Features

This plugin enables you to embed interactive drawio diagrams in your documentation. Simply add your diagrams like you would any other image:

You can either use diagrams hosted within your own docs. Absolute as well as relative paths are allowed:

Absolute path:
![](/assets/my-diagram.drawio)

Same directory as the markdown file:
![](my-diagram.drawio)

Relative directory to the markdown file:
![](../my-diagram.drawio)


Or you can use external urls:
![](https://example.com/diagram.drawio)

Additionally this plugin supports multi page diagrams by using the alt text to select the pages by name:

![Page-2](my-diagram.drawio)
![my-custom-page-name](my-diagram.drawio)

Setup

Install plugin using pip:

pip install mkdocs-drawio

Add the plugin to your mkdocs.yml

plugins:
  - drawio

Configuration Options

By default the plugin uses the official url for the minified drawio javascript library. To use a custom source for the drawio viewer you can overwritte the url. This might be useful in airlocked environments.

If you want to use a self-hosted JavaScript viewer file. You should download the latest version from the official drawio repo.

plugins:
  - drawio:
      viewer_js: "https://viewer.diagrams.net/js/viewer-static.min.js"

Further options are:

plugins:
  - drawio:
      toolbar: true  # control if hovering on a diagram shows a toolbar for zooming or not (default: true)
      tooltips: true # control if tooltips will be shown (default: true)
      border: 10     # increase or decrease the border / margin around your diagrams (default: 5) 

Material Integration

If you are using the Material Theme and want to use the instant-loading feature. You will have to configure the following:

In your mkdocs.yaml:

theme:
  name: material
  features:
    - navigation.instant

plugins:
  - drawio

extra_javascript:
  - https://viewer.diagrams.net/js/viewer-static.min.js
  - javascripts/drawio-reload.js

Add docs/javascripts/drawio-reload.js to your project:

document$.subscribe(({ body }) => {
  GraphViewer.processElements()
})

How it works

1. mkdocs generates the html per page
2. mkdocs-drawio attaches to the on_post_page event. For more details, please have a look at the event lifecycle documentation
3. Adds the drawio viewer library
4. Searches through the generated html for all img tags that have a source of type .drawio
5. Replaces the found img tags with mxgraph html blocks (actual drawio diagram content). For more details, please have a look at the official drawio.com documentation.
