Used Package Manager

npm

Expected Behavior

I would like to implement a Remix app where one of the routes loads a federated module.
In the linked repo:

• package remix-host: the page mfe.tsx at route /mfe will load a federated module
• package remote: the module exposes a simple React component via module federation

I was expecting the npm run build command to complete successfully and at runtime the federated component to be consumed properly by the Remix host app

Actual Behavior

The command npm run build fails with the following error

The RR7 Rsbuild plugin might be a better option since it has first-class module federation support. web-infra-dev/rsbuild#4186

[ScriptedAlchemy]

Yes, Ive also designed the implementation specifically to support federation.
Note its not yet done, i need to ask Jacob a few more questions tomorrow - and smooth out a few other areas, as well and pull over a few more of remix conventions. But its pretty close
