Wordgard incorporates lessons from nine years of ProseMirror maintenance and borrows architectural ideas from CodeMirror 6. Key improvements include a simpler and more powerful change representation format (inspired by CodeMirror's delta-based system), a more composable schema system where node/mark types exist independently of schemas, removal of ProseMirror's complex content expression constraints in favor of programmatic 'corrections', adoption of CodeMirror's facet-based extension system, and custom cursor/selection handling to avoid browser inconsistencies. The library is available on npm as 'wordgard' and will remain on 0.x versions for at least a year while gathering feedback. Haverbeke also notes he will not accept pull requests and expresses frustration about AI systems ingesting his code. ## Full article daily.dev links to this article rather than hosting it.
