bareasgi 3.7.0

A lightweight ASGI framework

bareASGI

A lightweight Python ASGI web server framework (read the docs).

Overview

This is a bare ASGI web server framework. The goal is to provide a minimal implementation, with other facilities (serving static files, CORS, sessions, etc.) being implemented by optional packages.

The framework is targeted at micro-services which require a light footprint, or as a base for larger frameworks.

Python 3.7+ is required.

Optional Packages

• bareASGI-cors for cross origin resource sharing,
• bareASGI-static for serving static files,
• bareASGI-jinja2 for Jinja2 template rendering,
• bareASGI-graphql-next for GraphQL and grapehene,
• bareASGI-rest for REST support,
• bareASGI-prometheus for prometheus metrics,
• bareASGI-session for sessions.

Functionality

While lightweight, the framework contains all the functionality required for developing sophisticated web applications including:

• Http (1.0, 1.1, 2, 3),
• WebSockets,
• A method and path based router,
• Middleware,
• Http 2 push,
• Streaming requests and responses.

Simple Server

Here is a simple server with a request handler that returns some text.

import uvicorn
from bareasgi import Application, text_writer

async def http_request_callback(scope, info, matches, content):
    return 200, [(b'content-type', b'text/plain')], text_writer('This is not a test')

app = Application()
app.http_router.add({'GET'}, '/', http_request_callback)

uvicorn.run(app, port=9009)
