Introduction to Network Programming Homework

System Architecture

• The client program uses a TUI framework 'bubbletea' in Go.
• The auth server use HTTP with in-memory SQLite as backend.
• After auth, you can select the role to connect using P2P.
  • Server: listen for client to join
  • Client: scan and choose server to join

Connections

• The auth server uses HTTP RESTful API, with JSON format payload and HTTP Basic Auth.
• The UDP part uses builtin 'net' package in Go, and use MessagePack with some pre-shared Magic Number to prevent spoofing.
• The wordle server also uses HTTP RESTful API, with JSON format payload.

Gameplay

• A Wordle replica with multiplayer support.
• Players guess the 5-letter word within 6 round.
• After each round the guess result of others will be shared between players.
• The person who guess the word first wins.
