Hi folks ! I’m a CS student in the 6th semester at HEIG-VD.

I’ve been working on my bachelor thesis for the last weeks, and thought it might be interesting to share, since it’s a KMM project. I’ve created an online collaborative Markdown editor, using Kotlin/JS for the frontend and with a replication server in Kotlin/JVM. The editor uses some CRDTs to sync text across the clients. Messages are Protobuf-serialized with kotlinx.serialization, and sent / received through websockets with Ktor.

An interesting challenge was to design a nice abstraction layer around CRDTs with first-class support for coroutines and flows (in order, for instance, to collect editor state changes through a StateFlow).

My thesis is ending soon, but I’d love to get some feedback on my work (especially if you’re interested in CRDTs and distributed systems) and my usage of KMM, so I can integrate it in the project !

The project is available on Github : https://github.com/markdown-party/mono
