用于将昂贵的浏览器工作移出主线程，涉及 Web Workers、SharedWorker、worker 池、Comlink、transferable objects、Vite/Webpack worker 集成或 UI 响应性修复。不要用于轻量同步工作或 DOM 操作；中文触发词包括 Web Worker、后台线程、主线程阻塞。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web Workers ## 用途 把昂贵计算移出主线程，保持输入、滚动和动画响应。 ## 流程 1. 先确认瓶颈：任务超过约 10ms、用户输入延迟明显、FPS 下滑或大文件解析/图像处理/加密计算才考虑 Worker。 2. 选择通信模型：简单任务用 `postMessage`，函数式 RPC 用 Comlink，大量并行小任务用 Worker pool，跨 Tab 同步用 SharedWorker。 3. 设计消息协议：请求/响应类型、错误类型、取消或超时策略都要明确。 4. 传大对象时优先 Transferable Objects；不要让结构化克隆吞掉 Worker 带来的收益。 5. 在组件或页面卸载时 `terminate()`，并通过 Profiler、Performance 面板或 FPS 指标验证主线程改善。 ## 详细参考 - 需要原生 Worker 文件、构建工具导入、React 生命周期封装和清理示例时，加载 [references/basic-worker.md](references/basic-worker.md)。 - 需要 Transferable Objects、Comlink、Worker pool、SharedWorker、CSP 和 SharedArrayBuffer 注意事项时，加载 [references/advanced-workers.md](references/advanced-workers.md)。 ## 约束 - Worker 内不能访问 DOM、`window`、`document`、`alert()` 或同步 `localStorage`。 - 高频通信可能比主线程计算更慢；先测量再拆分。 - Worker 文件必须同源加载，并受 `worker-src` CSP 限制。 - 大型二进制数据优先 transfer，transfer 后原引用会失效。 - 每个 Worker 有独立 JS 堆，必须主动管理生命周期和内存。 ## 预期输出 计算密集型操作在后台线程执行，主线程输入和滚动恢复流畅，错误与取消路径明确，Worker 在卸载时被终止且无内存泄漏。

How to install
mdr add bovinphang/frontend-craft/fec-web-workers@sha256:73946e82d72dc807The line at the top of this page pins the label git:20260611.9d7f5e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
