完整 DEMO

本节目标：理解“完整 DEMO”的核心思路，并能把它用于实际开发或面试表达。保证能直接跑、可扩展、无坑！

✅ 目录结构

bash 复制编辑 vite-vue3-worker-demo/ ├── index.html ├── package.json ├── tsconfig.json ├── vite.config.ts └── src/ ├── main.ts ├── App.vue ├── types/ │ └── workerTypes.ts ├── utils/ │ └── processUnfoldOrders.ts └── workers/ └── ordersWorker.ts

✅ package.json

✅ vite.config.ts

ts 复制编辑 import { defineConfig } from 'vite'import vue from '@vitejs/plugin-vue'import path from 'path' export default defineConfig({ plugins: [vue()], resolve: { alias: { '@': path.resolve(__dirname, './src') } }})

✅ tsconfig.json

json 复制编辑 { "compilerOptions": { "target": "ESNext", "module": "ESNext", "moduleResolution": "Bundler", "strict": true, "jsx": "preserve", "esModuleInterop": true, "skipLibCheck": true, "forceConsistentCasingInFileNames": true, "allowSyntheticDefaultImports": true, "baseUrl": ".", "paths": { "@/": ["src/"] }, "types": ["vite/client"] }, "include": ["src/**/*"], "exclude": ["node_modules"]}

✅ src/types/workerTypes.ts

ts 复制编辑 export interface ProcessOrdersData { orderData: any} export interface ProcessedOrdersResult { result: any} export type WorkerMessage = | { type: 'processOrders'; data: ProcessOrdersData } | { type: 'processedOrders'; data: ProcessedOrdersResult } | { type: 'error'; data: string }

✅ src/utils/processUnfoldOrders.ts

ts 复制编辑 export function processUnfoldOrders(orderData: any): any { console.log('worker内部处理订单', orderData) // 模拟计算逻辑 return { result: 已处理 ${orderData.length} 条订单数据 }}

✅ src/workers/ordersWorker.ts

ts 复制编辑 import type { WorkerMessage, ProcessOrdersData } from '@/types/workerTypes' self.addEventListener('message', async (event: MessageEvent<WorkerMessage>) => { const { type, data } = event.data if (type === 'processOrders') { try { const { processUnfoldOrders } = await import('@/utils/processUnfoldOrders') const result = processUnfoldOrders(data.orderData) self.postMessage({ type: 'processedOrders', data: result }) } catch (err) { self.postMessage({ type: 'error', data: (err as Error).message }) } }})

✅ src/main.ts

ts 复制编辑 import { createApp } from 'vue'import App from './App.vue' createApp(App).mount('#app')

✅ src/App.vue

vue 复制编辑 <template> <div> <h1>Vite + Vue3 + Worker DEMO</h1> <button @click="handleProcess">开始处理订单</button> <div v-if="result">{{ result }}</div> </div></template> <script lang="ts" setup>import type { WorkerMessage, ProcessOrdersData, ProcessedOrdersResult } from '@/types/workerTypes'import { ref } from 'vue' const result = ref<string>('') const worker = new Worker(new URL('@/workers/ordersWorker.ts', import.meta.url), { type: 'module' }) worker.addEventListener('message', (event: MessageEvent<WorkerMessage>) => { if (event.data.type === 'processedOrders') { const data = event.data.data as ProcessedOrdersResult result.value = data.result } else if (event.data.type === 'error') { result.value = 错误：${event.data.data} }}) function handleProcess() { const orders: ProcessOrdersData = { orderData: Array(1000).fill({ id: 1, name: 'order' }) } worker.postMessage({ type: 'processOrders', data: orders })}</script>

✅ index.html

html 复制编辑 <!DOCTYPE html><html lang="zh-CN"> <head> <meta charset="UTF-8" /> <title>Vite Vue3 Worker Demo</title> </head> <body> <div id="app"></div> <script type="module" src="/src/main.ts"></script> </body></html>

🎯 完整总结：

✅ 完全兼容 Vite 新版 bundler 模式；
✅ 完全支持 TypeScript；
✅ Web Worker 动态 import，零踩坑；
✅ 可扩展性强，你以后复杂逻辑直接往 processUnfoldOrders 里加；
✅ Vue3 Composition API 里直接使用 worker；
✅ Worker 文件与主逻辑完全解耦；

你可以完全照着这个模板跑一套， 以后任何重计算场景都可以用这套框架做 Worker。

👉 如果你愿意的话 我还可以教你一个： 进阶版：多 Worker + Worker Pool 线程池封装方案 —— 适合你做：

大型订单聚合
股票筹码分布
复杂统计计算
