Topic on Extension talk:Mermaid/Flow

We are using Mediawiki 1.36 with Mermaid Extension 3.1.0, which includes Mermaid 8.14.0.

An update with jarn install did not update mermaid.min.js to newer versions.

A manual update of mermaid.min.js to Version 10.4 failed, since the JavaScript could not be loaded.

Is there a practicable way to update the included version of mermaid.min.js to current version 10.x?

Hello.

Try to use the mermaid.js file instead of mermaid.min.js. Also the variable $wgResourceLoaderDebug = true; solves the problem (but this is not so much a solution as the reason why it happens).

@Mikasa7, can you please provide a step-by-step instruction for dummies how to upgrade to Mermaid 10.x? Would be greatly appreciated!

Or could somebody who knows how to do it create a new version of the Extension with the latest Mermaid version included?

Hello @Tom-Wiming,

To update version of mermaid.js you need to clone repository: https://github.com/SemanticMediaWiki/Mermaid

Execute the commands:

• npx npm-check-updates -u (or manually edit package.json - change the mermaid version to the new one)

• npm install

At execution time there may be errors related to file copying, but this is OK.

The updated version of the file will be located at:

resources/mermaid.min.js

If MediaWiki cannot load new version of the file correctly replace in extension.json row resources/mermaid.min.js with resources/mermaid.js

Afterwards you should copy file node_modules/mermaid/dist/mermaid.js to resources folder.

I hope I've been helpful

Thanks @Mikasa7! I indeed got the copying error messages, but ignored them. Also, it didn't work with "mermaid.min.js" (the code threw an exception in the browser), but using the unpacked "mermaid.js" works.
