What are the benefits of using routing in laravel?

Laravel is a very popular PHP framework. A very important part of its main MVC architecture is the routing system. Laravel's routing system has unique designs and advantages compared to other PHP frameworks. The following will introduce the benefits of using routing in Laravel.

What is Laravel routing

Laravel routing is the URL conversion mechanism for web applications. It allows us to map URLs to specific actions passed to the application. Using Laravel routing, we can distribute requests to the corresponding controller methods, while also specifying HTTP verbs, URL parameters, and other conditions.

Why use Laravel routing

Laravel routing is an important part of web applications. The following are several advantages of Laravel routing:

1. Enhance maintainability

Using Laravel routing, we can route requests to a specific set of controller methods, which helps the application stay clean and organized. We can classify routes according to function or type grouping to better organize and maintain the entire application.

2. Increase application scalability

In Laravel, routing and controller methods are loosely coupled. This means we can add, remove and change controller methods and routes without affecting other parts. Therefore Laravel routing can provide a good foundation for application scalability.

3. Improve application readability

Laravel routing can make the URL pattern of the entire web application clearer and easier to read. We can name routes in routes, use namespaces, etc. to improve readability.

4. Provide better security

Laravel routing can provide better security, which is a common problem in traditional GET requests. Laravel uses the POST method by default to handle form submissions, which is very safe. Routes can also enhance security with optional security tokens and middleware.

5. Provide convenience during testing

The Laravel routing system makes routing testing very easy. We can easily set up request parameters and routes and then test different features and scenarios of our application.

Types of Laravel routing

Laravel routing can be divided into three different types: basic routing, controller routing and RESTful routing.

1. Basic routing

Basic routing is the most common type of routing. When defining a basic route, we need to specify the requested URI and the action to perform. For example:

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

The above code indicates that when requesting /hello URI through GET, calling an anonymous function without parameters returns the words "Hello World!".

2. Controller routing

Controller routing routes requests to methods in the controller class. Doing so separates routing from the application's business logic and controller method structure. For example:

Route::get('/users', 'UserController@index');

The above code indicates that when a GET request is made for the /users URI, the request is processed by calling the index method of the UserController class.

3. RESTful routing

RESTful routing is a route specially designed for RESTful API. RESTful routing allows for fluent requesting of resources, allocating resources to specified HTTP verbs and request types. For example:

Route::apiResource('users', 'UserController');

The above code creates RESTful API users, and then handles related requests through the UserController class.

Conclusion

Overall, Laravel routing provides a flexible, smart, and powerful way to route requests to applications. Several of its advantages include enhanced maintainability, better scalability, better security, better readability, and easier testing. Additionally, the flexibility between the three existing Laravel routing types means we can choose the appropriate routing type to meet the required functionality and requests.
