python - How to generate multiple Dash App (and URLs) programmatically?

Question

I have a simple Dash app with a choropleth map along with a simple dropdown. The data is sourced from a pandas dataframe and contains a few different metrics for each US state.

I'd like to reproduce this standard layout for each of the US state but here's the problem:

1. I'd like to avoid having to create 50 different dash apps (it doesn't look really practical neither scalable)
2. I don't want to have a dropdown for users to select the state: the goal is to have multiple URLs, one for each state (mostly for search engine purposes).

I was thinking of passing the US state as a URL parameter: I'd use this variable to filter the dataframe (limiting the dataframe scope will automatically make the choropleth zoom to the relevant state). However this is problematic since:

1. Dash doesn't allow to set a default base URL for the app (at least as far as I could tell)
2. The df cleaning/filtering happens before I can call the flask instance in Dash (this would be easily solvable though) as well as the app URL.

I wanted to do this all within Dash for practicality but I guess I'd need to rely on Flask/Django for the actual scaffolding and pull in Dash content from there?
