feat: add source-map support for editor DOM mapping#347
Open
Conversation
Backport the react-source-loc Vite plugin from the app-builder template. The plugin injects `data-source="<file>:<line>:<col>"` attributes onto native JSX elements so the editor can map DOM elements back to their source location. Also enables `sourcemap: true` in the Vite build config. Co-authored-by: Isaac
