A proof-of-concept code editor with syntax highlighting that uses

• highlighted-pre-over-textarea approach (like react-simple-code-editor)
• web-tree-sitter for incremental parsing
• diff-match-patch via json0-ot-diff for computing text diffs (needed for using tree-sitter)
• React for DOM updates

For context, see codemirror/dev#109

To start:

npm start to serve the React app.

node server.js to serve the Node.js server (required for WASM issues).

This is a very rough prototype and there are known issues.

Feel free to file new issues!
