LxD Series: Laravel Basics

Before we dive into coding Laravel based app, let’s learn what’s it all about.

Laravel is an MVC based framework for rapid PHP based web application development. MVC(Model-View-Controller) is a design pattern used to write softwares. It consist of three parts:

  • Model: This component deals with data and it’s manipulation. Usually you deal with database(RDBMS,NoSQL) here but this is not necessary at all. Your model could interact with a flat file or some remote API for data manipulation.
  • View: The data which was processed or manipulated on model layer is shown by Views to end-users so that they could interact with the app.
  • Controller: Controller actually sits between View and Model and works as a bridge between two. Controller could be used to processed the data you fetch from Model and make it presentable to view as per your need.


In simplest word Routing is a mechanism used to map one kind of URL to another. Routing is used to convert ugly looking URLs to user-friendly or SEO friendly URL. So if there’s a URL http://example.com/users/user?id=12&name=Jhon, routing can convert it to http://exampe.com/users/user/12/Jhon. Prior to MVC frameworks we used to write multiple rules to cater different kind of URLS. MVC frameworks like Larave provides an easy way to come up a URL format as per your need. Behind the scene it still uses .htacess file. Laravel takes the benefit of Closure to implement routing.


Usually when you create a database driven app you will create a sql script to create tables in db. Later when you go in production you have to run script on remote server. While working in a team and multiple developers making changes in a single database. It gets difficult to keep a track of it. Migrations help you to overcome this issue. You create migration files which contains timestamp in file name which contains an expressive syntax to create/drop tables. You can run a certain migration command on your local machine or remote server that will execute script in order.

Laravel provides easy to use command to perform various migration related operations. For instance:

php artisan migrate:make create_users_table

Will create a migration file that will be responsible to create a table users. It will create a file like this:

public function up()
    Schema::create('users', function($table)

public function down()

create creates a table users while down drops it.

That’s all folks. In coming post we will be implementing routes and design in our Laravel app. Stay tuned!
