p2p-goban

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.

Screenshot

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.

Features

  • 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

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, http://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

Open index.html in a modern browser.
