Explanation Of The Concepts Of Laravel, What Are The Advantages Of Using Laravel Framework, How To Install Composer, Command "php artisan serve" And The Application Structure Of myApp Inside Laravel Folder

NOTE: I can check that whether composer is successfully installed in my system or not in two ways in composer command prompt. One is composer --version and another way is composer.

So, firstly just let me explain about Laravel. So, What is Laravel? Laravel is a framework which consists of MVC Framework i.e. Model, View And Controller. Laravel consists of bundles, migrations and artisan CLIs(Command Line Interfaces). It is an open source framework.

Now coming to my next topic that is what are the advantages of using Laravel Framework? So, the advantages of using Laravel Framework is it consists of rich set of features which will boost the speed of Web Development. Another advantages is that whathever websites are built using Laravel Framwork are much more secure than any other framework like CodeIgnitor.

Now coming to how to install composer? So, to install composer first I need to go to chrome or google and type https://getcomposer.org/download/ and then we need to download Composer-Setup.exe as shown in my image below which I have uploaded and once composer is downloaded I need to install the composer file by clicking on Next -> Next button. As in my system already composer is installed so I am not installing again.

How to verify that composer installed or not properly? So, to verify that composer is installed or not properly I need to type a command " composer --version" in cmd (command prompt) or I can also verify that whether composer is installed or not in another way that is only by typing "composer" command in cmd (command prompt).

Now coming to how to create Laravel Project using composer command. So, the command is "composer create-project Laravel/Laravel myApp "10.x".

Now just let me explain what does the command "php artisan serve" means. So, basically the command "php artisan serve" means it creates a live development server running on default port 8000.

Now, finally just let me explain about the Application Structure of myApp inside Laravel Folder. So, inside Application Structure of myApp inside Laravel Folder we have many folders like app, bootstrap, config, database, myApp, public, resources,routes, storage, tests, vendor, and files like  .editconfig, .env,.env.example,.gitatrributes, .gitignore, artisan, composer, composer.lock, package, phpunit, README, vite.config. 

So, before starting with the explanation of the first folder i.e. App folder. Just let me tell you that what is basically myApp. So, myApp is basically the root directory as shown in my image below.

Now starting with the explanation of the first folder App.

App Folder - This directory basically consists the code of the application.

Bootstrap Folder - This directory basically consists the scripts of the bootstrap application.

Config Folder - This directory contains the directory files of the applications.

Database Folder - This directory consists its own database migration and sheets. It has all the information related to the database associated with application.

Routes Folder - This directory consists of api files, channels files, console files and web files.

Storage Folder - This directory consists of app storage like file folders, framwork storage and application related logs.
