Creating a route in Laravel PHP Framework

Creating a route in Laravel PHP Framework

In the dynamic world of web development, Laravel stands out as a robust PHP framework designed to facilitate the rapid creation of high-quality web applications. One of the key features that contribute to its efficiency and popularity among developers is its routing capability. Routing in Laravel is not just about navigating between pages; it’s about crafting a seamless and intuitive user experience, making it an indispensable aspect of modern web development.


Laravel has cemented its position in the PHP community as a preferred framework due to its elegant syntax, comprehensive feature set, and emphasis on modern practices. One of the cornerstones of Laravel’s design is its routing engine, which allows developers to define the way their web applications respond to user requests. In essence, routing is the mechanism that maps web requests to specific controller actions or closures, thereby enabling the creation of responsive web applications.

Understanding Routing in Laravel

Routes in Laravel are the rules that specify how an application responds to a client request to a specific path or endpoint. The routes folder, found at the root of every Laravel project, is the heart of routing in Laravel. This folder contains files that define all the routes for your application. Understanding the purpose and functionality of each file within this folder is crucial for effective Laravel development.

The Role of the routes Folder

The routes folder houses four primary files: web.php, api.php, console.php, and channels.php. Each file serves a distinct purpose:

  • web.php is used for routing web requests that involve a user interface, like returning views or handling form submissions.
  • api.php caters to stateless API routes, which are typically used in AJAX requests and mobile application interfaces.
  • console.php defines console-based entry points for scheduled tasks and artisan commands.
  • channels.php is for registering all of the event broadcasting channels that your application supports.

Basic Routing

Defining basic GET routes in web.php is straightforward. A simple route can return a string directly or delegate the request to a view or controller. Here’s how to define a basic GET route that returns a string:

Route::get('/greeting', function () {
return 'Hello, World!';

To return a view, you can use:

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

Beyond GET requests, Laravel supports other HTTP verbs including POST, PUT, DELETE, PATCH, and OPTIONS.

HTTP Verbs

Laravel makes it simple to define routes for different HTTP verbs:

1Route::post('/profile', function () {
2 // Handle the request...
5Route::put('/profile', function () {
6 // Handle the request...
9Route::delete('/profile', function () {
10 // Handle the request...

Route Parameters

Laravel routes can also include required or optional parameters, enabling dynamic response generation based on the input provided in the URL.

Required Parameters

To define a route with a required parameter:

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

Optional Parameters

Optional parameters are defined by adding a ? to the parameter name and providing a default value:

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

Named Routes

Named routes allow you to reference routes in a more flexible way, making it easier to generate URLs or redirects. To define a named route, you can chain the name method onto the route definition:

Route::get('/user/profile', function () {
// Your code here...

Using named routes simplifies the process of changing URLs as your application evolves, without needing to update references in multiple places.

Route Groups

In Laravel, Route Groups allow you to share route attributes, such as middleware or prefixes, across a large number of routes without needing to define those attributes on each individual route. This is particularly useful for organizing a series of routes under a common namespace or prefix. For instance, you might want to prefix all routes related to the admin panel with ‘admin’:

Route::prefix('admin')->group(function () {
Route::get('/', 'AdminController@index');
Route::get('profile', 'AdminController@profile');

Additionally, Route Groups can be used to assign middleware to a group of routes, ensuring that only authenticated users can access certain routes, for example.


Middleware in Laravel acts as a filtering mechanism that runs before or after a request is processed by the application. You can assign middleware to routes to perform tasks like authentication checks or logging. To assign middleware to a route, you can use the middleware method:

Route::get('profile', 'UserController@profile')->middleware('auth');

This ensures that only authenticated users can access the profile route.

Resource Controllers

Resource Controllers in Laravel simplify the management of CRUD (Create, Read, Update, Delete) operations on resources. By using a single controller, you can handle all the necessary actions for a resource. To create a resource route, you can use the Route::resource method:

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

This single line creates multiple routes to handle a variety of RESTful actions on the photos resource.

Advanced Routing Concepts

Domain Routing

Laravel allows you to route requests for different domains using the domain method. This is useful for applications serving multiple domains from the same codebase:

Route::domain('{user}.myapp.com')->group(function () {
Route::get('user/{id}', function ($user, $id) {

Rate Limiting

Implementing rate limits on routes can protect your application from abuse and overuse. Laravel makes it easy to define rate limits:

Route::middleware('auth:api', 'throttle:60,1')->group(function () {
Route::get('/user', function () {

Form Method Spoofing

Laravel allows you to “spoof” form methods, enabling you to support RESTful actions using HTML forms:

<form action="/foo/bar" method="POST">
<input type="hidden" name="_method" value="PUT">
{{ csrf_field() }}

Redirect Routes

Creating redirect routes is straightforward in Laravel, allowing you to redirect one route to another:

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

Best Practices

Organizing routes in a large application is crucial for maintainability. Keep your route files clean and focused, separating routes into different files based on their functionality. Utilizing route caching (php artisan route:cache) can significantly improve performance by reducing route registration time.

Common issues like “route not found” errors or middleware-related issues can often be resolved by ensuring that routes are correctly defined and middleware is properly assigned. Use php artisan route:list to debug and list all registered routes.
