Everything you Need to Know About Laravel Lumen Microservice

Key Features of Lumen

1. Routing

The routing facility, in the case of Lumen, is provided through Fast Rout. Fast Rout is a library for enabling a quick implementation of a regular expression based router. A developer should define all routes of the app in the routes/web.php file. Lumen routes simply accept a URI & a closure.

This is the list of router methods used for Lumen framework:

$app->get($uri, $callback);

$app->post($uri, $callback);

$app->put($uri, $callback);

$app->patch($uri, $callback);

$app->delete($uri, $callback);

$app->options($uri, $callback);

2. Authentication

Since Lumen does not support the concept of sessions, all requests authenticate through stateless mechanisms, like API tokes.

The AuthServiceProvider is located in the app/providers. It involves a single call to Auth::viaRequest. The method accepts a closure. When an authentication request arrives, the closure comes into play. In case no authentication is found for the request, the method returns a null.

The Auth:user() method helps obtain the authenticated user. One may alternately use $request->user() method on an IlluminateHttpRequest instance for the same.

3. Authorization

Lumen has a straightforward way to organize authorization logic and makes a simplified way available to access these resources. In Lumen, authorization is similar to how it is in the Laravel micro framework, barring a few adjustments.

The ways to define abilities are different in Laravel and Lumen. One can use the Gate facade in AuthServiceProvider to define abilities in Lumen:

Gate::define('update-post', function ($user, $post) {

return $user->id === $post->user_id;

});

Similarly in Lumen, one cannot define $policies array on the AuthServiceProvider. But one can call the policy on Gate facade

Gate::policy(Post::class, PostPolicy::class);

4. Caching

In Lumen caching, mechanisms have similarities with the Laravel framework. The code used by Lumen cache driver is the same as the code used by Laravel. Lumen also supports popular caching backends such as Redis and Memcached.

5. Encryption

Before one uses Lumen’s encrypter, one should go to the application key option of the .env file, and set it to a random, 32 character string. Authorization and authentication are some of the ways to uplift business using Laravel app development.

Values are encrypted in Lumen using the Crypt façade. All values are encrypted using the AES-256-CBC cipher and OpenSSL. The values are signed with a MAC (Message Authentication Code) for detecting any modification.

6. Errors & Logging

Error & exception handling mechanism is inherited in your project by default upon starting a new project in the Lumen framework. Additionally, Lumen is also integrated with Monolog. Monolog is a logging library that supports a range of log handlers. Managing errors explicitly is hence not needed.

7. Events

Lumen’s events make a simple observer implementation possible. Using the same, one can subscribe and listen to the events in his app. The listeners are stored in app/Listeners directory and events classes are stored in the app/event.

Similar to the Laravel framework, the EventServiceProvider is included in the Lumen app as well. It offers a way of registering event listeners.

Conclusion

Across the years gone by, agile web applications have been in high demand. Lumen makes a preferred option to go ahead with in such circumstances, in particular for lightweight and small apps. With our expertise over Lumen, Cyblance is the preferred laravel development agency for your requirements.
