async-extensions

What it is and what it does

async-extensions is a utility library that extends anyio to streamline asynchronous programming in Python. It provides additional abstractions and helpers to reduce boilerplate when writing async code that needs to work across different async backends. The package depends on a small set of runtime libraries including attrs, anyio, sniffio, typing-extensions, and several internal utilities (solus, funcs, wraps, named, typing-aliases) that support its functionality.

The package is marked production-stable and supports Python 3.8 through 3.12. However, maintenance is dormant—the last release was 843 days ago and there have been no recent commits. While the repository remains unarchived and carries no known security vulnerabilities, the lack of active development means bug fixes or feature additions are unlikely without community contribution.

Use it for:

• Build async applications that need to support multiple event loop backends without rewriting code for each one.
• Reduce boilerplate when writing async utilities and helpers on top of anyio's abstractions.
• Integrate async-extensions into existing anyio-based projects to access additional async patterns or utilities.
• Develop backend-agnostic async libraries that depend on a stable, typed async foundation.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides utilities and abstractions built on anyio to simplify backend-agnostic asynchronous programming in Python.

Yes, if you are already using anyio and need additional async utilities. The package is stable, has no known vulnerabilities, and installs easily. However, be aware that maintenance is dormant—no updates or bug fixes are expected unless you or the community contribute. Install it only if its specific utilities solve a real problem in your codebase; otherwise, consider whether anyio alone meets your needs.

Installing async-extensions

Before you install

Low install friction with a pure-Python wheel. Maintenance is dormant—last release was 843 days ago and the repository shows minimal recent activity, though it remains unarchived and marked production-stable.

License in practice

MIT license is permissive; you may use, modify, and distribute this package freely in commercial and private projects with minimal restrictions.

Quickstart

pip install async-extensions

import async_extensions
# Use async-extensions utilities built on anyio for backend-agnostic async code

Requires Python 3.8 or above.

Verify before relying

• What specific async utilities or abstractions does the package provide beyond anyio's core API.
• Whether the dormant maintenance status indicates the package is feature-complete or at risk of bitrot.
• Real-world use cases or adoption patterns beyond the generic 'async extensions' framing.
