SSR-safe, zero-config Web Workers integration for [Nuxt](https://nuxt.com).

> Web Workers enable running JavaScript code in the background to perform complex tasks without blocking the main thread, ensuring smoother and more responsive web applications.
>
> [Read more about Web Workers](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers).

- [✨  Changelog](https://github.com/danielroe/nuxt-workers/blob/main/CHANGELOG.md)
- [▶️  Online playground](https://stackblitz.com/github/danielroe/nuxt-workers/tree/main/playground)

## Features

- 🔥 SSR-safe usage of Web Workers
- ✨ auto-imported, zero-configuration
- 💪 fully typed
- 🕒 Automatic shutdown of workers after 1 second of inactivity

## Quick Setup

Install and add `nuxt-workers` to your `nuxt.config`.

```bash
npx nuxi@latest module add nuxt-workers
```

That's it! You can add web workers in your Nuxt app ✨

## Usage

Create your web worker in the `~/workers/` directory. It should export any utilities you want to be usable elsewhere:

```ts
// workers/hi.ts
export function hi() {
  return 'Hello from web worker!'
}
```

Then, call it in the rest of your Vue app.

```vue
<script setup lang="ts">
const message = await hi()
</script>

<template>
  <div>
    {{ message }}
  </div>
</template>
```

> [!TIP]
> Even if your function is synchronous, it will always become async when it is called within a worker because communication with a worker will always be asynchronous.

### Worker Auto-Shutdown

The module automatically shuts down workers after 1 second of inactivity to free up resources. This behavior ensures that your application remains efficient and responsive, without unnecessary resource consumption by idle workers.

## Roadmap

- [x] 📖 basic documentation
- [x] 🧪 client-side test
- [ ] 📦 webpack support
- [ ] ⚠️ type-level + dev warning if non serialisable args are passed
- [ ] 🤝 automatic shared workers with `.shared.ts` suffix
- [x] 💤 worker auto-shutdown

## 💻 Development

- Clone this repository
- Enable [Corepack](https://github.com/nodejs/corepack) using `corepack enable`
- Install dependencies using `pnpm install`
- Stub module with `pnpm dev:prepare`
- Run `pnpm dev` to start [playground](./playground) in development mode
