Capsule：将Web应用和数据打包到单个SQLite文件

开发者在Hacker News展示了Capsule项目，这是一款用Rust和Tauri 2.0开发的工具，能够将HTML应用及其数据封装到单个SQLite文件中1。该项目旨在创建完全自包含的Web应用，实现易于分享和部署。

Capsule提供灵活的数据存储方案，用户可选择使用localStorage键值对或MongoDB风格的文档集合来保存数据1。HTML文件和资源直接嵌入SQLite数据库，支持存储PDF、图像等多种格式的资源1。导出方面，应用允许将数据导出为CSV或JSON格式1。

在隐私和安全设计上，Capsule采取了保护措施：应用文档默认无法直接访问文件系统，需通过权限模型才能获得文件系统访问权限或连接互联网1。项目支持本地或远程AI模型集成1，每个数据条目都配备UUID和时间戳以支持版本合并1。开发者计划在1.0版本发布时开放文件格式规范，供其他应用使用1。感兴趣的用户可访问https://withcapsule.app/preview进行网页预览[1](#source-1)。

A developer has showcased Capsule on Hacker News, a new tool built with Rust and Tauri 2.0 that packages HTML applications and their data into a single SQLite file 1. The project enables developers to create self-contained web applications where HTML files, resources, and data coexist within one portable database, eliminating the need for separate file management systems.

Capsule supports multiple data storage approaches to accommodate different use cases 1. Users can store data as localStorage key-value pairs or employ a MongoDB-style document API for more complex data structures 1. The tool also allows direct storage of resources such as PDFs and images within the database itself 1. Data can be exported to CSV or JSON formats for external processing 1. Each data entry includes a UUID and timestamp to facilitate version merging 1.

Privacy and security are core design principles of the project 1. By default, applications have no direct access to the file system and cannot connect to the internet without explicit permissions 1. The tool can integrate both local and remote AI models within the application environment 1. Looking ahead, the developer plans to release the file format specification in version 1.0 to enable other applications to read and work with Capsule files 1.
