Join game functionality

[Albin-Rohde]

Intro

When a game is crated by a user, it should be possible for other users to join the game. This should be handled by a websocket connection, as the game will be dependent on realtime data.

The first milestone should be to open a socket connection when a game is created, and allow other users to join that session. The connection should make sure to update all clients connected to game; that a new player has joined the game.

Story

As a user i want people to be able to join my game, in addition i want to see when a new player has joined. I do not want my browser to poll the backend for new data, as that could "feel" slow and laggy.

I want my game to be secure, and i don't want people who i did not invite; being able to see any data about my game.

Value

Users can join other users game, which will make it possible to start a game together.
Using websockets for this will make it very snappy and responsive.
We will establish a specific "socket-session" for a specific game. All players linked to a game will sort of subscribe to updates to the game.

• User can create a game
