The React frontend is complete (Phases 1-3); the lit-html fallback is dead
(its vendor globals were removed in Phase 3). Delete it and the scaffolding:
- Delete the entire src/meshcore_hub/web/static/js/spa/ lit-html tree,
LitBridge.tsx, and legacy.d.ts.
- Remove the @legacy alias from vite.config.ts and tsconfig.json.
- Remove lit-html and qrcodejs from package.json (both unused now).
- Remove the lit-html fallback {% else %} branch from spa.html — the Vite
build is now required to serve the UI (no fallback bundle).
Tests (fallback no longer exists):
- test_home/advertisements/nodes/messages.py: assert the React mount point
(id="app") instead of a bundled-or-fallback script tag.
- test_caching.py: JS-cache tests are header-only (static JS is bundled into
dist/, absent in test env; the middleware sets headers on 404 too); the
dist-bundle HTML test drops its fallback branch.
Docs:
- AGENTS.md: new Frontend (React) section (host-run npm/vite/tsc toolchain,
react-chartjs-2/react-leaflet/react-qr-code, CSS load order); clarified the
compose-stack rule to exempt frontend tooling.
- REACT_MIGRATION.md: Phase 4 complete, final file structure, decisions.
Verified: tsc --noEmit clean, npm run build, full pytest (1463 passed,
22 skipped), pre-commit (passed).
