ZeroMQ integration with asyncio (PEP 3156).


Library Installation

The core requires only pyzmq and can be installed (with pyzmq as dependency) by:

pip3 install aiozmq

Also probably you want to use aiozmq.rpc.

RPC module is optional and requires msgpack. You can install msgpack-python by:

pip3 install msgpack-python


aiozmq can be executed by Python 3 only. The most Linux distributions uses pip3 for installing Python 3 libraries but maybe your system uses Python 3 by default. Than try just pip instead of pip3. The same issue may be for virtualenv, travis continuous integration system etc.

Source code

The project is hosted on GitHub

Please feel free to file an issue on bug tracker if you had found a bug or have some suggestion for library improvement.

The library uses Travis for Continious Integration.


Authors and License

The aiozmq package is initially written by Nikolay Kim, now maintained by Andrew Svetlov. It’s BSD licensed and freely available. Feel free to improve this package and send a pull request to GitHub.

Getting Started

At first you need to install aiozmq policy to use ZeroMQ socket layer:

import asyncio
import aiozmq


For details please take a look on Installing ZeroMQ event loop.

After that you probably would like to use RPC:

import aiozmq.rpc

class ServerHandler(aiozmq.rpc.AttrHandler):
    def remote_func(self, a:int, b:int) -> int:
        return a + b

def go():
    server = yield from aiozmq.rpc.serve_rpc(
        ServerHandler(), bind='tcp://')
    client = yield from aiozmq.rpc.connect_rpc(

    ret = yield from client.rpc.remote_func(1, 2)
    assert 3 == ret




To execute the example you need to install msgpack first.
