Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.

Create a seeder file: Use phpartisanmake:seederUserSeeder to generate the seeder class, and insert data through the model factory or database query in the run method; 2. Call other seeder in DatabaseSeeder: register UserSeeder, PostSeeder, etc. in order through $this->call() to ensure the dependency is correct; 3. Run seeder: execute phpartisandb:seed to run all registered seeders, or use phpartisanmigrate:fresh--seed to reset and refill the data; 4

Use the composerremove command to uninstall packages in PHP projects. This command removes the specified package from the composer.json's require or require-dev and automatically adjusts the dependencies. 1. Execute composerremovevevendor/package to remove from require; 2. Use the --dev parameter to remove from require-dev; 3. Composer will automatically update the dependencies and rebuild the automatic loader; 4. You can run composerinstall and check the vendor/directory to ensure thorough cleaning; 5. Finally submit version control changes to save the modification.

The use of warehousing mode is to separate data access logic from business logic. 1. Define the warehousing interface and clarify the data operation method; 2. Create specific implementation classes based on Eloquent encapsulate database queries; 3. Use warehousing interfaces through dependency injection in the controller; 4. Bind interfaces and implementation classes in the service provider; ultimately implement code decoupling, improve testability and maintainability, and is suitable for scenarios where medium and large applications or require flexibly switching data sources.

Create a new Laravel project and start the service; 2. Generate the model, migration and controller and run the migration; 3. Define the RESTful route in routes/api.php; 4. Implement the addition, deletion, modification and query method in PostController and return the JSON response; 5. Use Postman or curl to test the API function; 6. Optionally add API authentication through Sanctum; finally obtain a clear structure, complete and extensible LaravelRESTAPI, suitable for practical applications.
