flask-typed

A Flask extension for developing HTTP APIs using type annotations. Type annotations are used for the validation of requests and generating API documentation.

Example

from flask import Flask
from pydantic import BaseModel

from flask_typed import TypedResource, TypedAPI


class HelloResponse(BaseModel):

    message: str
    sender: str
    receiver: str


class HelloResource(TypedResource):

    def get(self, sender: str, receiver: str) -> HelloResponse:
        """
        Greets someone

        :param sender: Greeter
        :param receiver: The one being greeted
        :return: Greetings
        """
        return HelloResponse(
            message=f"Hello to {receiver} from {sender}!",
            sender=sender,
            receiver=receiver
        )


app = Flask(__name__)
api = TypedAPI(app, version="1.0", description="Greetings API")

api.add_resource(HelloResource, "/hello/<sender>")

if __name__ == "__main__":
    app.run()
