We created https://htpy.dev to solve this for our Django app. Has been using it in production for multiple years. Works great with Django (or any Python web framework).

This had me checking if anyone has implemented first-class support for Python JSX components in Django yet, and it could be... sort of... maybe viable with PyJSX? [1]

It looks like you'd have to implement something equivalent to provider/context functionality yourself if you want it, as well as a simple render()-like helper to render a component tree. I've not tried their VS Code plugin, but it's a good sign that they have one.
