The canvas now fills the window and the chat floats on its right. draw.io is served from our own origin (public/drawio, downloaded at build time and checked against the release's SHA-256), so the app can drive the editor directly: - every AI change becomes a version card with a thumbnail; compare, restore or undo it, and Ctrl+Z on the canvas takes an AI change back in one step - shapes the AI just changed are highlighted on the canvas - selected shapes appear as a chip and are sent to the model - the app's own canvas toolbar, shape library and page tabs replace draw.io's chrome - new start screen, session rename and switcher, open .drawio files - settings split into Models & keys, Appearance, Advanced and About - phones switch between canvas and chat - dark mode keeps the diagram on a white sheet and no longer flashes With an external draw.io (NEXT_PUBLIC_DRAWIO_BASE_URL) the app falls back to draw.io's own toolbar and the features above that need same origin are off. The chat logic moved from the 1500-line chat panel into a chat engine plus small UI components; zustand holds canvas, versions, settings and UI state.

# 离线部署
|
|
|
|
Next AI Draw.io 自带一份 draw.io。`npm run build`（包括 Docker 构建）会把 draw.io 的发布包下载到 `public/drawio`，只下载一次，应用从 `/drawio` 提供它。使用时浏览器不会访问 `embed.diagrams.net`，所以只要构建时能联网，应用就能在离线网络或内网里使用。
|
|
|
|
## Docker Compose 设置
|
|
|
|
1. 克隆仓库并在 `.env` 文件中定义 API 密钥。
|
|
2. 运行 `docker compose up -d`（使用仓库里的 `docker-compose.yml`）。
|
|
3. 打开 `http://localhost:3000`。
|
|
|
|
不需要单独的 draw.io 容器。
|
|
|
|
## 构建机器不能联网时
|
|
|
|
构建会从 [draw.io 发布页](https://github.com/jgraph/drawio/releases) 下载 `draw.war`（约 50 MB）。如果构建机器访问不了 GitHub：
|
|
|
|
- 在另一台机器上下载 `scripts/fetch-drawio.mjs` 里写明的那个版本的 `draw.war`，解压到 `public/drawio`（删掉 `WEB-INF` 和 `META-INF`），再把版本号（例如 `v32.0.2`）写进 `public/drawio/.version`。构建时就会使用这份副本。
|
|
- 或者在能联网的机器上构建镜像，再拷到离线网络里。
|
|
|
|
## 使用单独的 draw.io 服务器（可选）
|
|
|
|
仍然可以用构建时变量 `NEXT_PUBLIC_DRAWIO_BASE_URL` 让应用使用别处的 draw.io，比如 `jgraph/drawio` 镜像：
|
|
|
|
```yaml
|
|
services:
|
|
drawio:
|
|
image: jgraph/drawio:latest
|
|
ports: ["8080:8080"]
|
|
next-ai-draw-io:
|
|
build:
|
|
context: .
|
|
args:
|
|
- NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080
|
|
ports: ["3000:3000"]
|
|
env_file: .env
|
|
depends_on: [drawio]
|
|
```
|
|
|
|
使用外部 draw.io 时，应用改用 draw.io 自己的工具栏，以下功能不可用：标出 AI 改了哪些图形、针对选中的图形提问、应用自己的画布工具栏、用 Ctrl+Z 撤回 AI 的修改。浏览器不允许页面控制来自其他域名的编辑器。
|
|
|
|
**`NEXT_PUBLIC_DRAWIO_BASE_URL` 必须是用户浏览器可访问的地址。**
|
|
|
|
| 场景 | URL 值 |
|
|
|----------|-----------|
|
|
| 本地主机 (Localhost) | `http://localhost:8080` |
|
|
| 远程/服务器 | `http://YOUR_SERVER_IP:8080` |
|
|
|
|
**切勿使用** Docker 内部别名（如 `http://drawio:8080`），因为浏览器无法解析它们。
