# svelte-worker

> **POC: DO NOT USE THIS**

A svelte preprocessor that takes a function call that is assigned to a value in a reactive declaration and delegates that work to a web worker.

```svelte

  import marked from "marked";

  export function parse(source) {

    if (!source) return;

    return marked(source);

  }

  import { markdown } from "./markdown.js";

  worker: text = parse(markdown);

```

This preprocessor only supports the simple assignment of a call expression (`x = some_func(val)`), it does not support any kind of boolean expression typical of reactive declarations (`x = y && some_func(val)`).

Any function that is delegated to a worker must be exported from the module script. The worker is inlined and not written to a separate file (`new Worker(URL.createObjectURL(new Blob([src])))`). The preprocessor bundles for now but could make use of `type: module` workers, support was only recently added to chrome so this may not be feasible for some time.

There are many questions.

The implementation is very rough.

Do not use this.
