Getting Started With Laravel Framework

Prerequisites

Installing Laravel Framework

We need to download and install Laravel through Composer command in Terminal / Console, to do that type-in the following command.

λ composer global require "laravel/installer=~1.1"

Once installed, laravel new command will create a fresh Laravel Installation in the current directory. Let's create one new project by utilizing laravel CLI.

λ laravel new my-app

Next, change your current directory to the root folder of the project.

λ cd my-app

To start the Laravel Server, type the following command in your Terminal / Console.

λ php artisan serve

You will be able to visit your application on http://127.0.0.1:8000

Model-View-Controller (M.V.C) Architecture

M.V.C – is an architectural design in pattern that separates a Laravel application into three main logical components –

  • Model
  • View
  • Controller

Model > Model components have all the data related logic and business logic of the application.

View > View holds all the User Interface logic of the application. We can retrieve and show the data to the user using View.

Controller > Controller acts as an interface between Model and View Components to process all the business logic and incoming requests.

This post explains only the essential component of Laravel Framework. Laravel can be useful to create advance web application with complex logic and industry grade security.

It provides Out of the Box (OOB) encryption, and data encapsulation, which makes laravel a robust framework. Visit Laravel Framework Documentation for more clear understanding.
