Connect to multiple peers and play/analyze on a shared Goban. This is a proof of concept and I hope that all functionalities will eventually be integrated into Sabaki. Try it out here.

First, you connect to a server to see who's there. Then, peers share the game tree with each other peer-to-peer. There's no centralized server that saves your game. We use WebRTC, so all communication between peers are encrypted.

• Connect to other people peer-to-peer
• Play a game or analyze games together in real time
• Chat with other peers
• Upload SGF files
• Download game as an SGF file
• Follow a peer to see what they see
• Right-click to highlight vertices to signal peers what you're looking at

Building requires Node.js and npm. First, clone this repository and install all the dependencies:

$ git clone https://github.com/yishn/p2p-goban
$ cd p2p-goban
$ npm install

Start a signalhub server with npx:

$ npx signalhub listen -p 51624

Open config.example.json, add the URL to your signalhub server, https://localhost:51624 in this example, and save it under config.json.

For development, use the following command to create a bundle automatically while you edit files:

$ npm run watch

For production, use the following command instead:

$ npm run build
