Cannot generate library with the @nx/react generator and rspack as a bundler

[guitarooman14]

Current Behavior

I was just following the new Rspack documentation to migrate my current project from Webpack to Rspack and I tried to create a new library with the following command provided by this doc (Using @nx/rspack) :

nx g @nx/react:lib my-lib --bundler=rspack

And this is what I got :

$ nx g @nx/react:lib my-lib --bundler=rspack

 NX  Generating @nx/react:library
 NX  Property 'bundler' does not match the schema. 'rspack' should be one of none,vite,rollup.

Expected Behavior

The new library or application should be created and configure to use the rspack bundler.

The React Library Generator does not currently have rspack and option for bundler.

If your library is only going to be used internally in your workspace then you do not need to specify a bundler at all, and it will be bundled when the application is bundled.

Actually, I'm migrating some libraries from a current NX repository to another one in order to expose them to others projects. Moreover the new repository will just have a showcase application in order to show how to use those libraries so It will be helpful to use the @nx/react generator with the rspack configuration.

I wanted to test rspack because this application will use the module federation feature and I already have been struggle with the webpack implementation.

And by the way, I was just following the @nx/rspack documentation. So if I follow what you say, the documentation is wrong.

@guitarooman14 Indeed, the rspack documentation is incorrect. I'll update that to be correct.

The application can still use rspack and the libraries can use any bundler or no bundler.

When you say expose the libraries to other projects, do you mean via an npm package or via a Module Federation remote?

[guitarooman14]

I need to expose them via an npm package.
Basically I want to create publishable libraries with Rspack.

[Coly010]

In that case, you can use vite or rollup or wait until we add rspack support for it :)

Thanks for raising this!
