後端開發模式

用於可擴展伺服器端應用程式的後端架構模式和最佳實務。

API 設計模式

RESTful API 結構

// PASS: 基於資源的 URL
GET    /api/markets                 # 列出資源
GET    /api/markets/:id             # 取得單一資源
POST   /api/markets                 # 建立資源
PUT    /api/markets/:id             # 替換資源
PATCH  /api/markets/:id             # 更新資源
DELETE /api/markets/:id             # 刪除資源

// PASS: 用於過濾、排序、分頁的查詢參數
GET /api/markets?status=active&sort=volume&limit=20&offset=0

Repository 模式

// 抽象資料存取邏輯
interface MarketRepository {
  findAll(filters?: MarketFilters): Promise<Market[]>
  findById(id: string): Promise<Market | null>
  create(data: CreateMarketDto): Promise<Market>
  update(id: string, data: UpdateMarketDto): Promise<Market>
  delete(id: string): Promise<void>
}

class SupabaseMarketRepository implements MarketRepository {
  async findAll(filters?: MarketFilters): Promise<Market[]> {
    let query = supabase.from('markets').select('*')

    if (filters?.status) {
      query = query.eq('status', filters.status)
    }

    if (filters?.limit) {
      query = query.limit(filters.limit)
    }

    const { data, error } = await query

    if (error) throw new Error(error.message)…
