This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

PostgreSQL 注册登录配置

1. 将 .env.example 复制为 .env.local，并填写 DATABASE_URL。
2. 运行 npm run db:migrate。该命令由 Node.js 直接连接 PostgreSQL，不要求本机安装 psql，本地与线上环境都可使用。
3. 启动项目后访问 /account，即可注册、登录和退出。

迁移文件位于 database/migrations/。每个迁移只会执行一次，执行记录和校验值保存在数据库的 schema_migrations 表中。上线时应在发布流程中先执行 npm run db:migrate，成功后再发布应用；不要把数据库迁移放进 Vercel 的每次 Serverless 请求。

密码使用 bcrypt 强哈希保存；浏览器只保存 HttpOnly、SameSite=Lax 的随机会话令牌，数据库仅保存令牌的 SHA-256 摘要。

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.
