Regarding Laravel's route cache, some developers may not be very clear about its role and specific implementation. So, this article will introduce you to the relevant content of Laravel routing cache in detail.

The role of Laravel route cache

In Laravel, routing is one of the core components of the application. Through route caching, the route resolution time can be greatly reduced, allowing applications to respond to requests faster.

Specifically, when we execute the "php artisan route:cache" command, Laravel will cache all routing information in a file. The default address of this file is "bootstrap/cache/routes.php" . In this way, on the next request, Laravel can directly read the routing information in the file without having to re-parse the route, thus improving the performance of the application.

It should be noted that route caching is only enabled in the production environment, because in the development environment, frequent modifications to the routing files will cause cache invalidation and cause problems.

How to implement Laravel route cache

So, how do we use Laravel route cache function? The specific steps are as follows:

1. First, make sure your application is in a production environment. If you are not sure, you can check the "APP_ENV" option in the configuration file "config/app.php".

2. Execute the "php artisan route:cache" command in the terminal, and Laravel will cache all routing information in the "bootstrap/cache/routes.php" file.

3. Add a new route in Laravel's routing file (default is "routes/web.php" and "routes/api.php"), and then execute the "php artisan route:cache" command to Corresponding routing information will be added in the "routes.php" file.

4. If you need to refresh the route cache, you can execute the "php artisan route:clear" command, which will delete the cache information in the "bootstrap/cache/routes.php" file.

It should be noted that if Closures (anonymous functions) are used in your application, the route caching function cannot be used. Because Closures are a non-serializable object in PHP and cannot be written to a file.

In addition, when using the route cache function, you need to pay special attention to the following aspects:

1. The route cache only caches GET and HEAD routes in the file, POST, PUT, Routes such as DELETE and PATCH still need to be parsed and processed.

2. The route cache will ignore all middleware, which means that if your application uses middleware for route protection or other processing, it still needs to perform a complete route resolution process.

3. After using the route cache function, you need to refresh the cache regularly, otherwise unnecessary problems may occur.

Summary

In this article, we have a detailed introduction to Laravel's route cache. By using route caching, we can improve application performance and shorten request response time to a certain extent. However, it should be noted that route caching is not omnipotent. We need to judge whether to use this function based on specific needs.
