I’m curious about this too, The Databricks blog on general availability (GA) mentions "Bring-your-own-framework," but the documentation it links to only covers Python-based frameworks like Streamlit, Dash, and Gradio (docs)

From what I’ve found, based on the Python runtime, you might be able to host a FastAPI server, mount a built React project as static files, and deploy it as a Databricks App

• Building Databricks Apps with React and Mosaic AI Agents (blog)
• Databricks Apps Cookbook FastAPI (cookbook)

Has anyone tried this or found a better way to deploy a React frontend on Databricks Apps? I’d love to hear about your approach or if it’s even feasible.

Thanks

A React frontend can be used with a Python backend. If you're referring to node.js support, this is coming soon, stay tuned.

A colleague of mine is trying the same. React and mesop to have better control on the frontend while accessing the dashboard. WIP. 

Here is some new documentation for using node.js with Databricks apps.
