ReactPy
Python library for building user interfaces from components, without writing JavaScript.
ReactPy is a Python library for building user interfaces out of components, without writing JavaScript. The documentation describes its components as similar to those in ReactJS. It is installed with pip alongside one of its native backends: Starlette, FastAPI, Flask, Sanic or Tornado. Django, Jupyter and Plotly Dash are reached through separate packages.
Worth knowing
The running guide says the development server started by run() suits testing, and that a production deployment runs the application under an ASGI or WSGI server from the command line. The server then stays running on the host.
The documentation site says it is still under construction.
