Feature Request: RSBuild Plugin Support for AnyWidget

[Roy-Kid]

I recently switched from Vite to Rspack and was pleasantly surprised to see that AnyWidget has also migrated to Rspack. Given this transition, I wanted to ask if it would be possible to provide an RSBuild plugin similar to the existing Vite plugin. This would enhance the developer experience and streamline the integration process for projects using RSBuild.
Thank you for considering this request!

@Roy-Kid Interesting idea! We've migrated partially to rspack in order to build the front end Jupyter extension for the anywidget Python package because JupyterLab requires traditional widgets to be packaged using Module Federation v1. This allowed us to drop the custom jlab extension build dep which was based on Webpack and required more build-system dependencies.

That said, I don't think I'm familiar enough with RSBuild to know what an RSBuild plugin for anywidget would look like. The Vite plugin was created before we had our own built in HMR, and it's proven challenging to maintain as the notion of developing with Vite within an existing app (i.e., JupyterLab) is not straight forward.

Thanks for your reply! I'm a beginner in front-end development, and I find Rspack's manual easier to understand. I'll keep learning, and if I come across a good practice with Rspack, we can discuss it further on Discord!

Sweet, thanks for starting the discussion!
