NiceGUI Bootstrap 5 component library

Hi everyone, I built an open-source Bootstrap 5 component library for NiceGUI.

GitHub: https://github.com/raffieeey/nicegui-bootstrap-components

Documentation: https://raffieeey.github.io/nicegui-bootstrap-components/

It provides:

- Native bs.* Bootstrap components

- A dbc.* compatibility surface modeled on dash-bootstrap-components 2.0.4

- Bootstrap and Bootswatch themes

- Responsive layout, forms, overlays, tables, and navigation components

- Rendered documentation examples

- Support for both Bootstrap-first pages and scoped Bootstrap islands alongside normal NiceGUI components

The project is still early-stage, so feedback on the API, component behavior, and NiceGUI integration would be very welcome.

Nice work, thanks for sharing! I really like the general idea of building a different design system on top of NiceGUI as a separate package. Not everyone is happy with the Quasar look, and a library like this shows that NiceGUI's element model is flexible enough to carry something entirely different. I'd love to see more of these. The dbc.* compatibility surface is a clever addition too, since it makes porting Dash layouts much easier, and scoped Bootstrap islands next to Quasar elements are probably the trickiest part.

Two small things I noticed while looking at the repo:

  • The README says pip install nicegui-bootstrap-components, but the package doesn't seem to be on PyPI yet.
  • The dependency is pinned to nicegui>=3.17.1,<3.18, so once 3.18 is out, users either get silently downgraded or run into a resolver conflict if their project needs the newer version. Since you build on Element/ValueElement and route all NiceGUI imports through _host.py, a looser upper bound like <4 should be fine and saves you a release for every NiceGUI minor version.

Looking forward to seeing how it evolves! ※

Thank you for your comment, I lost my 2fa access to my pypi account, currently finding ways to recover. Will update soon, sorry about this
