# PlantAI 桌面端(Electron 瘦客户端)
|
||||
|
||||
把 `ui/` 的 Vue 单页应用封装成 Electron 桌面 App。**后端(Python/BFF/向量库)不打包进 App**,桌面端只是一个指向后端的瘦客户端。
|
||||
|
||||
## 原理
|
||||
|
||||
- Electron 主进程内起一个**只监听 `127.0.0.1`** 的本地 HTTP 服务(`server.js`):
|
||||
- 静态托管 `renderer-dist`(即 `ui/dist` 的副本);
|
||||
- 把 `/api` 反代到**可配置的后端地址**。
|
||||
- 前端源码 `ui/` **零改动**、后端 **CORS 零改动**:相对路径 `/api` 与 SSE 流靠同源天然可用。
|
||||
- 后端地址配置(`config.js`)优先级:`PLANTAI_BFF_URL` 环境变量 > `userData/config.json` > 默认 `http://127.0.0.1:8090`。可在应用内菜单「设置 → 后端地址…」修改(保存后重载)。
|
||||
|
||||
## 环境要求
|
||||
|
||||
- Node.js ≥ 18、npm。
|
||||
|
||||
## 开发运行
|
||||
|
||||
```bash
|
||||
cd desktop
|
||||
npm install
|
||||
npm run build:ui # 先构建前端(ui/)并复制产物到 renderer-dist/
|
||||
npm start # 启动 Electron 窗口
|
||||
```
|
||||
|
||||
## 打包
|
||||
|
||||
```bash
|
||||
cd desktop
|
||||
npm run dist:linux # AppImage + deb
|
||||
npm run dist:win # NSIS 安装包 + portable
|
||||
npm run dist:mac # dmg + zip(必须在 macOS 上构建)
|
||||
```
|
||||
|
||||
## 跨平台注意事项
|
||||
|
||||
- `package.json` 的 `author` / `homepage` 为占位值,发布前请替换为真实作者与主页(deb 等安装包会写入这些元数据)。
|
||||
|
||||
- **macOS 安装包必须在 macOS 机器上构建**(或 macOS CI);Linux 无法产出 dmg。
|
||||
- **Windows 可从 Linux 交叉打包**,个别步骤(图标/rcedit)可能依赖 wine;更稳的方式是用 CI 三平台矩阵产出。
|
||||
- 应用图标:`build/icon.png`(512×512,PNG)。electron-builder 会据此自动派生 `.ico`/`.icns`;未提供时使用默认 Electron 图标。
|
||||
- **后端可达性**:桌面端要能访问配置的后端地址(公网 HTTPS / VPN / SSH 隧道均可),属网络环境问题,非代码范围。
