Refresh after vue modification

As front-end developers, we all know that Vue.js is a very popular JavaScript framework that is maintained by a large and active community. The biggest advantage of Vue.js is that it is easy to use and develop quickly. However, during the development process, sometimes you will encounter a puzzling problem, that is, after modifying the Vue code, the page will not refresh. At this time we need to use some techniques to solve this problem.

The following are several ways to solve the problem of Vue not refreshing the page after modification:

1. Manually refresh the page

This is the most basic method. Just refresh the page manually. Although this method is simple, it often requires us to waste time, especially when we face large projects. When you feel that the problem is not solved, but you have to continue working, this method can still solve the problem for you.

2. Enable Hot Reload in development mode

Vue.js has a feature called Hot Reload in development mode, which can automatically refresh the page and make our modifications Effective immediately. Enabling Hot Reload in development mode can greatly reduce the number of manual page refreshes. You only need to add the --hot parameter after the command to start the development server to enable the hot reload function.

For example, a project created using Vue CLI can start the development server with the following command:

vue-cli-service serve --hot

If your project is not built using Vue CLI, you can enable Hot by modifying the Webpack configuration file Reload, for specific methods, please refer to the Vue.js official documentation (https://vue-loader.vuejs.org/zh/guide/hot-reload.html).

3. Use Chrome DevTools for debugging

Chrome DevTools is a very powerful development tool that can help developers quickly locate and solve problems. During Vue.js development, you can use Chrome DevTools for debugging. You can open the Components tab in the console, and then when modifying the Vue component, you can see the page changes in real time.

4. Debugging with Vue DevTools

Vue DevTools is a browser extension that can help us conveniently debug Vue applications in Chrome or Firefox. An important feature in Vue DevTools is the "live editor", which allows us to preview the modified code in real time, and the page will refresh automatically. You can download and install this extension from the Chrome Web Store or Firefox Extension Store.
