How to handle page skeleton and loading animation in Vue

How to handle the skeleton and loading animation of the page in Vue requires specific code examples

When developing web applications, the loading speed of the page is a very important factor. Fast loading pages can not only improve user experience, but also effectively increase user retention rate. In the Vue framework, we can optimize the page loading process and provide users with a better experience by using page skeletons and loading animations.

Page skeleton refers to providing a pre-designed interface framework to fill the blank area of the page before the page data is loaded, so that users can have a general understanding of the structure and layout of the page. The loading animation shows a dynamic effect to the user during the page data loading process to remind the user that the page is loading and increase the user's patience and waiting time.

Below, I will use code examples to introduce how to handle the page's skeleton and loading animation in Vue.

First, we need to install thevue-content-loaderplug-in, which can be used to generate the code for the skeleton screen. Run the following command in the terminal:

npm install vue-content-loader

Next, introduce and registervue-content-loaderin the component where you need to add a skeleton screen:

// 引入vue-content-loader import ContentLoader from 'vue-content-loader' export default { // 注册ContentLoader组件 components: { ContentLoader }, // ... }

Next , use theContentLoadercomponent in the template, and define the style and layout of the skeleton screen:

In the above code, we use theContentLoadercomponent to create a 300x200px Skeleton screen usesrectelements to define the style and layout of the skeleton screen.primaryColoris used to define the primary color,secondaryColoris used to define the secondary color.

Next, let’s introduce how to add loading animation in Vue.

First of all, we can use thev-ifinstruction provided by Vue to control the display and hiding of the loading animation. We can control the display and hiding of loading animation by defining aisLoadingattribute in the data. When the data is loaded, set theisLoadingproperty tofalseand the loading animation will disappear.

Next, in the component where loading animation needs to be added, you can use Vue's calculated properties to show or hide the loading animation based on the value ofisLoading.

export default { data() { return { isLoading: true, // 数据是否正在加载中 data: null, // 数据 } }, computed: { showLoadingAnimation() { return this.isLoading ? 'loading-animation' : 'data-content' }, }, // ... }

In the template, we can use thev-ifdirective to control the display and hiding of the loading animation based on the value of the calculated propertyshowLoadingAnimation.

In the above code, we wrap the loading animation with thedivelement, and decide whether to display the loading animation or the data content based on the value ofshowLoadingAnimation.

To sum up, by using the plug-ins and instructions provided by the Vue framework, we can easily add skeleton screens and loading animations to the page to improve the loading speed and user experience of the page. I hope this article can help you understand how to handle the skeleton and loading animation of the page in Vue.
