Socket.io server typescript decorators

Sio-tsc is simple typescript library to help you build applications based on socket.io.

How it works

Decorator registers class and it's methods to global singleton container.
After calling init on SioController, it will instantiate all registered classes and pass decorated methods to socket.on() callback on socket connection.

Usage

You can create multiple classes for single namespace, but keep in mind that method name is used as event name passed to socket.on.

@SioNamespace({
  name: '/', // '/' is global namespace
  middleware: [], // optional
  onConnection: [EventFetch.onConnection] // optional
})
export class TestNamespaceClass {
  static onConnection(socket) {
    socket.emit('test', {data:'test'});
  }
  
  @SioEvent()
  testEvent(data: any, socket: SocketIO.Socket) {
    setTimeout(() => {
      socket.emit('testEventResponse', data);
    }, 500);
  }
}

const sioCtrl = SioController.getInstance();
sioCtrl.init(io);

That's all, after calling init, it should work. Remember to import your files to main file or create some loader.

Installation

From npm:
npm i sio-tsc --save
