I started Tolaria in Swift but met very real limitations especially in the Markdown editor part. It's very hard to build something that is Notion like in that department with Swift.

But give it a try because Tauri is very fast

I just built a markdown-style editor for iOS that is highly performant with files of 5000 lines.

Every keystroke is restyled in under 8ms: no debouncing, no delayed rendering. 20 rapid keystrokes are processed in 150ms with full restyling after each one. Tag and boolean searches complete in under 20ms. Visible-range rendering is 25x faster than full-document styling. 120Hz screen refresh supported.

App file size is 722 KB.

If I can do it on iOS then it's must be 10x easier on macOS.

At least for me it’s not about speed, but the npm ecosystem: I try to avoid running npm deps in my home computer (if any, I run them in VMs, but a KB should run in the host I believe)

Agree, the npm ecosystem is increasingly becoming an security liability.

Curious if you looked at using SwiftDown (https://github.com/qeude/SwiftDown), MarkupEditor (https://github.com/stevengharris/MarkupEditor) or any other libraries for live/WYSIWYG Markdown editing.
