# 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.
