Today, we will cover Laravel, its installation, file structure, artisan, routing, middleware, blade, Eloquent ORM, CRUD, and best coding practices.
Laravel is an MVC PHP framework developed in 2011, known for its powerful features like Eloquent ORM, migrations, and Blade template engine.
Laravel dependencies are managed via Composer, using a project-based tool for installing Laravel.
Laravel's file structure includes essential directories: Controllers, Models, configuration files, migrations, public assets, and routes.
Artisan is a command-line tool for Laravel that aids in generating files and optimizing workflow.
Laravel offers a robust routing system with middleware support and request methods. Importance of naming routes and order.
Middleware filters HTTP requests. Key middleware include Authentication and CSRF protection mechanisms.
Blade is Laravel's template engine, converting code into static HTML, supporting PHP code, and enhancing layout management.
Eloquent ORM allows simple database operations via model classes, providing an integrated Active Record approach.
Engagement in a practical task related to CRUD operations in Laravel.
Best practices include using models appropriately, ensuring CSRF protection, database design considerations, efficient queries, and maintaining code comments.

- 7. app/Http folder containsthe Controllers, Middlewares and Kernel file All the models should be located in app/Models folder All the config files are located in app/config folder The service providers that are bootstrapping functions in our app are located in app/Providers folder Folder Structure
- 8. Folder Structure • Databasefolder contains the migrations and seeds • The public folder is the actual folder you are opening on the web server. All JS / CSS / Images / Uploads are located there. • The resources folder contains all the translations, views and assets (SASS, LESS, JS) that are compiled into public folder • The routes folder contains all the routes for the project • All the logs / cache files are located in storage folder • The vendor folder contains all the composer packages (dependencies)
- 9. Artisan is command-lineinterface for Laravel Commands that are saving time Generating files with artisan is recommended Run php artisan list in the console Artisan!
- 10. • The bestand easy routing system I’ve seen • Routing per middleware / prefix or namespace • Routing per request method (GET, POST, DELETE, etc.) • ALWAYS name your route ! • Be careful with the routing order ! Let’s see routing examples Routing
- 11. • The middlewareis mechanism for filtering the HTTP requests • Laravel includes several middleware's – Authentication, CSRF Protection • The auth middleware checks if the user visiting the page is authenticated through session cookie • The CSRF token protection middleware protects your application from cross-site request forgery attacks by adding token key for each generated form Let’s create middleware Middleware
- 12. • Blade isthe powerful template engine provided by Laravel • All the code inside blade file is compiled to static html file • Supports plain PHP • Saves time • Better components mobility, extend and include partials Let’s take a look at few examples Blade

- 16. Best practices in •NEVER write queries or model logic inside the controller! The controller job is to communicate with the model and pass data to the view.
- 17. Extend and includepartials. For example share the same form fields on 2 pages – add and edit Views mobility
- 18. Always use theCSRF token protection that Laravel provides in forms you create, the hackers will not be able to spam your forms and database Forms security
- 19. Be careful withthe database architecture, always use the proper length for specific column and never forget the indexes for searchable columns Database architecture
- 20. • Avoid thebig query unless you really have to do it. The big query is hard to debug and understand. • You can merge the small queries into one to save the CPU time on server, but sometimes the query becomes way too big. Big Query
- 21. Don’t forget towrite comments for each method or complicated logic. The PHPDoc comments are helping the IDE to autosuggest easier and the developers to understand the piece of code Don’t forget the PHPDoc
