stlite does does support custom streamlit components that inject react dependencies

[intelligentestech]

For example, streamlit_code_editor. The issue is that while it seems to work at first, if the react component starts to request any additional files / bundles, the web server hosting stlite is asked to serve them, instead of the web server inside stlite.

As a specific example, below are the console errors when I load stlite from a file on my local machine https://localhost:44339/PageStreamlit_embed.html and use this simple python script:

import micropip
await micropip.install('streamlit_code_editor')

import streamlit as st
st.title("Code Editor")

from code_editor import code_editor
response_dict = code_editor("select * from tb_documents;", lang="sqlserver")

 Refused to apply style from 'https://localhost:44339/PageStreamlit_embed.html/bootstrap.min.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
