Skeleton loaders are a popular UI pattern used to indicate that content is loading. They provide a placeholder that mimics the layout of the content that will eventually be displayed, enhancing the user experience by reducing perceived loading times. In a Next.js application, implementing skeleton loaders can be achieved through various methods, including using CSS, libraries, or custom components. Below, I will outline the steps to create skeleton loaders, best practices, and common mistakes to avoid.
To create skeleton loaders in a Next.js application, you can follow these steps:
One of the simplest ways to implement a skeleton loader is by using CSS. You can create a skeleton loader component that uses CSS animations to simulate loading.
import React from 'react';
import styles from './SkeletonLoader.module.css';
const SkeletonLoader = () => {
return (
);
};
export default SkeletonLoader;
In your CSS file (SkeletonLoader.module.css), you can define the styles:
.skeleton {
padding: 20px;
background: #e0e0e0;
border-radius: 4px;
}
.title {
width: 60%;
height: 20px;
background: #c0c0c0;
margin-bottom: 10px;
animation: pulse 1.5s infinite;
}
.line {
width: 100%;
height: 10px;
background: #c0c0c0;
margin-bottom: 5px;
animation: pulse 1.5s infinite;
}
@keyframes pulse {
0% {
opacity: 1;
}
50% {
opacity: 0.5;
}
100% {
opacity: 1;
}
}
For more complex applications, you might want to use a library like react-content-loader. This library provides a set of customizable SVG-based skeleton loaders.
import React from 'react';
import ContentLoader from 'react-content-loader';
const MyLoader = () => (
);
export default MyLoader;
By following these guidelines, you can effectively implement skeleton loaders in your Next.js application, improving the user experience during content loading.
