A Flask extension that forces extremely skinny controllers.

@app.route("/dogs/<int:dog_id>", methods=["POST"])
@skinny.responses({200: responses.greet_dog, 400: responses.bad_request})
@skinny.intent(intents.greet_dog)
def greet_dog(dog_id):
    pass

Description

This extension contains two decorators, @skinny.intent and @skinny.responses.

• @skinny.intent(callable)
  • callable: Receives flask.request, returns status_code and outcome.
• @skinny.responses({status_code: callable, ...})
  • callable: Receives flask.request and outcome, returns headers and body.

@skinny.responses will choose an appropriate response by status_code.

Simple Usage

from flask import Flask
from flask_skinny import skinny
from random import randint
import json


def intent(request):
    if randint(0, 1) == 0:
        status_code = 200
        outcome = "OK"
    else:
        status_code = 403
        outcome = "Forbidden"
    return status_code, outcome


def response(request, outcome):
    headers = {"content-type": "application/json"}
    body = json.dumps({"message": outcome}) + "\n"
    return headers, body


app = Flask(__name__)


@app.route("/", methods=["GET"])
@skinny.responses({200: response, 403: response})
@skinny.intent(intent)
def index():
