Implement a logging module with following properties:

• Log levels should be externally controllable
• No over the top logging frameworks needed, KISS
• Separate module so that it can be used in all servers.

A Interval routine to check the health of available game servers is required to make sure the users coming to lounge and not fed with broken game server links.

Update the high scores collection after the consolidation request with a specified delay. If another consolidation request is received during the delay time then the delay is reset.

Game Server is a spaghetti with meat ball bowl: refactor and modularize. Add comments where ever necessary.

Randomize the request of leaderboard so that the consolidation server is not overwhelmed at a single point of time. This randomization also implies that emission of leaderboard via socket does not stress the game server.

The PORT environment variable should be renamed so as to relate the server it is being used for.

Use the strategy pattern to define the connection algorithm between user and game server. Existing implementation could become detrimental to swapping out websocket connection type with a more available and scalable solution.

Leaderboard data is huge compared to other data being emitted. Find out a way to compress the leaderboard data before emitting through the socket.

Create a rest path that would remove a lounge server from the collection of available game servers.

Implement an authentication system between

User<->Lounge
User<->Game Server

Can be access token based with user/pass.

The scores from a single game loop is stored in the local redis db. Once the score is sent for consolidation it is not needed by the game server. Flush the local db after the current batch of scores are sent for consolidation.

Ensure that all outgoing and incoming communication of User is encrypted.

Even though time consuming and overhead - WRITE IT!!!

For subsequent request of leaderboard generation for the same game-id serve it from in-memory cache and avoid db queries.
