## What it is
asgiref is the reference library for the ASGI (Asynchronous Server Gateway Interface) specification, providing base utilities for Python async web apps and servers. It includes sync-to-async and async-to-sync function wrappers, a WSGI-to-ASGI adapter, server base classes, and a thread/task-aware threadlocal replacement.

## Use cases
- call async functions from synchronous code in python
- run sync django views inside an asgi server
- adapt a wsgi app to run on an asgi server
- write a stateless async server that consumes external sockets
- share thread-local state across asyncio tasks and threadpools
- bridge sync and async code during a gradual asyncio migration

## When to avoid
- you need a full web framework or production ASGI server rather than base utilities
- your project is purely synchronous with no asyncio involvement
- you need HTTP routing, templating, or ORM features - asgiref provides none

## Facets
- artifact type: library
- maturity: stable
- function: middleware, http-server, concurrency
- domain: web-development, backend, developer-tools
- platform: python, cross-platform
- tags: asgi, asyncio, wsgi, sync-async-bridging, web-servers
