@n0iroh at https://iroh.computer may be an interesting #p2p case study for you. #iroh is in turn used by @delta for instance.
You can read more on how #DeltaChat use iroh in their blog post at: https://delta.chat/en/2024-11-20-webxdc-realtime
Iroh's programming language used is #Rust though, but via the #WebAssembly support it may be usable in the languages you mention, but I am not sure.
Starting work on #kikai networking using #iroh as a messaging backend.
The idea is to keep it as simple as possible, sync ticks. Only the units position and hp is synced. Clients can subscribe to full syncs of #Uxn state for some units (like selected ones) in order for debugging and custom unit UIs to work well.
Ever used #sendme to send files around using #iroh? It is built on top of the iroh-blobs protocol, which uses blake3 to do verified streaming. If you do this at scale you also want a store for the blobs, and that's not so trivial to build: https://www.iroh.computer/blog/blob-store-design-challenges
@Junicast @kubikpixel Yes, building magic wormhole with iroh direct connections would be cool! Currently magic wormhole traffic is all relayed via a server AFAIK.
Iroh is open source, and you can self-host a relay. And iroh runs on mobiles. E.g. @delta does all of those things and integrates an #iroh relay in their #ChatMail server. And #DeltaChat runs on mobiles.
The coolest part is that it has a LAN working over #iroh real-time channels. Everyone can assign self an IP address and ping each other, telnet etc.
with e2e encrypted forward secrecy connection between machines! 
Currently playing around with https://github.com/MightyShadow702/v86Emu-webxdc which leverages https://github.com/copy/v86 into DeltaChat. Effectively allowing you to run a 32 bit .iso file inside DeltaChat as a webxdc application.
Right now tcp/ip is wired up with realtime communication over iroh 
Our #iroh relay servers are so blind to the traffic that they don't even know when #p2p #holepunching has succeeded for two nodes. Yet people keep asking what our hole punching rate is.
Honestly, we don't know! And we don't know how to find out without violating everyone's privacy. How to square this circle?
Some users of private centralised deployments tell us it is better than anything else they tried, hence they switched. But we don't have numbers, and who believes a claim like that?
New video! Build #sendme into you app:

#filesharing with #iroh, #p2p
#Iroh is a super fascinating project in the #LocalFirst ecosystem. You always have incredible progress in roadmap briefings, and a very good codebase + docs to get folks going.
Local-first is a next-gen computing paradigm.. one of paradigms that threaten cloud and browser vendor hegemonies.
One thing is problematic in local-fist land. There are N pioneers and N sync mechanisms / protocols.
Until there's any form of common open standards track things remain too risky technology bets.
Our friends at @delta are continuing to make #WebXDC an amazing platform: https://delta.chat/en/2025-01-23-webxdc-notifications
The realtime #WebXDC APIs are built on top of #iroh #p2p connections in #DeltaChat. Glad to be playing a part in this!
Want to start Monday morning by watching an in-depth video of how #iroh works? @bfive has you covered.

We found that in practice our support for go is just far too cumbersome. Go doesn't take well to CGO dependencies to begin with, and integrating such a thing at the networking layer just isn't worth it.
Go projects that want to interact with iroh should consider standing up a separate binary & communicating over a network-backed RPC protocol of their own design.
It's been a bit of a journey learning #rust and #veilid and #iroh but these last few functions were very satisfying to write. This code triggers a download of an Iroh-blobs based file from it's hash by establishing tunnels to peers in a group using a multiplexer I built using Veilid AppMessages over private routes. The code to get here was hella messy but these functions felt pretty elegant.
For the last several months I've been working on making a federated app.
I just finished migrating it to use the latest iteration of our new #leafprotocol data format on top of the #willowprotocol and so far it's going really well.
In this post I share some of the concepts and rational behind the Leaf Protocol:

If you wonder what iroh is. #deltachat uses it for second device setup and soon also for realtime #p2p connections in #webxdc
in calmness
