👉 You can test the plugin here
Add the dependencies and plugin to index.html
<script>
window.$docsify = {
...,
mermaidConfig: {
querySelector: ".mermaid",
}
...,
};
</script>
<!-- Import D3.js -->
<script src="//cdn.jsdelivr.net/npm/d3@7"></script>
<!-- Import Mermaid -->
<script type="module">
import mermaid from "https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs";
mermaid.initialize({ startOnLoad: true });
window.mermaid = mermaid;
</script>
<!-- Import Docsify-mermaid-zoom -->
<script src="//unpkg.com/[email protected]/dist/docsify-mermaid.js"></script>
<script src="//unpkg.com/docsify-mermaid-zoom/dist/docsify-mermaid-zoom.js"></script>You can configure min/max scale and disable the zoom pannel.
The pannel provides two buttons. The first button activates the zoom feature on the mermaid diagram. The second one allows to reset the zoom. This pannel can be disabled.
You can also activate the zoom on the diagram by double clicking on it. The diagram will return to its original scale once it leaves the viewport on your screen.
You can configure minimum zoom and maximum zoom.
You can also disable the zoom pannel. Zoom will still work if you double click on a diagramm.
<script>
window.$docsify = {
...,
mermaidZoom: {
minimumScale: 1,
maximumScale: 5,
zoomPannel: true
},
...,
}
