The life cycle hook of the Vue component is used to execute code at a specific stage. 1.created: Called immediately after the component is created, suitable for initializing data; 2.mounted: Called after the component is mounted to the DOM, suitable for operating the DOM or loading external resources; 3.updated: Called when the data update causes the component to be re-rendered, suitable for responding to data changes; 4.beforeUnmount: Called before the component is uninstalled, suitable for cleaning event listening or timer to prevent memory leakage. These hooks help developers accurately control component behavior and optimize performance.

To implement reusable Vue paging components, the following key points need to be clarified: 1. Define props including the total number of lines, the number of lines per page and the current page number; 2. Calculate the total number of pages; 3. Dynamically generate the displayed page number array; 4. Process the page number click event and pass it to the parent component; 5. Add styles and interaction details. Receive data through props and set default values, use the computed attribute to calculate the total number of pages, use the method to generate the currently displayed page number array, render buttons in the template and bind click events to trigger the update:current-page event, listen to the event in the parent component to update the current page number, and finally highlight the current page number through CSS and control the button status to improve the user experience.

To enable v-model in Vue custom component, you need to: 1. Declare modelValueprop; 2. Notify the parent component data changes through $emit('update:modelValue'). For example, bind modelValue in input and trigger an event. If you need to support multiple v-models (Vue3), you can use naming methods such as v-model:title and declare the corresponding prop and emit. When maintaining variables internally, it is recommended to use data or computed for intermediate layer synchronization to avoid directly modifying props.

For Vue developers, a high-quality finished project or template is a powerful tool to quickly start new projects and learn best practices. This article has selected multiple top Vue free finished product resource portals and website navigation for you to help you find the front-end solutions you need efficiently, whether it is a back-end management system, UI component library, or templates for specific business scenarios, you can easily obtain them.

Testing asynchronous operations in Vuex requires the following steps: 1. Use done() or return Promise to ensure that the test waits for the asynchronous operation to complete; 2. Use tools such as jest.spyOn to simulate API calls to avoid dependence on the real interface; 3. Verify whether the error handling logic is working properly; 4. Pay attention to the correct use of async/await to prevent uncaught exceptions. These methods can effectively ensure the reliability and testability of asynchronous code.

The method of using .env files in Vue projects is as follows: 1. Create .env files in the project root directory and add corresponding files according to the environment, such as .env.development, .env.production, etc.; 2. Define variables with VUE_APP_ as the prefix in the file, such as VUE_APP_API_URL=https://api.example.com; 3. Access variables through process.env.VUE_APP_API_URL in the code, and can also be used for dynamic configuration in vue.config.js; 4. Automatically load corresponding environment variables when running different commands, such as npmrunserve loading development environment variables.

$ref is a keyword used to reference other parts of a JSON or YAML configuration file or external file structure, commonly found in JSONSchema and OpenAPI specifications. 1. The basic syntax of $ref is {"$ref":"path"}, which can point to the internal inside of the current document (such as #/definitions/User) or external files (such as user-schema.json#/definitions/User). 2. Usage scenarios include reusing schemas, splitting large files, and organizing code structures. 3. Note that the path must be correct, avoid circular references, ensure that external files are accessible, and avoid excessive nesting.
