How to completely remove Laravel without affecting other projects

Laravel performance optimization can improve application efficiency through four core directions. 1. Use the cache mechanism to reduce duplicate queries, store infrequently changing data through Cache::remember() and other methods to reduce database access frequency; 2. Optimize database from the model to query statements, avoid N 1 queries, specifying field queries, adding indexes, paging processing and reading and writing separation, and reduce bottlenecks; 3. Use time-consuming operations such as email sending and file exporting to queue asynchronous processing, use Supervisor to manage workers and set up retry mechanisms; 4. Use middleware and service providers reasonably to avoid complex logic and unnecessary initialization code, and delay loading of services to improve startup efficiency.

LaravelSanctum is suitable for simple, lightweight API certifications such as SPA or mobile applications, while Passport is suitable for scenarios where full OAuth2 functionality is required. 1. Sanctum provides token-based authentication, suitable for first-party clients; 2. Passport supports complex processes such as authorization codes and client credentials, suitable for third-party developers to access; 3. Sanctum installation and configuration are simpler and maintenance costs are low; 4. Passport functions are comprehensive but configuration is complex, suitable for platforms that require fine permission control. When selecting, you should determine whether the OAuth2 feature is required based on the project requirements.

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.

Laravel simplifies database transaction processing with built-in support. 1. Use the DB::transaction() method to automatically commit or rollback operations to ensure data integrity; 2. Support nested transactions and implement them through savepoints, but it is usually recommended to use a single transaction wrapper to avoid complexity; 3. Provide manual control methods such as beginTransaction(), commit() and rollBack(), suitable for scenarios that require more flexible processing; 4. Best practices include keeping transactions short, only using them when necessary, testing failures, and recording rollback information. Rationally choosing transaction management methods can help improve application reliability and performance.

The core of handling HTTP requests and responses in Laravel is to master the acquisition of request data, response return and file upload. 1. When receiving request data, you can inject the Request instance through type prompts and use input() or magic methods to obtain fields, and combine validate() or form request classes for verification; 2. Return response supports strings, views, JSON, responses with status codes and headers and redirect operations; 3. When processing file uploads, you need to use the file() method and store() to store files. Before uploading, you should verify the file type and size, and the storage path can be saved to the database.

The most common way to generate a named route in Laravel is to use the route() helper function, which automatically matches the path based on the route name and handles parameter binding. 1. Pass the route name and parameters in the controller or view, such as route('user.profile',['id'=>1]); 2. When multiple parameters, you only need to pass the array, and the order does not affect the matching, such as route('user.post.show',['id'=>1,'postId'=>10]); 3. Links can be directly embedded in the Blade template, such as viewing information; 4. When optional parameters are not provided, they are not displayed, such as route('user.post',

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.

Laravel's queue priority is controlled through the startup sequence. The specific steps are: 1. Define multiple queues in the configuration file; 2. Specify the queue priority when starting a worker, such as phpartisanqueue:work--queue=high,default; 3. Use the onQueue() method to specify the queue name when distributing tasks; 4. Use LaravelHorizon and other tools to monitor and manage queue performance. This ensures that high-priority tasks are processed first while maintaining code maintainability and system stability.
