Detailed explanation of how to create routing page in Vue project

The core of creating reusable components in Vue is to understand component structure, props usage, and logical encapsulation. 1. Clarify component responsibilities and input and output, such as defining props and update:modelValue events that receive label, placeholder, modelValue; 2. Extract styles and structures, and improve universality through class, style attributes or slots; 3. Use slots to support custom content, such as allowing label slots to pass in rich text; 4. Extract public logic into combination functions, such as encapsulating verification logic with useInputValidation to enhance component scalability and reusability.

Writing unit tests ensures that Vue components behave correctly, and using Vitest and VueTestUtils can effectively complete the test. 1. First install Vitest and VueTestUtils, and configure the environment as jsdom in vite.config.js to support DOM operations; 2. Use the mount method to mount components and pass in props for rendering tests; 3. Use trigger method to simulate user interaction and use emitted to detect event triggers; 4. Use flushPromises for asynchronous logic to wait for updates before making assertions.

The steps to obtain data using Axios in Vue components are as follows: 1. Install Axios; 2. Introduce and use Axios to initiate GET requests in the component; 3. Use life cycle hooks to trigger requests; 4. Handle asynchronous operations and state management; 5. Display content based on status in the template. First, install Axios through npm or yarn, then import and configure the data request method in the script part of the component, call the request function using the created hook, use async/await to process the asynchronous process, and set loading and error status to improve the user experience. Finally, in the template, use v-if, v-else-if and v-else instructions to display according to different statuses.

v-once is a directive in Vue for optimizing static content rendering and is suitable for content that does not require responsive updates. 1. V-once can be used to avoid repeated renderings such as "User Agreement"; 2. Static text such as registration page precautions are suitable for adding this instruction; 3. V-once can also be used to improve performance when loading data at one time. Rational use can improve page rendering efficiency, but it should be noted that it is irreplaceable for conditional rendering and should not be abused.

The methods to test the router navigation function include: 1. Confirm whether you can log in to the router background normally, enter the default IP address such as 192.168.0.1 or 192.168.1.1, check whether the login box pops up and try to log in with the default account; 2. Test whether each menu page can be opened and redirected normally, and ensure that there are no errors or loading problems on the wireless settings, security settings and other pages; 3. Verify whether the form submission and saving are valid, such as modifying the Wi-Fi name or password and saving and checking whether it is effective; 4. Optionally test whether the mobile access is friendly, and check whether the page layout and operation are normal when accessing the mobile browser. During the test process, you need to pay attention to saving the settings and restarting the router as needed to ensure that the changes take effect.
