How do I apply middleware to a specific route or route group?
There are three ways to apply middleware to a specific route in Express.js: 1. Add middleware to a single route and insert middleware functions directly into the .get or .post method; 2. Apply middleware uniformly to a group of routes, use express.Router() to create a subroutine group and apply middleware on it; 3. Dynamically determine whether middleware is enabled, and flexible control is achieved by adding conditional logic inside the middleware. These three methods are applicable to single paths, modular routing groups, and scenarios that require dynamic judgment, and pay attention to the middleware execution order and path matching rules.

How do I use components in Blade templates? (@component)
Components in the Blade template realize efficient reuse of HTML code segments and pass dynamic data through the @component directive. To use @component, you need to create a component view file (such as resources/views/components/alert.blade.php) and pass in the associative array data through the @component directive. For example: define the alert component to receive $type and $message variables, use @component('components.alert',['type'=>'success','message'=>'Ope in the main view

What are route groups, and how are they used?
The core role of a routing group is to control the delivery path of a call or packet, especially when multiple levels of failover or multipath selection are required. It is called in the set order as a container for a group of gateways. If gateway A is not available, try gateway B; the creation steps include adding gateways, setting order, and associating routing lists; the routing list acts as a dispatcher to decide how to use gateways in the routing group to achieve flexible strategies, such as master-slip switching; common application scenarios include outbound call failover, routing selection by time period or number prefix, and traffic sharing; when configuring, you need to pay attention to the gateway activation status, priority order, correctly binding the routing list and sufficient testing.

How do I create forms in Yii?
The core process of creating a form in the Yii framework includes four steps: 1. Create a model class, define fields and verification rules; 2. Process the form submission and verification logic in the controller; 3. Render form elements in the view using ActiveForm; 4. Pay attention to CSRF protection, layout and style configuration. The model class sets the required items and data formats through the rules() method. The controller uses load() and validate() to process the submitted data. The view uses ActiveForm to automatically generate input boxes with labels and error prompts, and can customize the layout and styles, thereby achieving a complete form system.
