AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Provides a signal/callback system for asyncio applications, allowing you to register and invoke asynchronous callbacks in a managed, freezable list.

Minimal friction: pure Python wheel with only two lightweight runtime dependencies (frozenlist and typing-extensions), active maintenance with a recent release in July 2025.

Apache 2.0 permissive license allows commercial and private use with minimal restrictions; you must retain license notices in distributions.

pip install aiosignal

import asyncio
from aiosignal import Signal

async def callback(data):
    print(f"Received: {data}")

async def main():
    sig = Signal()
    sig.append(callback)
    sig.freeze()
    await sig.send("hello")

asyncio.run(main())

Verdict: A stable, well-maintained asyncio signal library with no known vulnerabilities, low install friction, and permissive licensing. Suitable for projects needing managed callback dispatch in async contexts.

Needs verification

• Whether the package is actively used in production systems beyond the aio-libs ecosystem.
• Performance characteristics under high callback volume or concurrent signal sends.
