Local Chat System Setup Guide

為什麼要做這件事？ 在開發和測試即時通訊功能時，我發現市面上缺乏一個簡單、可本地部署的聊天系統模擬器。無論是用於面試技術展示、教學演示，還是快速原型開發，都需要一個能夠在本地環境中運行的完整聊天系統。這個 Local Chat System 的建立動機源於實際需求：我需要一個能夠展示即時通訊核心功能（用戶登入、訊息發送、跨標籤頁狀態同步）的完整範例，同時又要足夠輕量，能夠快速部署和測試。更重要的是，這個專案展示了如何使用 TypeScript 和 React 構建一個具有良好型別安全性和用戶體驗的現代化應用，這對於想要學習即時通訊開發的開發者來說，是一個極佳的實戰範例。

Environment Setup
