Welcome! But…but…why? What advantages do you expect Phoenix (Live)Views will bring you in this use case? If we know, this might influence the advice.
Option 1: less Python
Phoenix can act as API server. You could swap Django with Phoenix + Absinthe (and use it’s websocket subscriptions). Then you can keep the React frontend.
Option 2: less javascript
Try Liveview; but know how to combine it with Javascript libs before you start building and keep in mind the roundtrip delays.
Option x, y, z…etc we need more info
