Examples

Basic usage

project/main.py

from backendpy import Backendpy
from backendpy.response import Text

application = Backendpy()

@application.uri(r'^/hello-world$', ['GET'])
async def hello(request):
    return Text('Hello, World!')

$ uvicorn main:application

Backendpy app based usage

Example app:

hello_app/main.py

from backendpy.app import App
from .handlers import routes

app = App(
    routes=[routes])

hello_app/handlers.py

from backendpy.router import Routes
from backendpy.response import Text

routes = Routes()

@routes.uri(r'^/hello-world$', ['GET'])
async def hello(request):
    return Text('Hello World!')

Example project:

project/main.py

from backendpy import Backendpy

application = Backendpy()

project/config.ini

[apps]
active =
    app_python_path.hello_app

Run project with uvicorn main:application
