aiogrpc

1.8 verified Fri May 01 auth: no python maintenance

aiogrpc provides an asyncio wrapper for gRPC (grpcio), enabling asynchronous gRPC client and server calls on Python >=3.6. The latest version is 1.8. The project appears to be in maintenance mode with no recent releases since 2020.

pip install aiogrpc

Common errors

error RuntimeError: There is no current event loop in thread 'MainThread'. ↓

cause Importing aiogrpc before an event loop is set (e.g., at module level).

fix

Import aiogrpc inside an async function or after calling asyncio.set_event_loop(asyncio.new_event_loop()).

error AttributeError: module 'grpc' has no attribute 'alpha' ↓

cause Confusion between aiogrpc and grpc.alpha (deprecated) or trying to use grpc.insecure_channel as async.

fix

Use from aiogrpc import insecure_channel.

Warnings

breaking aiogrpc requires an event loop set before importing. Importing aiogrpc without a running loop raises RuntimeError. ↓

fix Always import aiogrpc inside an async function or after asyncio.run() is called, or set a loop with asyncio.set_event_loop().

gotcha The library wraps grpc.aio only partially; streaming calls may behave differently. For example, async generators are not fully supported; use the library's own async iterators. ↓

fix Prefer using grpc.aio (official async support in grpcio >= 1.32) unless you specifically need the older aiogrpc wrapper.

deprecated The library has not been updated since 2020 and conflicts with newer grpcio versions (1.40+). ↓

fix Migrate to grpc.aio (official async gRPC). See https://grpc.io/docs/languages/python/quickstart/

Imports

insecure_channel
wrong
```
from grpc import insecure_channel
```
correct
```
from aiogrpc import insecure_channel
```
grpc.insecure_channel returns a sync channel, not async

channel_ready_future

from aiogrpc import channel_ready_future

Quickstart

Basic usage: create an insecure async channel and close it.

import asyncio
from aiogrpc import insecure_channel

async def main():
    channel = insecure_channel('localhost:50051')
    # Use channel with generated stubs, e.g., stub = GreeterStub(channel)
    await channel.close()

asyncio.run(main())
