📑 Summary
Mermaid v9.2.0 added support for custom diagrams using
lazyLoadedDiagrams
, such as the new @mermaid-js/mermaid-mindmap plugin diagram.This PR bumps the minimum required version of mermaid to v9.2.0, adds support for
lazyLoadedDiagrams
(needed to switch the Mermaid rendering code toasync
) and adds some test cases/docs.Resolves #406
📏 Design Decisions
mermaid-mindmap
is opt-in (disabled by default), since I couldn't get it to work locally, due to puppeteer CORS issues.Instead, currently it only works when hosted from a CDN like https://www.jsdelivr.com/, so it requires internet connection (and there are some GDPR issues with enabling it by default, since jsdeliver has a privacy policy).
In order to get mermaid-mindmap working locally/offline, I think we need mermaid-js/mermaid#3710 to be merged first, then we can bundle it together into a single
index.html
file.Also, to make adding
mermaid-mindmap
test cases easier, I've moved all of the test cases into atest/__fixtures__/...
folder.📋 Tasks
