+
+一个集成了AI功能的Next.js网页应用，与draw.io图表无缝结合。通过自然语言命令和AI辅助可视化来创建、修改和增强图表。
+
+https://github.com/user-attachments/assets/b2eef5f3-b335-4e71-a755-dc2e80931979
+
+## 功能特性
+
+-   **LLM驱动的图表创建**：利用大语言模型通过自然语言命令直接创建和操作draw.io图表
+-   **基于图像的图表复制**：上传现有图表或图像，让AI自动复制和增强
+-   **图表历史记录**：全面的版本控制，跟踪所有更改，允许您查看和恢复AI编辑前的图表版本
+-   **交互式聊天界面**：与AI实时对话来完善您的图表
+-   **AWS架构图支持**：专门支持生成AWS架构图
+-   **动画连接器**：在图表元素之间创建动态动画连接器，实现更好的可视化效果
+
+## **示例**
+
+以下是一些示例提示词及其生成的图表：
+
+<div align="center">
+<table width="100%">
+  <tr>
+    <td colspan="2" valign="top" align="center">
+      <strong>动画Transformer连接器</strong><br />

+      <img src="./public/gcp_demo.svg" alt="GCP架构图" width="480" />
+    </td>

+      <p><strong>提示词：</strong> 使用**AWS图标**生成一个AWS架构图。在这个图中，用户连接到托管在实例上的前端。</p>

+  </tr>
+</table>
+</div>
+
+## 工作原理
+
+本应用使用以下技术：
+
+-   **Next.js**：用于前端框架和路由
+-   **Vercel AI SDK**（`ai` + `@ai-sdk/*`）：用于流式AI响应和多提供商支持
+-   **react-drawio**：用于图表表示和操作
+
+图表以XML格式表示，可在draw.io中渲染。AI处理您的命令并相应地生成或修改此XML。
+
+## 多提供商支持
+
+-   AWS Bedrock（默认）
+-   OpenAI / OpenAI兼容API（通过 `OPENAI_BASE_URL`）
+-   Anthropic
+-   Google AI
+-   Azure OpenAI
+-   Ollama
+-   OpenRouter
+-   DeepSeek
+
+注意：`claude-sonnet-4-5` 已在带有AWS标志的draw.io图表上进行训练，因此如果您想创建AWS架构图，这是最佳选择。
+
+## 快速开始
+
+### 安装
+
+1. 克隆仓库：
+
+```bash
+git clone https://github.com/DayuanJiang/next-ai-draw-io
+cd next-ai-draw-io
+```
+
+2. 安装依赖：
+
+```bash
+npm install
+# 或
+yarn install
+```
+
+3. 配置您的AI提供商：
+
+在根目录创建 `.env.local` 文件：
+
+```bash
+cp env.example .env.local
+```
+
+编辑 `.env.local` 并配置您选择的提供商：
+
+-   将 `AI_PROVIDER` 设置为您选择的提供商（bedrock, openai, anthropic, google, azure, ollama, openrouter, deepseek）
+-   将 `AI_MODEL` 设置为您要使用的特定模型
+-   添加您的提供商所需的API密钥
+
+请参阅上面的[多提供商支持](#多提供商支持)部分了解特定提供商的配置示例。
+
+4. 运行开发服务器：
+
+```bash
+npm run dev
+```
+
+5. 在浏览器中打开 [http://localhost:3000](http://localhost:3000) 查看应用。
+
+## 部署
+
+部署Next.js应用最简单的方式是使用Next.js创建者提供的[Vercel平台](https://vercel.com/new)。
+
+查看[Next.js部署文档](https://nextjs.org/docs/app/building-your-application/deploying)了解更多详情。
+
+或者您可以通过此按钮部署：
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2FDayuanJiang%2Fnext-ai-draw-io)
+
+请确保在Vercel控制台中**设置环境变量**，就像您在本地 `.env.local` 文件中所做的那样。
