websocket_core library

WebSocket Core - Backend WebSocket package for Dart

A pure WebSocket backend core with explicit protocol, session management, reconnection, rooms and zero external dependencies.

Quick Start

import 'package:websocket_core/websocket_core.dart';

void main() async {
  final server = WsServer(
    config: WsServerConfig(port: 8080),
  );

  // Register event handlers
  server.on('chat.message', (context) async {
    // Broadcast to room
    server.rooms.broadcast(
      context.payload['roomId'],
      context.message,
      excludeSessionId: context.sessionId,
    );
    return null;
  });

  await server.start();
}

Core Concepts

• Session > Connection: Sessions survive connection drops
• Explicit Protocol: No implicit message formats
• Pluggable Auth: Implement your own authentication
• Rooms by Session: Rooms track sessions, not connections
