Fastify vs Express 效能對比:
根據官方 Fastify 文件和社群測試,Fastify 相較於 Express 有顯著的效能優勢:
這也是我們選擇 Fastify 作為後端框架的主要原因。
API 效能特性:
基於 Fastify 和 oRPC 架構,我們的 API 具備以下特性:
/api/otp/send
): 需呼叫外部 SMS API,回應時間取決於 Mitake 服務/api/otp/verify
): 純 Redis 查詢,回應快速 (< 50ms)/api/templates
): 快取優化,低延遲/api/auth/*
): JWT 驗證,使用 JOSE 庫/api/members
, /api/tenants
): 多租戶架構,動態資料庫連線目前處於開發階段,尚未進行大規模壓力測試。主要關注:
目前系統採用多租戶架構,使用動態資料庫連線:
// packages/kyo-core/src/database/tenant-service.ts
// 動態租戶資料庫連線管理
主要特性:
- 每個租戶 (gym) 獨立的資料庫連線
- 連線池管理,避免資源浪費
- 支援跨租戶查詢 (需要時)
- 租戶隔離,確保資料安全
資料庫設計考量:
目前使用 Node.js 內建測試執行器 (node --test
):
// package.json
{
"scripts": {
"test": "node --test",
"pretest": "tsc -p tsconfig.json" // 先編譯 TypeScript
}
}
測試重點:
尚未建立完整的測試覆蓋率,主要依靠:
// 1. JWT 認證 (使用 JOSE 庫)
