Use web socket along Http request

[guilherme-diniz]

Hi,

Is there a way to setup WebSocket listeners along with http requests?

import 'dart:async';

import 'package:functions_framework/functions_framework.dart';
import 'package:shelf/shelf.dart';
import 'package:shelf_router/shelf_router.dart';
import 'package:shelf_web_socket/shelf_web_socket.dart';

/// ./server.exe
@CloudFunction()
FutureOr<Response> function(Request request) async {
  final app = Router();

  app.get('/', (Request request) {
    return Response.ok('root');
  });

  return app(request);
}

@CloudFunction()
FutureOr<Response> webSocket(Request request) async {
  var app = Router();

  var wsHandle = webSocketHandler((webSocket) {
    webSocket.stream.listen((message) {
      print(message);
      webSocket.sink.add('echo $message');
    });
  });

  app.get('/', wsHandle);

  return app(request);
}

./bin/server.exe --target=webSocket
