# Nano Banana AI Image Editor - iFlow 文档
# Nano Banana AI 图像编辑器 - iFlow 上下文
## 项目概述
Nano Banana AI Image Editor 是一个基于 React 的 AI 图像编辑工具，用户可以通过直观的界面与 Google 的 Gemini AI 模型进行交互，实现图像生成和编辑功能。
这是一个基于 React 和 TypeScript 的 AI 图像生成与编辑应用，名为 Nano Banana AI Image Editor。它利用 Google Gemini 2.5 Flash Image 模型，提供文本到图像生成和基于自然语言的图像编辑功能。该应用具有现代化的用户界面，支持交互式画布、区域选择和历史记录管理。
## 技术栈
主要技术栈包括：
- **前端框架**: React 18, TypeScript
- **状态管理**: Zustand (应用状态), React Query (服务端状态)
- **UI 库**: Tailwind CSS
- **画布库**: Konva.js (react-konva)
- **AI 集成**: Google Generative AI SDK (Gemini)
- **数据存储**: IndexedDB (通过 idb-keyval)
- **构建工具**: Vite
- **核心框架**: React 18.x (TypeScript)
- **构建工具**: Vite 5.x
- **语言**: TypeScript (ES2020)
- **状态管理**: Zustand
- **数据获取**: TanStack Query (React Query)
- **UI 框架**:
- Tailwind CSS 3.x (样式框架)
- Radix UI (无样式的可访问 UI 组件)
- Lucide React (图标库)
- **图像处理**:
- Konva (2D 画布库)
- react-konva (Konva 的 React 封装)
- **本地存储**: IndexedDB (通过 idb-keyval 库操作)
- **AI 集成**: Google Generative AI SDK (@google/genai)
- **工具库**:

- clsx + tailwind-merge (CSS 类名合并)
- fabric.js (备用画布库)
项目结构遵循标准的 React 应用组织方式，主要源代码位于 `src/` 目录下。
## 代码风格和命名规范
## 构建和运行
### 开发环境
1. **安装依赖**:
```bash
npm install
```
2. **配置环境变量**:
- 复制 `.env.example` 为 `.env`
- 在 `.env` 文件中设置 `VITE_GEMINI_API_KEY` (必需)
- 可选设置 `VITE_ACCESS_TOKEN` 和 `VITE_UPLOAD_ASSET_URL` 以启用图像上传功能
3. **启动开发服务器**:
```bash
npm run dev
```
访问 `http://localhost:5173` 查看应用。
### 构建和部署
- **构建生产版本**:
```bash
npm run build
```
- **预览生产构建**:
```bash
npm run preview
```
### 测试
- **运行测试**:
```bash
npm run test
```
- **运行测试并监听变化**:
```bash
npm run test:watch
```
### 代码质量
- **运行 ESLint**:
```bash
npm run lint
```
## 开发约定
### 代码风格
- 使用 TypeScript 严格模式 (strict: true)
- 函数式组件为主，使用 React Hooks
- 组件文件使用 .tsx 扩展名
- 工具函数文件使用 .ts 扩展名
- 使用 ESLint 进行代码检查
- 启用严格的 TypeScript 编译选项
### 命名规范
- 组件文件和组件名使用 PascalCase (如 `Header.tsx`, `ImageCanvas`)
- 工具函数和普通文件使用 camelCase (如 `imageUtils.ts`, `useAppStore.ts`)
- 常量使用 UPPER_SNAKE_CASE
- 变量和函数使用 camelCase
- 组件 Props 接口命名为组件名 + Props (如 `ButtonProps`)
- Hook 函数以 use 开头 (如 `useAppStore`, `useImageGeneration`)
- 使用 TypeScript 进行类型安全检查
- 使用 ESLint 进行代码规范检查
- 使用 Prettier 进行代码格式化 (通过 ESLint 配置集成)
- 组件文件使用 `.tsx` 扩展名
- 工具函数文件使用 `.ts` 扩展名
## 样式和 UI 框架
### Tailwind CSS
- 使用自定义颜色方案，以香蕉黄 (banana) 为主题色
- 定义了 light 主题颜色 (背景、面板、边框、文字等)
- 使用自定义间距、阴影和动画
- 使用 tailwind-merge 和 clsx 进行类名合并
### 组件设计
- 使用 Radix UI 构建无样式的可访问组件
- 自定义 UI 组件位于 `src/components/ui` 目录
- 组件变体使用 class-variance-authority 管理
- 图标使用 Lucide React

## 核心功能模块
### 组件开发
### 1. 图像画布 (ImageCanvas)
- 使用 Konva 和 react-konva 实现图像显示和编辑
- 支持图像缩放、平移
- 实现画笔工具进行遮罩绘制
- 支持图像下载功能
- 组件应保持较小的体积（建议小于200行）
- 使用函数式组件和 React Hooks
- 组件应具有明确的接口（Props）
- 尽可能使用 TypeScript 进行类型定义
### 2. 提示词编辑 (PromptComposer)
- 用户输入提示词生成图像
- 提供提示词建议功能
- 集成 AI 模型参数调整 (如风格、质量等)
### 状态管理
### 3. 历史记录 (HistoryPanel)
- 显示生成的图像历史
- 支持历史图像的查看和重新编辑
- 使用 IndexedDB 存储历史数据
- 全局状态使用 Zustand 管理 (`src/store/useAppStore.ts`)
- 服务端状态使用 React Query 管理
- 组件内部状态使用 React 的 useState 和 useReducer
### 4. 状态管理 (useAppStore)
- 使用 Zustand 管理全局状态
- 存储画布状态、用户设置、历史记录等
- 提供状态操作方法
### 测试
### 5. AI 服务 (geminiService)
- 集成 Google Gemini AI 模型
- 实现图像生成和编辑功能
- 处理与 AI 模型的交互
- 使用 Jest 和 React Testing Library 进行测试
- 测试文件放在 `src/__tests__` 目录下
- 测试文件名应与被测试文件名对应，加上 `.test.tsx` 或 `.test.ts` 后缀
## 开发环境配置
### 贡献指南
1. 安装依赖: `npm install`
2. 启动开发服务器: `npm run dev`
3. 构建生产版本: `npm run build`
4. 代码检查: `npm run lint`
## 注意事项
- 项目使用 IndexedDB 存储图像数据，需要注意存储空间管理
- AI 功能需要配置 Google API 密钥
- 图像处理功能依赖浏览器 Canvas API
- 移动端适配需要特别关注界面布局和交互
1. 遵循既定的代码风格和项目结构
2. 保持组件在 200 行以内
3. 维护类型安全，严格使用 TypeScript 和正确定义
4. 彻底测试，确保键盘导航和可访问性
5. 记录更改，更新 README 并添加内联注释
6. 遵守 AGPL-3.0 许可证
