This project is about creating a centralized cloud-based collaborative text editor using CRDTs. For a great explanation about CRDTs, I recommend watching Martin Kleppmann's video about the subject.
The project consists of 2 separate servers:
- An HTTP server written in Golang. The code can be found in the
internalandpkgdirectories - A WebSocket server written in Rust using Axum. The code can be found in the
websocketdirectory
The HTTP server currently supports the following features:
- Logging with zerolog
- File storage in Azure Blob Storage
- Simple JWT authentication, users stored in Postgres DB
- Document creation and listing endpoint
The WebSocket server currently supports the following features:
- y-crdt document persistence in Postgres DB
- WebSocket endpoint to receive real-time updates
The client code used to connect to this server can be found at multiplayer-client
