# Cline's Memory Bank
|
||||||
|
|
||||||
|
I am Cline, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.
|
||||||
|
|
||||||
|
## Memory Bank Structure
|
||||||
|
|
||||||
|
The Memory Bank consists of core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:
|
||||||
|
|
||||||
|

|
||||||
|
PB[projectbrief.md] --> PC[productContext.md]

|
- Complex feature documentation
|
||||||
|
- Integration specifications
|
||||||
|
- API documentation
|
||||||
|

## Documentation Updates
|
||||||
|
|
||||||
|
Memory Bank updates occur when:
|
||||||
|
1. Discovering new project patterns
|
||||||
|
2. After implementing significant changes
|
||||||
|
3. When user requests with **update memory bank** (MUST review ALL files)
|
||||||
|
4. When context needs clarification

||||||

|
end
|
||||||
|
|
||||||
|
Start --> Process
|
||||||
|
|
||||||
|
Note: When triggered by **update memory bank**, I MUST review every memory bank file, even if some don't require updates. Focus particularly on activeContext.md and progress.md as they track current state.
|
||||||
|
|
||||||
|
REMEMBER: After every memory reset, I begin completely fresh. The Memory Bank is my only link to previous work. It must be maintained with precision and clarity, as my effectiveness depends entirely on its accuracy.

# 条码扫描器 PWA (人机协作项目)
|
||||||
|
|
||||||
|
这是一个作者为了练习与 AI 协作，而使用 AI 编写的渐进式 Web 应用 (PWA)。
|
||||||
|
|
||||||
|
在本项目中，作者负责提出需求、进行决策和提供指导，而 AI 助手 **Cline** 则根据指令完成具体的编码和文档撰写工作。这个项目旨在探索一种高效的人机协作模式。
|
||||||
|
|
||||||
|
## 项目简介
|
||||||
|
|
||||||
|
本项目是一个功能完整的条码扫描应用，旨在提供快速、便捷的条码扫描和管理体验，无需安装原生应用。它包含两个核心功能模块：
|
||||||
|
|
||||||
|
1. **实时扫描**: 通过设备摄像头实时捕捉和解析条码。
|
||||||
|
2. **历史记录**: 保存、查看、管理和导出扫描过的条码。
|
||||||
|
|
||||||
|
## 功能特性
|
||||||
|
|
||||||
|
- **实时扫描**:
|
||||||
|
- 动态申请摄像头权限并渲染视频流。
|
||||||
|
- 支持从多个摄像头中选择。
|
||||||
|
- 使用 Quagga2 实时检测视频流中的条码。
|
||||||
|
- 在画面上高亮显示识别到的条码。
|
||||||
|
- 一键保存扫描结果到本地。
|
||||||
|
- **历史记录管理**:
|
||||||
|
- 使用 IndexedDB 在浏览器端持久化存储数据。
|
||||||
|
- 为每条记录添加自定义标签。
|
||||||
|
- 支持按标签筛选记录。
|
||||||
|
- 支持批量选择、删除和导出 (CSV 格式) 记录。
|
||||||
|
- **简洁的 UI**:
|
||||||
|
- 双标签页设计，通过底部导航栏轻松切换。
|
||||||
|
- 响应式布局，在桌面和移动设备上均有良好体验。
|
||||||
|
|
||||||
|

||||||
|
- **框架**: React
|
||||||
|
- **构建工具**: Vite
|
||||||
|
- **样式**: TailwindCSS
|
||||||

# 当前背景
|
||||||
|
|
||||||
|
## 当前工作重点
|
||||||
|
在核心功能完成后，本次工作重点是根据用户反馈优化 `LiveScannerPage` 的用户体验和稳定性。
|
||||||
|
|
||||||
|
## 已完成的步骤
|
||||||
|
1. **项目初始化:**
|
||||||
|
- 已使用 pnpm 和 Vite 完成项目设置。
|
||||||
|
- 所有核心依赖项均已安装和配置。
|
||||||
|
2. **页面结构与 UI 框架:**
|
||||||
|
- `LiveScannerPage` 和 `HistoryPage` 已创建。
|
||||||
|
- `BottomNav` 组件已实现，并能正常导航。
|
||||||
|
- `react-router-dom` 已配置为嵌套路由。
|
||||||
|
3. **实时扫描功能 (核心):**
|
||||||
|
- 已实现摄像头权限申请和视频流渲染。
|
||||||
|
- 已集成 Quagga2 进行条码检测和视觉反馈。
|
||||||
|
- 已实现保存最新扫描结果到数据库的功能。
|
||||||
|
4. **实时扫描功能 (优化):**
|
||||||
|
- **摄像头选择:** 添加了摄像头下拉列表，启动时不再自动扫描。
|
||||||
|
- **视频流修复:** 解决了视频流渲染黑屏的问题。
|
||||||
|
- **UI 简化:** 选择摄像头后，下拉菜单变为固定的文本标签，简化了交互。
|
||||||
|
- **结果管理:** 添加了“清空”按钮，用于清除缓存的扫描结果。
|
||||||
|
5. **历史记录功能:**
|
||||||
|
- 已使用 `idb` 设置 IndexedDB。
|
||||||
|
- 已实现记录的添加、查询和删除功能，并在页面上展示。
|
||||||
|
|
||||||
|
## 后续步骤
|
||||||
|
- **所有核心和高级功能均已完成。**
|
||||||
|
|
||||||
|
## 当前的决策和考虑
|
||||||
|
- **稳定性优先:** 为了解决设备兼容性问题，主动简化了摄像头切换逻辑，采用刷新页面重新选择的策略，以确保应用的稳定性。
|
||||||
|
- **代码结构:** 当前的代码结构（`pages`, `components`, `db`）运行良好。
|
||||||
|
- **功能完整性:** 项目已满足 `projectbrief.md` 中定义的所有核心和高级需求。

# 产品背景
|
||||||
|
|
||||||
|
## 问题陈述
|
||||||
|
需要一种快速、基于网络的方式来扫描和管理条形码，而无需安装原生应用程序。这对于库存管理、个人物品追踪、价格查询或任何需要快速识别和记录产品信息的场景非常有用。
|
||||||
|
|
||||||
|
## 用户体验目标
|
||||||
|
- **简洁性与直观性:** 界面应分为两个明确的标签页：“实时扫描”和“历史记录”。用户可以轻松理解每个页面的功能。
|
||||||
|
- **易用性:**
|
||||||
|
- 用户应能通过底部的导航按钮轻松切换页面。
|
||||||
|
- 在扫描页面，摄像头应自动启动，并提供清晰的扫描区域指示。
|
||||||
|
- 保存条形码应像点击屏幕上的识别框一样简单。
|
||||||
|
- **响应性:** 应用应在各种设备和屏幕尺寸上良好运行，特别是在移动设备上。
|
||||||
|
- **即时反馈:**
|
||||||
|
- 成功识别条形码后，应立即在视频流上用方框标出。
|
||||||
|
- 点击保存后，应有明确的提示告知用户操作成功。
|
||||||
|
- **高效管理:**
|
||||||
|
- 在历史记录页面，用户可以轻松查看所有保存的条形码。
|
||||||
|
- 提供为记录添加标签、按标签筛选、批量删除和导出的功能，以方便管理。

# 系统模式
|
||||||
|
|
||||||
|
## 架构
|
||||||
|
- **前端架构:** 单页应用（SPA），使用 React 构建，具有两个主要视图（页面）。
|
||||||
|
- **视图管理:**
|
||||||
|
- **`LiveScannerView`:** 实时扫描页面，负责摄像头访问和条形码检测。
|
||||||
|
- **`HistoryView`:** 历史记录页面，负责展示和管理已保存的数据。
|
||||||
|
- 使用 React 的条件渲染或一个轻量级的路由库来管理这两个视图之间的切换。
|
||||||
|
- **数据持久化:**
|
||||||
|
- **`IndexedDB`:** 用于在客户端存储用户的扫描历史、标签等信息。将创建一个 `DBHelper` 或类似的服务来封装数据库操作（增、删、改、查）。
|
||||||
|
|
||||||
|
## 组件模型
|
||||||
|
应用将由以下核心组件构成：
|
||||||
|
- **`App`:** 主组件，管理整体布局、当前激活的视图和底部导航栏的状态。
|
||||||
|
- **`BottomNav`:** 底部导航组件，用于在 `LiveScannerView` 和 `HistoryView` 之间切换。
|
||||||
|
- **`Scanner`:** 封装 Quagga2 逻辑，处理摄像头视频流，并在 `canvas` 上绘制结果。
|
||||||
|
- **`HistoryList`:** 显示保存在 IndexedDB 中的条形码列表。
|
||||||
|
- **`TagManager`:** 用于添加、删除和筛选标签的组件。
|
||||||
|
|
||||||
|
## 关键技术决策
|
||||||
|
- **状态管理:**
|
||||||
|
- **全局状态:** 对于当前激活的视图（实时/历史），将使用 React Context 或一个简单的状态管理库来管理。
|
||||||
|
- **本地状态:** 组件内部状态（如表单输入）将使用 `useState` 和 `useEffect`。
|
||||||
|
- **样式:** TailwindCSS 将用于快速、实用的样式设计，确保响应式布局。
|
||||||
|
- **条码扫描:** Quagga2 因其在网络环境中的灵活性和易于集成而被选中。
|
||||||
|
- **数据库交互:** 所有 IndexedDB 操作将被抽象到一个单独的模块中，以保持业务逻辑的清晰和可维护性。

# 技术背景
|
||||||
|
|
||||||
|
## 技术栈
|
||||||
|
- **pnpm:** 用于高效的依赖管理。
|
||||||
|
- **React:** 用于构建用户界面的核心库。
|
||||||
|
- **TailwindCSS:** 用于样式设计的 CSS 框架。
|
||||||
|
- **Quagga2:** 用于从视频流中解码条形码的库。
|
||||||
|
- **idb:** 一个轻量级的包装库，用于简化 IndexedDB 操作。
|
||||||
|
- **react-router-dom:** 用于在应用内进行路由和视图管理。
|
||||||
|
|
||||||
|
## 开发环境
|
||||||
|
- **构建工具:** Vite 将被用作构建工具，因为它提供了快速的开发服务器和优化的构建过程。
|
||||||
|
- **节点版本:** 建议使用最新的 LTS 版本的 Node.js。
|
||||||
|
- **包管理:** pnpm 将用于安装和管理项目依赖。
