How can I use unified inside a web worker

[matfire]

Hey all,

Hopefully this is the right org for this question...

Like the title says, is there a way to run a unified parser inside a web worker ? I am using Vite with React, if it helps.

If I try to run a simple parser with remarkParse, remarkRehype and rehypeStringify, I get the following error:

Uncaught ReferenceError: document is not defined

Is this not a supported environment? Or am I doing something wrong?

Unified v11.0.5

Welcome @matfire 👋
This sounds the same as https://github.com/orgs/remarkjs/discussions/1083
In particular @remcohaszing's proposed work around for vite choosing the browser versions of the dependency in https://github.com/orgs/remarkjs/discussions/1083#discussioncomment-4347349

Hi @ChristianMurphy 👋 ,

thanks for the quick reply! I checked it out and it looks like that's the culprit (or, specifically the module decode-named-character-reference ). For some reason, Vite is not importing the correct export (maybe the file is somehow not marked as a worker file and is bundled with the rest of the app ?). I asked this on the Vite discord, currently waiting for a reply
