peer_coordinator 0.3.1

Transport-neutral peer coordination: election, membership, heartbeat and synchronised data streams over a pluggable backend. Pure Dart, web-safe.

/// A chat app built on `peer_coordinator`.
///
/// Nodes join a named room through a WebSocket hub, elect a coordinator
/// between themselves, and exchange lines over the user-message channel. See
/// `lib/src/chat/chat_session.dart` for how the messages actually travel, and
/// README.md for how to run the hub.
