How to follow best practices for Laravel development
Following Laravel best practices ensures that the code is neat, maintainable and scalable, and the answer is to use the correct MVC structure, leverage built-in features, comply with PSR standards, manage configuration rationally, strengthen security, write tests, organize large applications, optimize performance, use version control, and continuous updates. 1.

The scope should only build queries and do not include business logic; 5. It must be called through model classes, and cannot be called through model instances, thereby improving code reusability, readability and maintenance.

How to use the pipeline design pattern in Laravel?
Laravel's pipeline design pattern is suitable for scenarios where data needs to be processed multiple steps. 1. Define the processing stage (such as TrimStrings, ConvertToUppercase, EnsureEndingPeriod and other classes that implement handle methods, 2. Use Pipeline::send() in a service or controller to pass the data through the class list specified by () and receive the final result by then(). 3. Optionally use closures to replace the class to simplify simple logic. 4. In Laravel9, objects can be passed as context for each pipeline to share. This pattern is suitable for form preprocessing, queue tasks, workflow construction and other scenarios. The pipeline should be maintained.
