Api documentation using own external yaml or Json file.

[rohit151990]

Hi Friends,

I created my own swagger file and that I want to give for my api definition. I tried with given approach "app = FastAPI(openapi_url="/openapi.json")" but it is not loading my generated json file.

Please suggest what should I do so that I can use my own created swagger file in fastapi.

Regards,

Thanks Guys I got the solution.
this is how I can do this.

from fastapi import FastAPI
import json

app = FastAPI()

def custom_openapi():
with open("openapi.json", "r") as openapi:
return json.load(openapi)

app.openapi = custom_openapi
