WHAT IS MVC ARCHITECHTURE ?

MVC stands for MODEL - VIEW - CONTROLLER and it is an architecture that seperates different logics of an application. The 3 different logics namely the Model, the View and the Controller have different roles in an application which will be discussed below

In short, a View is something a user sees when they log on to the website. View gets generated when a Controller communicates with a Model and sends data recieved . 
When a user opens browser and types a website address into the search bar and hits ENTER, the request gets sent to the CONTROLLER gathers the required data needed for the route using the MODEL and then throws the data to the VIEW which then gets displayed to the users.

The MCV architecture can be used with many different programming languages like ASP.net , JavaScript and PHP. But here specifically, we will discuss things based on PHP and to be more precise, Laravel, A PHP framework.
If you want to learn about some other programming language, don't worry, the concept of MVC remains the same no matter what language it is.

WHAT ARE CONTROLLERS ?

As discussed above, a CONTROLLER is what interacts with the MODEL to fetch the data and display it to the user. 
It acts as a co-ordinator between the VIEW and the MODEL. Controller have a two way communication, that means, it recieves the data from VIEW (What a user wants to be displayed), then communicates with the MODEL to fetch that particular data and then after the data is fetched, communicates back to a VIEW to send all the data recieved.


WHAT ARE MODELS ?

Models are responsible for managing the data of an application.It can manage offline data or the data stored inside of a database. All the data requests are sent to the MODEL for it to process before it sends back the processed data to the CONTROLLER. 

WHAT ARE VIEWS ?

VIEWS serve the user. Suppose you visit a site, say, example.com/users, as soon as you hit RETURN, the request gets sent to the controller that then communicates with model to gather all required information for that particular route and sends it back to the route namely /users and then everything gets rendered and you see the users page of the website.


We will discuss how we can use MODELS, VIEWS and CONTROLLERS in Laravel in a later post.

WHAT IS LARAVEL ? Laravel is a PHP framework. It is an MVC framework that is designed to ease your backend efforts and to minimize the keystrokes and maximize the output. With Laravel, you don't have to write several lines of codes just to achieve a simple task as you do in Vanilla PHP. For example, in PHP if one wants to fetch all the results from the database, they have to write code similar to one below  notice the number of keystrokes and a mess it would be to query multiple databases in multiple lines. Thankfully, Laravel got us covered. In Laravel the same thing can be done in a much simpler way as below  With just that, we fetch all the content of our "Table". The table keywork in the above snippet is the Model reference.  You can read more about Models here GETTING STARTED WITH LARAVEL Setting up Laravel is pretty simple, but for that, you need to have Composer installed on your computer.  After installing composer, you need to make sure that you have a local ser

WHAT IS VUE.JS ? Have you ever came across the techonology named Vue and wondered what exactly it is?   Vue js is an open source JavaScript framework for building the front end of your website. With the help of Vue, you can create modern looking Single Page Applications (SPA). A SPA have less loading time as compared to a normal website because the pages and components gets loaded all together at the start and that means, a user can navigate through the whole website without reloading the page and that saves quiet a lot of time and enhances the user experience aswell.  Vue.js was developed by Evan You and it is written in JavaScript. It have a Model-View View-Model architecture. The MVVM architecture seperates the User interface with the back end functionalities of the website.  The routing in Vue applications are done using the Vue Router libraries which we will discuss in later articles.  Vue.js have a state management system which can be used for passing data along the components fr
