bareasgi 4.2.0

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 (in a container for example), or as a base for larger frameworks.

Python 3.8+ 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 graphene,
• bareASGI-rest for REST support,
• bareASGI-prometheus for prometheus metrics,
• bareASGI-session for sessions.

Functionality

The framework provides the basic functionality required for developing a web application, including:

• Http,
• WebSockets,
• Routing,
• Lifecycle,
• Middleware

Simple Server

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

import uvicorn
from bareasgi import Application, HttpRequest, HttpResponse, text_writer

async def example_handler(request: HttpRequest) -> HttpResponse:
    return HttpResponse(
        200,
        [(b'content-type', b'text/plain')],
        text_writer('This is not a test')
    )

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

uvicorn.run(app, port=9009)
