Sans-IO Implementation of WAMP

[om26er]

I have been leading an open-source effort that is inspired by https://sans-io.readthedocs.io/ and mainly based on principles followed by https://github.com/python-hyper/wsproto but for the WAMP protocol implementations. I call it the Xconn project.

At its core is a bunch of sans-io implementations of the WAMP protocol in different programming languages (and more on the way)
https://github.com/xconnio/wampproto-python
https://github.com/xconnio/wampproto-dart
https://github.com/xconnio/wampproto-ts
https://github.com/xconnio/wampproto-go
https://github.com/xconnio/wampproto-ruby

These implementations are intended to be reusable for any future WAMP client implementations. They are pluggable i.e. writing a new authenticator OR a new serializer is super simple as everything is an interface. The proof of pluggability is that I am able to write an experimental protobuf based WAMP message serializer without making changes in the library implementations https://github.com/xconnio/wampproto-protobuf

Then there are a bunch of WAMP client libraries that use the above sans-io implementations to create clients and routers
https://github.com/xconnio/xconn-dart
https://github.com/xconnio/xconn-python
https://github.com/xconnio/xconn-go
https://github.com/xconnio/xconn-ruby

The project contains tools as well
https://github.com/xconnio/wampproto-cli => is a cli tool to do interoperability testing of different sans-io implementations

https://github.com/xconnio/wick-ui => A desktop, mobile and webapp written in Flutter for WAMP API testing (Postman for WAMP).

We are lagging in documentation and that is going to be a priority for us going forward.

DISCLAIMER: This stuff is alpha quality and is not ready for production yet. I am personally funding the development.

This is absolutly sick 🤩 nice job so far! Feel free to take as much from my dart code as you want to implement features to your dart project.

Thanks. We did get help from connectanum during the development of this project. btw xconn-dart is also a router implementation. We wanted to use WAMP to inter-connect mobile devices (iOS/Android) and computers (Windows/macOS/Linux) to do cross-platform communication

awesome!

fwiw, Autobahn was designed similarly, that is sans-io + interfaces. besides serializer and authenticator, it also factors transports:

https://github.com/crossbario/autobahn-python/blob/f38f16ba28fa253dee951068cc729089c88d857d/autobahn/wamp/interfaces.py#L39

does xonnio also support different WAMP transports, if not, is it planned?

The proof of pluggability is that I am able to write an experimental protobuf based WAMP message serializer

great approach!

just one Q: curious, why protobuf when there is flatbuffers binding for WAMP already? eg

https://github.com/crossbario/autobahn-python/blob/master/autobahn/wamp/flatbuffers/pubsub.fbs

fantastic!

this is awesome!! thank you so much for contributing to the WAMP ecosystem=)

in case this isn't obvious, I am ++1 on this - including listing of course on the WAMP website under the respective implementations lists.
