Integrating FastAPI with React: Serving the Built Frontend via an API Endpoint

Frontend and Backend Development
1

I need guidance serving a React build via FastAPI. For example:

from fastapi import FastAPI
from fastapi.responses import HTMLResponse

app_instance = FastAPI()

@app_instance.get("/", response_class=HTMLResponse)
def serve_home():
    with open('public_build/home.html', 'r') as f:
        return f.read()

Also, how do I handle multiple pages within one build?

hey, i think using fastapi.staticfiles could maybe your preferable route. have u tryed serving the frontend this way so that dynamic react routes work out? what are ur thoughts on managing that more efficiently?

hey try mounting the build folder with fastapi.staticfiles and use a wildcard path for unknown urls to serve index. react router can then manage its own routing. hope this helps!
