What is mvc architecture

These actions require the model to be updated, so the input is sent to the controller, which then manipulates the model as appropriate, which then sends updated data to the view. You might however also want to just update the view to display the data in a different format, e.

In this case the controller could handle this directly without needing to update the model. As a web developer, this pattern will probably be quite familiar even if you've never consciously used it before. Your data model is probably contained in some kind of database be it a traditional server-side database like MySQL, or a client-side solution such as IndexedDB [en-US].

In this article, we will learn about the MVC framework, its benefits, and how to develop efficient software applications. A Framework is a skeleton solution it gives the outline in which a specific element must be plugged to establish a solid solution. They are made up of a set of related classes that can be specialized to implement an application. Software architecture is the way a system is organized. This organization covers all components, how they interact, the operating environment, and the software design principles.

Currently, MVC is the top-ranked software architecture that developers are using. It constitutes three interconnected components. These components are:. The model is the layer that keeps data for the application. The layer is responsible for storing and retrieving data from the database, and it is also responsible for validating the data. For example, if you want to create a new user, you will have to create a new user model and save it to the database.

For instance, if you want to create a user view, you will have to create UI components that the user interacts with, such as a login form in an easy-to-understand format. The controller is the logic layer of the application. It links the view and the model. The controller receives the request for the application and passes it to the model to send and receive data. Essentially, the controller is the link between the view and model. Through getter and setter functions, the controller pulls data from the model and initializes the views.

JavaScript has grown in popularity, and it's taken over the backend in recent years. More and more full-blown JavaScript applications have opted for the MVC architecture pattern in one way or another. Frameworks come and go, but what has been constant are the concepts borrowed from the MVC architecture pattern.

Managing the frontend and backend in smaller, separate components allows for the application to be scalable, maintainable, and easy to expand.

Build your own web apps from scratch Learn everything you need to know to build JavaScript web apps all in one place. What is MVC Architecture? View: Graphical User Interface The view is a visual representation of the data- like a chart, diagram, table, form. Controller: Brains of the application. Web App as a MVC. Separation of Concerns MVC design allows for Separation of Concerns - dividing the logic up between the 3 buckets, so that each bucket can act independently.

Loosely Coupled Loosely coupled means that each piece: the model, view and controller, act independently of eachother. MVC with User Action. Model In our Game of Thrones example the model is the fake database that lists the houses and characters.

Controller The controller is the brains of our application - the JavaScript that handles the click event. What to learn next Congratulations on completing your first look into MVC architecture.
