The default Laravel application structure is intended to provide a great starting point for both large and small applications. Of course, you are free to organize your application however you like. Laravel imposes almost no restrictions on where any given class is located - as long as Composer can autoload the class.
The root directory of a fresh Laravel installation contains a variety of folders:
app directory, as you might expect, contains the core code of your application. We'll explore this folder in more detail soon.
bootstrap folder contains a few files that bootstrap the framework and configure autoloading, as well as a
cache folder that contains a few framework generated files for bootstrap performance optimization.
config directory, as the name implies, contains all of your application's configuration files.
database folder contains your database migration and seeds. If you wish, you may also use this folder to hold an SQLite database.
resources directory contains your views, raw assets (LESS, SASS, CoffeeScript), and localization files.
storage directory contains compiled Blade templates, file based sessions, file caches, and other files generated by the framework. This folder is segregated into
logs directories. The
app directory may be used to store any files utilized by your application. The
framework directory is used to store framework generated files and caches. Finally, the
logs directory contains your application's log files.
tests directory contains your automated tests. An example PHPUnit is provided out of the box.
vendor directory contains your Composer dependencies.
The "meat" of your application lives in the
app directory. By default, this directory is namespaced under
App and is autoloaded by Composer using the PSR-4 autoloading standard.
app directory ships with a variety of additional directories such as
Providers. Think of the
Http directories as providing an API into the "core" of your application. The HTTP protocol and CLI are both mechanisms to interact with your application, but do not actually contain application logic. In other words, they are simply two ways of issuing commands to your application. The
Console directory contains all of your Artisan commands, while the
Http directory contains your controllers, middleware, and requests.
Events directory, as you might expect, houses event classes. Events may be used to alert other parts of your application that a given action has occurred, providing a great deal of flexibility and decoupling.
Exceptions directory contains your application's exception handler and is also a good place to stick any exceptions thrown by your application.
Jobs directory, of course, houses the queueable jobs for your application. Jobs may be queued by your application or run synchronously within the current request lifecycle.
Listeners directory contains the handler classes for your events. Handlers receive an event and perform logic in response to the event being fired. For example, a
UserRegistered event might be handled by a
Policies directory contains the authorization policy classes for your application. Policies are used to determine if a user can perform a given action against a resource. For more information, check out the authorization documentation.
Note: Many of the classes in the
appdirectory can be generated by Artisan via commands. To review the available commands, run the
php artisan list makecommand in your terminal.
