Integrate your React build with a FastAPI endpoint to avoid CORS issues. How can I serve the bundled HTML and manage multi-route setups?
from fastapi import FastAPI, HTMLResponse
app_instance = FastAPI()
@app_instance.get("/", response_class=HTMLResponse)
def display_frontend():
with open("client_build/main_page.html", "r") as file_handle:
return file_handle.read()
hey, i got around it by mounting the react folder as static files and adding a wildcard route to return index.html for unknown routes. fixed cors and multi-route issues after a few cache tunings. give it a try!
When integrating a React build with FastAPI endpoints, it is important to handle both static file serving and client-side routing carefully. In my experience, using FastAPI’s StaticFiles from Starlette to serve all assets from a designated folder helps manage multiple routes effectively. Once the static files are mounted, I define a catch-all route that returns index.html for any non-API paths, ensuring that client-side routing remains intact and CORS issues are avoided. Testing the behavior of both API and static endpoints in development and production is crucial to catch any unexpected routing problems.
hey, i tried serving my react build using fastapi static mount an a catchall route. noticed some delay in reloading. any of u found clever caching hacks or tricks? really curious to know your take on it!
hey, i used fastapi’s static mounting and a catch-all route for serving react bundles. made my multi-route setup work smoothy and fixed many cors issues. give it a try if you havent already
Integrating a React build with FastAPI can be efficient if both static file hosting and routing are managed correctly. In my previous projects, I mounted the build directory using FastAPI’s static file support and followed it with a catch-all route that returns the index.html. This approach enables client-side routing to interpret the URL while bypassing CORS challenges. It is essential to test these configurations comprehensively in production-like environments, ensuring that both asset caching and route fallbacks work seamlessly under various load conditions.
