Article Introduction：In a React form, controlled components use React state to manage data, while non-controlled components rely on DOM to process data. 1. The controlled component controls the input value through the state. Each user input will trigger the event update status and can verify or format the data in real time; 2. The uncontrolled component uses ref to obtain the DOM value, which is suitable for obtaining data only when submitting or integrating with third-party libraries; 3. The selection is based on whether the form data needs to be fine-grained and real-time interaction.

Article Introduction：The default slot is used to insert a single content, and the content passed by the parent component will be directly filled in the location of the child component; 2. The named slot implements multiple insertion points through the name attribute and v-slot instructions, so that the content can be inserted into different areas of the child component; 3. The scope slot allows the child component to pass data to the parent component through the slot prop. The parent component can custom render content based on this data, thereby achieving logical separation from display. Slots are the core mechanism in Vue to realize content distribution and flexible reuse of components.

Article Introduction：In Vue2, .native is a modifier used to listen for native events of the component root element. It is suitable for scenarios where native DOM events need to be directly bound, such as clicking on component containers, processing form input underlying events, or achieving special interactive effects. 1. Native can only be used on custom components, not ordinary HTML tags; 2. If the component has multiple root nodes, .native will be invalid; 3. Not all events are suitable for use with .native, and some interfaces should be exposed through $emit. Alternatives include: listening within the component and throwing events from $emit, batch binding using v-on object syntax, and avoiding multiple nodes to support .native. Although .native is convenient, it is recommended to use $e first.

Article Introduction：The Container component is responsible for data logic, and the Presentational component is responsible for UI display. Specifically: 1. The Presentational component receives props and renders the UI, focusing on the display form; 2. The Container component processes data acquisition, state management and event logic, and passes data to the display component. Distinguishing between the two can help separate responsibilities, improve reusability and testing convenience. Although Hooks no longer need to be strictly split after they appear, it is still valuable to implement similar features through custom Hooks in complex projects. The methods of judgment include whether to use Redux, calling APIs, or processing business logic, etc. Exceptions can be handled flexibly without forced splitting.

Article Introduction：There are four main ways to create custom validation rules in Laravel. First, use Rule objects to add complex conditions, such as combining database queries and ignore methods to achieve unique verification; second, encapsulate custom logic in form requests, and reuse and clear structure by rewriting rules() method; third, use closures to write instant rules, suitable for simple judgment scenarios; fourth, create custom rule classes to make the organization clearer and easier for testing and team collaboration. Developers should choose appropriate verification methods based on specific business scenarios to improve code maintainability and development efficiency.

Article Introduction：Vue custom directive is a mechanism for encapsulating repetitive DOM operations, suitable for scenarios where component logic cannot meet the needs and directly operates the DOM. It realizes functions such as focusing input frames, permission control, scrolling behavior processing, etc. through hook functions of instruction objects (such as mounted and updated). Common usage examples include: 1. Automatic focus input box (v-focus); 2. Permission control command (v-permission), determining whether to remove elements based on user permissions; 3. Scroll behavior processing command (v-scroll), triggering data loading or animation through IntersectionObserver API. It should be noted that custom directives should not replace component logic and avoid

Article Introduction：The design system is implemented using Vue components, first defining the design token, then building a reusable Vue component, then creating a usage guide, and finally integrating it into the project. The first step is to set the tokens such as colors, fonts, spacing, etc., and store them in CSS variables or JS files; the second step is to create a basic component such as BaseButton that is unified naming and behavior based on the token, and use documents and tools such as Storybook for testing; the third step is to write detailed instructions on using components, including component application scenarios, form structures and examples; the fourth step is to package the component library into an NPM package or place it in a single warehouse, register global components through plug-ins and formulate code specifications to ensure smooth version control and team collaboration.

Article Introduction：Laravel provides a variety of advanced data verification technologies, including encapsulating complex logic using custom rule objects, reusing verification rules using form requests, implementing conditional verification through sometimes methods, and uniqueness checking in combination with database rules. First, create a custom rule class through make:rule and define logic in passes() and message() methods, so complex verification such as age limit can be achieved; second, create a form request class using make:request to separate the verification logic and directly inject it into the controller to improve the code organization structure; third, call the sometimes() method to dynamically decide whether to verify a certain field based on the input value, which is suitable for dynamic forms

Article Introduction：The Element-UI cascading drop-down box realizes parent-child component communication through custom events: the parent component listens to the change event issued by the child component and obtains the selection result. The handleChange method is used to handle selection logic and can perform different operations based on hierarchical differences. In order to obtain intermediate process information, you need to customize events inside the cascading selection box, and one event is triggered at each selection level. For large data sets, it is necessary to optimize the data loading method and use packaging components for complex logic processing. Code readability and maintainability cannot be ignored, and clear naming and annotation can help with post-maintenance.

Article Introduction：TypeScript Tips: Extend HTML Element Properties This article is excerpted from "Releasing the Power of TypeScript", which will show you how to extend the properties of HTML elements in TypeScript. In large applications, we often build components based on standard HTML elements, such as custom buttons, or components that combine tags and input fields. TypeScript requires explicit definition of properties accepted by components, which can be cumbersome for each property. To match the properties used by HTML elements in React, you can use React.ComponentProps. To exclude certain properties, you can use the Omit utility type. To extend the properties of the component, you
