DefEssential

The Modern Synchronous Python Web Application Framework

DefEssential is a synchronous Python web framework for handling HTTP requests with ordinary methods. Python 3.9 or later is required.

Installation

python -m pip install DefEssential

The built-in Python HTTP server requires no additional server dependency. Optional extras provide Gunicorn and Uvicorn adapters:

python -m pip install "DefEssential[Gunicorn]"
python -m pip install "DefEssential[Uvicorn]"

Quick start

Save this example as app.py and run python app.py.

from DefEssential import Application, Request, RequestRunner
from DefEssential.Adapter.Implements.Python import Server
from DefEssential.Responses import ResponseText


class Hello(RequestRunner, method='GET', url='/hello'):
  def run(self, request: Request):
    return ResponseText('Hello, world!')


application = Application()
application.add(Hello)
Server('127.0.0.1', 8000, application).run()

The server listens on 127.0.0.1:8000. A GET /hello request returns Hello, world!.
