Laravel - Application Structure

Laravel follows a well-organized and convention-based application structure that promotes code organization, separation of concerns, and ease of maintenance. Understanding the Laravel application structure is essential for developers working on Laravel projects. Here's an overview of the main directories and files in a typical Laravel application:

1. app Directory:

• Console: Contains Artisan commands.
• Exceptions: Custom exception handler and exception rendering.
• Http: Controllers, middleware, and form requests.
• Providers: Service providers that register services with the application.

2. bootstrap Directory:

• app.php: Initializes the Laravel application.

3. config Directory:

• Contains configuration files for various services and components.

4. database Directory:

• migrations: Database migration files.
• seeders: Database seeder files.

5. public Directory:

• The entry point for the web server. Contains the index.php file and public assets (CSS, JavaScript, images).

6. resources Directory:

• css, js, lang: Front-end assets and language files.
• views: Blade templates for the views.

• The resources directory is where you organize your views and front-end assets.
• The storage directory is used to store generated files, such as logs and cached files.
