Laravel Routing Overview

Study Notes

Overview of Laravel Routing

Laravel routing enables URL handling and directs requests to the appropriate controller methods.
Routes are defined in the routes/web.php file for web applications.

Basic Routing

Simple route definition:

Route::get('/home', function() {
    return view('home');
});

This defines a route that returns the 'home' view when a GET request is made to /home.

Route Parameters

Required Parameters: Enclose in {} brackets.

Route::get('/user/{id}', function($id) {
    return 'User '.$id;
});

Optional Parameters: Follow with a ?.

Route::get('/user/{name?}', function($name = 'Guest') {
    return 'User '.$name;
});

Route Constraints

Specify constraints for route parameters using regular expressions.

Route::get('/user/{id}', function($id) {
    // Your code here
})->where('id', '[0-9]+');

Route Methods

Support for various HTTP methods:
- Route::get()
- Route::post()
- Route::put()
- Route::delete()
- Route::patch()

Named Routes

Assign a name to a route to simplify URL generation and redirection.

Route::get('/profile', [UserController::class, 'show'])->name('profile');

Generate URLs using the route name:
```
route('profile');
```

Route Grouping

Organize routes that share attributes, like middleware or prefixes.

Route::middleware(['auth'])->group(function () {
    Route::get('/dashboard', 'DashboardController@index');
    Route::get('/settings', 'SettingsController@index');
});

Resourceful Routing

Quickly define routes for a resource.

Route::resource('photos', PhotoController::class);

Generates routes for typical actions: index, create, store, show, edit, update, and destroy.

Route Caching

Optimize route registration for production using php artisan route:cache.

Route Redirects

Redirect from one URL to another.

Route::redirect('/here', '/there', 301);

Route Middleware

Attach middleware for route filtering (e.g., authentication).

Route::get('/admin', 'AdminController@index')->middleware('admin');

Conclusion

Laravel routing is a powerful feature that facilitates clean, readable URL management.
Understanding its capabilities enhances the organization of web application routes.
