More details
With this app, you can keep the mermaid source code as part of the page, but don't bother with copy-pasting rendered images from the mermaid editor every time you make a change.
There are numerous benefits to storing code as part of the page:
- Native confluence version control.
- The app does not store or egress any data (it does not even have permissions).
- Even if app breaks - your source code remains accessible so you can always render it manually.
