Use of particles.js
Install particles.js globally
npm install --save particles.js
Configure particles.js to
import the particles.js file.
When your scope of use is relatively small, you can directly import it in the script of the current vue file
//vue单文件
import particles from 'particles.js'
When the scope is large, you can import it globally, and import it in main.js
import particles from 'particles.js'
Vue.use(particles)
I create a particles.json in the asset folder

Define a div in the template
<div id="particles"></div>
Configure in script
// 引入particles.json文件用于配置canvas
import particlesJson from '../assets/particles.json'
export default {
name: 'particlesDemo',
mounted(){
// particles是我们设置的id，particlesJson是我们引入的json文件
particlesJS('particles', particlesJson,);
}
}
Set in style
#particles{
position: absolute;
width: 100%;
height: 100%;
background-color: #000000;
background-repeat: no-repeat;
background-size: cover;
background-position: 50% 50%;
}
The final rendering effect is as follows:
Bugs encountered
1. Introduced according to the official document, the effect did not come out, the official document introduced the code as follows
mounted(){
particlesJS.load('id','path to your particles.data');
}
Solution:
Just delete .load
mounted(){
particlesJS('id','path to your particles.data');
}
2. The effect came out, but the style of json I configured did not go up.
Solution: The
path cannot be placed in particlesJS, imported from the outside, and assigned to it.
import particlesJson from '../assets/particles.json'
mounted(){
particlesJS('id',particlesJson );
}
