Build Status codecov PyPI PyPI - Downloads

Python client for NATS messaging system.

This project is a replacement for abandoned pynats. nats-python supports only Python 3.6+ and fully covered with typings.

Go to the asyncio-nats project, if you're looking for asyncio implementation.


$ pip install nats-python


from pynats import NATSClient

with NATSClient() as client:
    client.publish("test-subject", payload=b"test-payload")


To work on the nats-python codebase, you'll want to clone the project locally and install the required dependencies via poetry:

$ git clone
$ make install

To run tests and linters use command below:

$ make lint && make test

If you want to run only tests or linters you can explicitly specify which test environment you want to run, e.g.:

$ make lint-black


nats-python is licensed under the MIT license. See the license file for details.
