Joseph POURADIER DUTEIL

• Front end
• Nodejs socket

Elements réalisés

• Mise en place d'une interface pour jouer et le chat
• Mise en place du match making
• Sauvegarde des logs sur le broker
• mise en place du proxy

Elements non réalisés

• Pendant le jeu, il n'y a pas d'energie pour jouer

Roadmap

J'ai envie de tester la difference de performance entre le monolitique en java et en Go. Pour cela on utilisera gatling pour simuler des utilisateurs/du traffic. Et on visualisera les performances de chaque solution dans Grafana/Prometheus.

Github CI

STOMP

I got a lot of truble with the stomp protocol:
With the js librart stompit I got no issue passing the message to the broker and read it in java. The TextMessage is well received.
But when i send a message with the go package go-stomp, it is parsed a BytesMessage.

I tried to change the content-type of the message, but it didn't change anything.

So I made some research about the stomp and JMS protocol. And compared the frames created by the two libraries: With stompit:

Command: MESSAGE
Headers: {
  expires: '0',
  destination: '/queue/test',
  subscription: '1',
  priority: '4',
  'message-id': 'ID:f61b9fbb07ad-41815-1735584783348-3:34:-1:1:1',
  'content-type': 'text/plain',
  timestamp: '1735764298315'
}
Body: Hello, STOMP!

With go-stomp:

Command: MESSAGE
Headers: {
  'content-length': 13,
  expires: '0',
  destination: '/queue/test',
  subscription: '1',
  priority: '4',
  'message-id': 'ID:f61b9fbb07ad-41815-1735584783348-3:35:-1:1:1',
  'content-type': 'text/plain',
  timestamp: '1735764310899'
}
Body: Hello, STOMP!

The only noticable difference is the content-length header. So I forked the project and deleted the line that add the content-length header.
