Wang Zhuoxuan b872b1cad9 feat: implement Phase 1b core features and Phase 1c commercialization
Phase 1b — Core Features:
- Huawei ID Kit login (token exchange + user info) with guest mode
- Quiz engine: randomized questions, distractor shuffling, answer verification
- XP service with combo bonuses (3/5/10-hit streaks), daily reset
- Streak service: >=3 correct/day, freeze, UTC date handling
- Hearts service: 5/day, 30min auto-restore, Pro unlimited
- 50 quiz questions across 3 categories (history/drama/crosstalk)
- 13 skill tree chapters with linear progression
- Idempotent seed import script (categories → skill tree → questions)
- 7 admin CRUD services (questions, categories, knowledge cards,
  skill tree, users, stats, feedback) with Zod validation
- All routes use Zod schema validation, /auth/me endpoint

Phase 1c — Commercialization:
- Leaderboard with live XP ranking, 10 tiers, weekly settlement
- Achievement system with 15 seed achievements and condition checking
- Huawei IAP receipt verification + subscription management
- Differentiated rate limiting (auth 10/min, quiz 60/min)
- Admin audit logging middleware

Infrastructure:
- Vitest test framework with DB mock utilities (19 tests passing)
- 12 DB tables (5 new: question_ratings, user_feedback, achievements,
  user_achievements, leaderboard_snapshots, subscriptions, admin_audit_log)
- TypeScript strict mode: zero errors

CLAUDE.md — duoqi-api

多奇服务端 API基于 Fastify + TypeScript + Drizzle ORM + MySQL 8.0+ 包管理器:bun(禁止使用 npm

项目概述

多奇Duoqi是游戏化知识闯关学习平台。duoqi-api 是三端HarmonyOS / Flutter / Web共享的后端服务从 Phase 1 起即为 HarmonyOS 客户端提供 API 支持。

技术栈

层面 选型 说明
后端框架 Fastify 5 高性能,内置 JSON Schema 验证TypeScript 友好
ORM Drizzle ORM 轻量、类型安全,src/db/schema.ts 为唯一真相源
数据库 MySQL 8.0+ 阿里云 RDS
认证 @fastify/jwt 自建 JWT华为 ID Kit + 游客模式)
校验 Zod 环境变量校验;请求体校验待迁移至 Fastify JSON Schema
运行时 Node.js (ESM) "type": "module"import 使用 .js 后缀

Quick Start

bun install                    # 安装依赖
cp .env.example .env           # 复制环境变量模板,填入实际值
bun run dev                    # 启动开发服务器,默认端口 3000

必填环境变量:DATABASE_URL, JWT_SECRET, ADMIN_TOKEN

开发命令

bun run dev          # 启动开发服务器tsx watch 热重载)
bun run typecheck    # 类型检查tsc --noEmit
bun run build        # 编译到 dist/
bun run db:push      # 推送 schema 到数据库(开发用)
bun run db:generate  # 生成迁移文件
bun run db:migrate   # 执行迁移
bun run db:seed      # 导入种子数据
bun run db:studio    # Drizzle Studio数据库可视化浏览器
bun run lint         # ESLint 检查

编码约定

  • 路由只做参数提取和响应格式化,业务逻辑在 services/
  • 响应格式统一{ success: boolean, data: T | null, error: { code, message } | null }
  • 分页响应:额外包含 pagination: { total, page, limit }
  • 不可变数据Object.freeze() 或返回新对象,不修改入参
  • 错误处理:抛出 AppError 子类(NotFoundError, ValidationError 等),由 errorHandler 统一捕获
  • 环境变量:所有配置通过 src/utils/config.ts 读取Zod 校验),禁止直接读 process.env
  • 导入后缀ESM 项目,本地导入必须带 .js 后缀(import { x } from './foo.js'

API 约定

  • Base URL: /v1
  • 认证:Authorization: Bearer <jwt>(公开端点:/v1/auth/*, /v1/health
  • Admin 认证:Authorization: Bearer <admin_token>/v1/admin/*
  • JWT 有效期access_token 1h, refresh_token 30d

数据库

  • 7 张核心表:users, categories, questions, knowledge_cards, user_progress, skill_tree, user_chapter_progress
  • Schema 定义在 src/db/schema.ts,迁移由 drizzle-kit 从 schema 自动生成
  • datetime 列使用 default(sql\CURRENT_TIMESTAMP`)MySQL datetime 无 defaultNow()`
