npm install worker-loader
 

在vue.config.js文件的defineConfig里加上配置参数

  chainWebpack: config => {config.module.rule('worker-loader').test(/\.worker\.js$/).use({loader: 'worker-loader',options: {inline: true}}).loader('worker-loader').end()}

先在src目录下新建workers文件夹，接着在里面新建worker.js，在js文件里添加下面的测试代码：

addEventListener('message', e => {const { data } = econsole.log(data)setTimeout(() => {return postMessage('线程完成')}, 1000)
})
export default {}

测试

<template><div><h1>vue3-Worker</h1><button @click="openWorker">开启线程</button><p>F12打开浏览器控制台查看效果</p></div>
</template><script setup>
import Worker from 'worker-loader!@/workers/worker'
const openWorker = () => {const worker = new Worker()worker.postMessage('开启线程')worker.onmessage = e => {console.log(e.data)setTimeout(() => {worker.postMessage('线程关闭')worker.terminate()}, 1000)}
}
</script>
