When building a web application using Vue.js, page updates not displayed may be one of the problems developers often encounter. This is a very common problem, but it can usually be solved easily. In this article, we'll look at some of the reasons why page updates may not be showing up and provide solutions.

When this happens, you can try using the Vue Developer Tools to check for changes in component state and make sure they have been updated correctly. If the component state is not updating correctly, you need to inspect the code and find out what the problem is.
The hook function in Vue is a function that performs some operations, such as executing the mounted function when the component is created, etc. If the hook function is not executed correctly, it may cause page updates not to be displayed. This is usually due to coding issues. You can print some logs in the component to check if the hook function is executed correctly.
If your Vue app uses routing, routing issues may be another reason why the page is not updating correctly. When working with routing, you need to ensure that the routing is configured correctly and that changes to the routing state are synchronized with the component state. Also, if you are using dynamic routing, you will also need to ensure that the dynamic parameters are passed correctly.
