. This is just like commenting on a post while using Facebook or scrolling infinitely through the feeds.
iii. When the manipulation of data is majorly on the client side or the browser side rather than server side.
iv.If the similar data is being delivered in different ways on a single page (navigation).
v. If you feel that the application has insignificant connections which needs to be used to modify data like, button, switches etc.
Advantages of MVC architecture
a. MVC architecture helps us to control the complexity of application by dividing it into three components i.e. model, view and controller.
b. MVC does not use server-based forms, that’s why it is ideal for those developers who want full control over their application behavior.
c. Test driven development approach is supported by MVC architecture.
d. MVC use front controller pattern. Front controller pattern handles the multiple incoming requests using single interface (controller). Front controller provides centralized control. We need to configure only one controller in web server instead of many.
e. Front controller provides support rich routing communications to design our web application.
Features of MVC framework
When we divide the logic of our application into three different tasks viz, input logic, business logic, and interface logic, testing each of these components separately will become easy. The testability is quick and flexible, since one can use their choice of unit testing framework that is compatible with MVC framework.
Since it is an extensible and pluggable framework, the development team can design the components of the application in a way where they are easily replaceable or moldable to suit the needs. During the development, one can plug view engine, URL routing strategy, action method constraint serialization.
Also, instead of using file name extensions, MVC supports URL naming patterns that is conclusive for search engine optimization--SEO and representational state transfer (REST) addressing.
Other frameworks of MVC like ASP.NET MVC enables built in features like form authentication, session management, transactional business logic, web application security, object relational mapping, localization membership and roles and, URL authorization.
Let’s look at some other popular frameworks that are available today:
I. Backbone.js- Backbone.js provides flexibility, has to meet uncertain requirements, and have to accommodate changes during the development phase.
II. Angular.js- It provides reliability and stability in application development. Hire Angular.js developers if you want extensive testing for your application.
Iii. Knockout.js- Useful in making complex and dynamic interface application.
IV. Ember.js- If you want your application should interact with JSON API, then Ember.js is the best choice.
V. Node.js- It helps you create quick, robust network applications which can tackle parallel connections with increased output. You can hire Node.js developers who can program your web applications crafting them using JavaScript which implies that the silos that were present between the frontend and the backend developers are split entirely thereby, increasing the effectiveness of the web development process.
Conclusion
There are numerous enterprises opting for the development of web applications which is based on MVC architecture in order to rake in maximum benefits out of this modern architecture.
