Or use the following command to install optional additional libraries:

$ pip3 install backendpy[full]

You also need to install an ASGI server such as Uvicorn, Hypercorn or Daphne:

$ pip3 install uvicorn

Create Project

project/main.py

from backendpy import Backendpy

bp = Backendpy()

Create Application

project/apps/hello/main.py

from backendpy.app import App
from .handlers import routes

app = App(
    routes=[routes])

project/apps/hello/handlers.py

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

routes = Routes()

@routes.get('/hello-world')
async def hello(request):
    return Text('Hello World!')

Activate Application

project/config.ini

[networking]
allowed_hosts =
    127.0.0.1:8000

[apps]
active =
    project.apps.hello

Run Project

Inside the project root path:

$ uvicorn main:bp

Command line

The basic structure of a project mentioned above can also be created by commands:

$ backendpy create_project --name myproject

To create a project with more complete sample components:

$ backendpy create_project --name myproject --full

Or to create an application:

$ backendpy create_app --name myapp

$ backendpy create_app --name myapp --full
