vue3使用particles外掛實現粒子背景的方法詳解

npm install particles.vue3

import { createApp } from 'vue'
import App from './App.vue'
import router from "./router";
import Particles from "particles.vue3"; // 引入
 
const app = createApp(App);
 
app.use(router).use(Particles).mount("#app");

<template>
	<div class="box">
		<Particles id="tsparticles" class="login-partic" :options="options" />
	</div>
