peerchat

A terminal-based P2P chat application using libp2p and Golang that uses a Kademlia DHT and the IPFS network for peer discovery and routing. The application was inspired by chat examples found on libp2p's pubsub library, but is more evolved and fully featured version of it. It uses a Kademlia DHT from libp2p for peer discovery and routing and supports a more fully featured host. The other components of the libp2p such as TLS encryption, peer active discovery, YAMUX stream multiplexing are integrated as well. The application also allows users to jump between different chat rooms without having to restart the application and they can also change their usernames at any point. The application works for two nodes on the same network or on different networks. Nodes that are behind NATs on private network are able to communicate with each other because the application attempts to configure the router automatically using UPnP and also uses AutoRelay (TURN) to facilitate the connection.
