关于VueCli项目中如何加载调试Worker和SharedWorker

news 2025/9/4 9:17:10

安装Webpack插件

VueCli 项目中默认是没有加载 worker 的配置，需要额外安装 webpack 插件来实现，让我们开始安装 worker-loader 插件

# npm
npm install worker-loader
# pnpm
pnpm install worker-loader
# yarn
yarn add worker-loader

配置Webpack插件

然后我们开始配置 vue.config.js 增加下面配置

{// ...chainWebpack: config => {// 配置 worker-loader 插件，匹配处理 *.worker.js 文件config.module.rule('worker').test(/\.worker\.js$/).use('worker-loader').loader('worker-loader').tap(() => ({ worker: 'SharedWorker' })).end();// 排除 *.worker.js 解决无法热更新问题config.module.rule('js').exclude.add(/\.worker\.js$/);}// ...
}

编写SharedWorker

然后我们在 src/* 任意目录下创建 *.worker.js 文件，例如 src/test.worker.js

// path: src/test.worker.js
const ports = [];
onconnect = (event) => {const port = event.ports[0];ports.push(port);port.onmessage = (event) => {const data = event.data;console.log('[Main] 收到消息', event.data);// 关闭连接if (data === 'close') {const index = ports.findIndex(vo => vo === port);index > -1 && ports.splice(index, 1);}// 测试连接if (data === 'ping') {port.postMessage('ok');}// 广播消息if (data === 'broadcast') {ports.forEach((vo) => vo.postMessage('say'));}};
};

编写App.vue

然后我们在应用中去初始化 src/test.worker.js 并测试调用

// path: src/App.vue
import TestWorker from './test.worker.js';export default {// ...created() {const worker = new TestWorker()worker.port.start();worker.port.onmessage = (event) => {console.log('[Main] 收到消息', event.data);};setTimeout(() => {worker.port.postMessage('ping');}, 1000);setTimeout(() => {worker.port.postMessage('broadcast');}, 2000);// 监听当前页面关闭主动销毁端口window.addEventListener('beforeunload', () => {worker.port.postMessage('close');});}// ...
};
