Capsule:把网页应用和数据打包进单个 SQLite 文件
作者在 Hacker News 发布 Capsule,一个用 Rust 和 Tauri 2.0 编写的应用,可将 HTML 应用及其数据打包成单个 SQLite 文件(文件扩展名也是 Capsule)。HTML 与相关资源直接嵌入数据库;用户数据可存为 localStorage 键值或通过类 MongoDB 的 collections API 以文档形式存入表中,PDF、图片等资源也可一并保存,并支持导出 CSV 或 JSON。文档默认无文件系统访问权限,联网需授权,权限模型仍在改进;还可调用本地或远程 AI 模型。多人协作会产生不同副本,因此每条数据带 UUID 和时间戳以便合并。作者计划在 1.0 版本开放文件格式规范,并已提供网页预览和 AI 提示词。
为什么值得看单文件 SQLite 打包网页应用与数据,权限模型和 AI 集成思路清晰,适合做本地优先、可分享的轻量产品原型。
