RouteFactory

Class to generate routes for http methods and paths from a flask app or blueprint.

from flask import Blueprint, Flask
import flask_wrappers as wrappers

# create a flask app
app = Flask(__name__)
# or create a blueprint
## app = Blueprint("blueprint_name", __name__)

# create a route_factory from the app
route_factory = wrappers.RouteFactory(app)

options(route, **options)

Create an endpoint for the route and method OPTIONS

@route_factory.options("/names")
def my_endpoint():
    # logic here

get(route, **options)

Create an endpoint for the route and method GET

@route_factory.get("/names")

def my_endpoint():
    return ["Anna", "Alice", "Shila"], 200

post(route, **options)

@route_factory.post("/names")
@wrappers.json_request

    return "ok", 200

put(route, **options)

Create an endpoint for the route and method PUT

@route_factory.put("/names")
@wrappers.json_request

delete(route, **options)
