Setting favicon with FastAPI?

Just return a FileResponse in the GET request to /favicon.ico

File structure:

root
|-main.py
|-favicon.ico

main.py

from fastapi import FastAPI
from fastapi.responses import FileResponse

app = FastAPI()
favicon_path = 'favicon.ico'

@app.get('/favicon.ico')
async def favicon():
    return FileResponse(favicon_path)

To hide the path operation from the schema (used to make the docs), add include_in_schema=False to the decorator (credit@Tom Pohl):

@app.get('/favicon.ico', include_in_schema=False)

I had this same issue and dorked around trying different things and it only started working after I mounted folder for static files.

In main.py

from fastapi.staticfiles import StaticFiles
app = FastAPI()
app.mount("/static", StaticFiles(directory="static"), name="static")

In home.html head area

<link id="favicon" rel="icon" type="image/x-icon" href="static/images/favicon.ico">

I suspect it's related to folder permissions.
