Summarize the reasons and solutions for the white screen or splash screen phenomenon when Vue jumps

Vue.js is a popular JavaScript framework widely used in front-end development. However, sometimes when using Vue.js, we encounter a problem: a brief white screen or splash screen will appear when jumping to the page. This article will describe the causes and solutions to this problem.

1. Reason

Vue.js is a single-page application (SPA) framework, which means that when we jump to the page, the page itself will not reload, but Content is dynamically loaded through JavaScript. Therefore, when we make a route jump in a Vue.js application, the browser loads JavaScript files and other resources, and these operations take time. During this brief period, the browser may display a white or splash screen.

2. Solution

In order to solve this problem, we can introduce some technologies and methods. Here are some solutions:

1. Preloading

Preloading is a technique that loads resources into the cache in advance. Through preloading, we can load JavaScript files and other resources in advance before the route jumps, so that there will no longer be a white screen or splash screen when the page jumps. In Vue.js, we can use the vue-meta-info plugin to support preloading. The plug-in provides a hook function beforeCreate, in which we can load resource files.

2. Optimize resource files

We can speed up loading by reducing the size of resource files. There are compression tools you can use to optimize files like JavaScript, CSS, and images. For example, you can use UglifyJS to compress JavaScript files, CSSnano to compress CSS files, and ImageOptim to optimize images. Note that when optimizing resource files, we want to ensure that we do not sacrifice the quality and functionality of the page.

3. Using lazy loading

Lazy loading is a technology that loads resource files only when needed. With lazy loading, we can delay the loading of unnecessary resources until they are actually needed. This helps reduce page opening time and speed up page loading. In Vue.js, we can use the vue-lazyload plug-in to implement lazy loading. This plug-in provides a directive v-lazy, which we can apply to images that need to be loaded lazily.

4. Loading progress bar

In order to reduce the impact of white screen or splash screen, we can use loading progress bar to provide a better user experience. You can use third-party libraries such as NProgress to create progress bars. In Vue.js, we can display the progress bar when the route jumps, and then hide the progress bar until all resources are loaded.

5. Optimize the server

Finally, we can also speed up page loading by optimizing the server. Caching technology can be used to reduce server load, and CDN accelerators can be used to speed up website access.

Conclusion

Vue.js jump flash is a common problem. In order to solve this problem, we can use technologies and methods such as preloading, optimizing resource files, lazy loading, loading progress bars, and server optimization. These methods help speed up page loading and provide a better user experience. Of course, according to the actual situation, we need to choose an appropriate method to solve this problem.
