FastAPI Responses

Find HTTPExceptions and turn them into documented responses. 🎉

Installation

pip install fastapi-responses

Usage

The simplest use case happens when we have a single exception being raised. We don't want to document the possible response manually, so FastAPI Responses comes in handy.

from fastapi import FastAPI, HTTPException
from fastapi_responses import custom_openapi

app = FastAPI()

app.openapi = custom_openapi(app)

@app.get("/{item_id}")
def get_item(item_id: int):
    if item_id == 0:
        raise HTTPException(status_code=404, detail="Item not found.")
    return "Item exists!"

Without FastAPI Responses

Roadmap

• Extract HTTPException from stack.
• Extract any exception and document based on the exception_handler container.
• Accept Python objects on HTTPException instantiation.
