Here we are going to talk a bit about the built of the Laravel application and how files and folders are sorted.

/app_root/.env	Very important file, contains all the environment variables and sensitive data necessary to run the app such as MySQL database credentials, Mail server details and AWS details. (should git-ignored) if we plan to share the code online.
/app_root/app/	all Models in the app live directly under this directory
/app_root/app/Http/Controllers/	all Controllers of the app live under this directory
/app_root/app/Http/Middleware	this is the home of the URLS traffic guard, to filter out unauthorised requests and throw 403 error
/app_root/config/database.php	for DB connection details
/app_root/config/filesystems.php	identify services like S3 cloud configuration
/approotdirectory/Database/factories/	to create mock data for testing
/approotdirectory/Database/migrations/	to create tables and columns
/approotdirectory/public/	home of the app for public access
/approotdirectory/public/.htaccess	redirect all traffic to index.php
/approotdirectory/public/index.php	processing of all traffic starts here
/approotdirectory/public/robots.txt	instructions for search engine spiders
/approotdirectory/public/css/app.css	compiled .css styling files
/approotdirectory/resources/views	all blades (Views) live under this directory
/approotdirectory/routes/web.php	for ROUTING traffic from the internet space to controllers in the file system
/approotdirectory/storage	the default uploaded files home (within sub-folders)
/approotdirectory/storage/logs/laravel.log	Laravel log file to hold errors or whatever we want (ie emails for testing)
