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)
replyAgree, the npm ecosystem is increasingly becoming an security liability.
replyI just built a markdown-style editor for iOS that is highly performant with files of 5000 lines.
replyEvery 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.
