How to integrate diagrams.net (draw.io) with your GitHub repo

Note: Images in markdown are cached and can take five minutes to update

Using VS Code locally, on github.dev or on CodeSpaces (Recommended)

This method does not require any OAuth or GitHub app approvals and defaults to offline mode. 🎉

Using the [Draw.io Visual Studio Code extension], you can do this in github.dev, Codespaces or locally on VS Code.

1. Open the repository you want to create the diagram in
2. Press . to open github.dev (or use Codespaces, or clone and use VS Code locally)
3. Install the [Draw.io Visual Studio Code extension]
4. Open or save a file ending with .drawio.svg or .drawio.png (svg is recommended). This will open the draw.io editor in VS Code.
5. Reference the file using a relative link in markdown like you would reference any file ![Label](relative link)
6. It will now live-update, you can use PRs to review changes, and you didn't need to authorize anything! 🚀
