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.phpfile 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.
Laravel Routing
- Defines how a web application responds to different URLs
- Routes are stored in the
routes/web.phpfile - Used to direct requests to the appropriate controller methods
Basic Routes
- Use the
Route::get()method to define a route for a GET request - Defines a route that returns a specific view when a GET request is made to a given URL
Route Parameters
- Enables dynamic URL patterns
-
{}brackets for required URL parameters -
?for optional parameters - Optional parameters have a default value assigned
Route Constraints
- Limit route parameters to specific values using regular expressions
- Enforce data types or specific formats for URLs
Route Methods
- Support for various HTTP verbs:
-
Route::get()- for GET requests. -
Route::post()- for POST requests. -
Route::put()- for PUT requests. -
Route::delete()- for DELETE requests. -
Route::patch()- for PATCH requests.
-
Named Routes
- Assign a name to a route
- Simplifies URL generation
- Easier to reference routes and generate URLs within the application
- Generate URLs using the route name
Route Grouping
- Organizing routes that share attributes, like middleware or prefixes.
- Apply middleware or prefixes to multiple routes without repeating code
Resourceful Routing
- Automatically generates CRUD operations for a resource
- Provides routes for standard actions such as:
-
index- List all resources. -
create- Display a form to create a new resource. -
store- Store a newly created resource. -
show- Display details of a specific resource. -
edit- Display a form to edit an existing resource. -
update- Update an existing resource. -
destroy- Delete a resource.
-
Route Caching
- Optimize route registration
- Improves performance by storing routes in a cache file
Route Redirects
- Redirects users from one URL to another.
- Specify a status code (e.g., 301 for permanent redirection).
Route Middleware
- Apply middleware to routes to perform actions before the request is handled by the route.
- Examples include:
- authentication
- authorization
- logging
- rate limiting.
