Introduction to Laravel

Post Views: 29

Laravel is an open source PHP framework. Framework is a tool which is used to make modern, fast and scalable products. Laravel is based on model–view–controller (MVC) architectural pattern. Some of the features of Laravel are a modular packaging system with a dedicated dependency manager, different ways for accessing relational databases, utilities that aid in application deployment and maintenance, and its orientation toward syntactic sugar.

MVC

The Model-View-Controller (MVC) is an pattern which separates an application into three main logical components: the model, the view, and the controller. Each of these components are built to handle specific development aspects of an application. MVC is one of the most frequently used industry-standard web development framework to create scalable and extensible projects.

MVC Structure

Basic MVC Architecture. Model View Controller or MVC as it is popularly called, is a software design pattern for developing web applications.

A Model View Controller pattern is made up of the following three parts −

Model − The lowest level of the pattern which is responsible for maintaining data.
View − This is responsible for displaying all or a portion of the data to the user.
Controller − Software Code that controls the interactions between the Model and View.

MVC isolates the application logic from the user interface layer and supports separation of concerns.

Here the Controller receives all requests for the application and then works with the Model to prepare any data needed by the View.

The View then uses the data prepared by the Controller to generate a final presentable response.

The MVC abstraction can be graphically represented as follows:-

Setting up Laravel

For setting up a laravel we need to install composer in our device and then we have to open a terminal and run the following command:

composer global require laravel/installer

Once it’s done, you can create a fresh Laravel project with the laravel new command in the directory you’re in.

In your terminal go to the root of your webserver and run

laravel new your_project_name

Artisan Command

Artisan is the command line interface included with Laravel. Artisan exists at the root of your application as the artisan script and provides a number of helpful commands that can assist you while you build your application. To view a list of all available Artisan commands, you may use the list command:

php artisan list
