Use for Web Workers in Bun, worker_threads, parallel processing, and background tasks.
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
# Bun Workers
Bun supports Web Workers and Node.js worker_threads for parallel execution.
## Web Workers
### Basic Usage
```typescript
// main.ts
const worker = new Worker(new URL("./worker.ts", import.meta.url));
worker.postMessage({ type: "start", data: [1, 2, 3, 4, 5] });
worker.onmessage = (event) => {
console.log("Result:", event.data);
};
worker.onerror = (error) => {
console.error("Worker error:", error.message);
};
// worker.ts
self.onmessage = (event) => {
const { type, data } = event.data;
if (type === "start") {
const result = data.map((x) => x * 2);
self.postMessage(result);
}
};
```
### Worker with URL
```typescript
// Import from file path
const worker = new Worker(new URL("./worker.ts", import.meta.url));
// Or with blob URL
const code = `
self.onmessage = (e) => {
self.postMessage(e.data * 2);
};
`;
const blob = new Blob([code], { type: "application/javascript" });
const worker = new Worker(URL.createObjectURL(blob));
```
### Transferable Objects
```typescript
// main.ts
const buffer = new ArrayBuffer(1024 * 1024); // 1MB
const view = new Uint8Array(buffer);
view.fill(42);
// Transfer ownership (zero-copy)

How to install
mdr add secondsky/claude-skills/bun-workers@sha256:7867fa269306f32dThe line at the top of this page pins the label v1.0.0, 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.
