The current build stack uses `react-scripts@3.0.1` with `sass-loader@10.5.2`; that loader calls Dart Sass through the legacy `render()` API.\n\n## Why it matters\n\nDart Sass 2.0.0 will remove the legacy JS API, so this is future breakage rather than just noisy output.\n\n## Acceptance criteria\n\n- `npm run build` completes without any `legacy-js-api` Sass warnings.\n- The SCSS/CSS output remains equivalent for the existing app.\n- The fix keeps the CRA 3 build wrapper working on the current Node baseline.","author":{"url":"https://github.com/yuyu1815","@type":"Person","name":"yuyu1815"},"datePublished":"2026-05-04T08:49:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/805/algorithm-visualizer/issues/805"}
