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

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.
