nio is a multilayered Matrix client library. The underlying base layer doesn't do any network IO on its own, but on top of that is a full-fledged batteries-included asyncio layer using aiohttp. File IO is only done if you enable end-to-end encryption (E2EE).

The full API documentation for nio can be found at https://matrix-nio.readthedocs.io

nio has most of the features you'd expect in a Matrix library, but it's still a work in progress.

• ✅ transparent end-to-end encryption (EE2E)
• ✅ encrypted file uploads & downloads
• ✅ space parents/children
• ✅ manual and emoji verification
• ✅ custom authentication types
• ✅ threading support
• ✅ well-integrated type system
• ✅ knocking, kick, ban and unban
• ✅ typing notifications
• ✅ message redaction
• ✅ token based login
• ✅ user registration
• ✅ read receipts
• ✅ live syncing
• ✅ m.reactions
• ✅ m.tags
• ❌ cross-signing support
• ❌ server-side key backups (room key backup, "Secure Backup")
• ❌ user deactivation (#112)
• ❌ in-room emoji verification

To install nio, simply use pip:

$ pip install matrix-nio

Note that this installs nio without end-to-end encryption support. For e2ee support, python-olm is needed which requires the libolm C library (version 3.x). On Debian and Ubuntu one can use apt-get to install package libolm-dev. On Fedora one can use dnf to install package libolm-devel. On MacOS one can use brew to install package libolm. Make sure version 3 is installed.

After libolm has been installed, the e2ee enabled version of nio can be installed using pip:

$ pip install matrix-nio[e2e]

Additionally, a docker image with the e2ee enabled version of nio is provided in the docker/ directory.
