Mermaid line color / arrows not visible in Backstage dark theme #6

Closed dmckernanacv closed 2 years ago

dmckernanacv commented 2 years ago

Hello, me again!

Just wanted to know if you could release a version of this that's compatible with the stock dark mode in Backstage

You could either hardcode a different grey value for the mermaid lines in Mermaid.tsx

      mermaid.initialize({ themeVariables: { lineColor: '#666', arrowheadColor: '#666' } })

(Right before the render possibly)

Or alternatively, have a way to supply theme variables via backstage plugin config in the config.yaml?

Thanks!

Making the mermaid configuration customisable definitely sounds feature.

I'm fairly busy this week, but if you want to give it a shot you can probably extend the MermaidProps https://github.com/johanneswuerbach/backstage-plugin-techdocs-addon-mermaid/blob/main/src/Mermaid/Mermaid.tsx#L25 to allow users to provide configurations similar to the in-tree addons https://github.com/backstage/backstage/blob/master/plugins/techdocs-module-addons-contrib/src/ReportIssue/ReportIssue.tsx#L56
