浏览器存储
用途
根据数据大小、安全要求和生命周期选择合适的客户端存储方案。
流程
- 先判断数据敏感度、体积、生命周期、是否需要跨 Tab、是否需要随请求发送。
- 小量非敏感偏好用 localStorage；Tab 级临时数据用 sessionStorage；大量结构化数据或离线缓存用 IndexedDB；认证态优先 httpOnly cookie。
- 封装统一 key 前缀、JSON parse/stringify、异常处理、过期清理和 quota 兜底。
- 敏感数据按安全规则处理，不把明文 token、密码、信用卡信息放进可被 JS 读取的存储。
- 审查隐私模式、存储配额、清理策略和跨浏览器兼容性。
详细参考
涉及存储选型表、localStorage/sessionStorage 封装、IndexedDB 示例、Cookie 辅助方法和敏感数据规则时，加载 references/storage-patterns.md。
约束
- localStorage/sessionStorage 是同步 API，大数据读写会阻塞主线程。
- 除 httpOnly cookie 外，客户端存储都可被 XSS 读取。
- Cookie 每次请求自动携带，不适合大数据。
- IndexedDB 配额和隐私模式行为有浏览器差异。
- URL 中不要传 token 或敏感数据。
预期输出
产出统一的 storage/cookie/db 封装，key 有命名空间，数据有过期或清理策略，敏感数据只进入合适的安全边界。
