快速开始
1. 环境要求
- Node.js >= 18
- PostgreSQL 15+
- Redis 7+
2. 安装依赖
npm install
3. 配置环境变量
复制.env.example到.env并配置：
cp .env.example .env
4. 初始化数据库
# 生成Prisma Client
npm run prisma:generate
# 执行数据库迁移
npm run prisma:migrate
# （可选）打开Prisma Studio查看数据
npm run prisma:studio
5. 启动开发服务器
npm run dev
服务器将在 http://localhost:3001 启动
6. 验证服务
访问以下端点验证服务是否正常：
- 健康检查: http://localhost:3001/health
- API入口: http://localhost:3001/api/v1
