## Summary
Add support for self-hosted draw.io instances via build-time configuration.
## Problem
In some corporate environments, `embed.diagrams.net` is blocked by network policies.
Users cannot use the application without access to the default draw.io embed URL.
## Solution
- Add `NEXT_PUBLIC_DRAWIO_BASE_URL` environment variable support
- Pass the `baseUrl` prop to the `DrawIoEmbed` component
- Configure Dockerfile to accept build-time argument for the draw.io URL
## Usage
```yaml
# docker-compose.yaml
services:
drawio:
image: jgraph/drawio:latest
ports:
- "8080:8080"
next-ai-draw-io:
build:
context: .
args:
- NEXT_PUBLIC_DRAWIO_BASE_URL=http://drawio:8080
```
Or build directly:
```bash
docker build --build-arg NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080 -t next-ai-draw-io .
```
**Note:** This is a build-time configuration. To change the draw.io URL, you need to rebuild the Docker image.
