Phase 11 Plan 2: Lazy-Load Non-Critical Routes Summary

Lazy-loaded 5 non-critical authenticated route components, reducing the main JS bundle from 264.63 kB to 180.17 kB and emitting 5 separate route chunks, satisfying PERF-03.

What Was Built

Tasks 1-4 — Router lazy-loading

frontend/src/router/index.js updated:

• Removed static import statements for TopicsView, DocumentView, SettingsView, CloudStorageView, CloudFolderView.
• Replaced each with an inline () => import('../views/...View.vue') dynamic import on the route's component field.
• Kept FileManagerView as the sole static synchronous import (decision D-10). A comment block in router/index.js documents the rationale.
• Kept /folders/:folderId using the synchronous FileManagerView component — no new chunk needed since the component is already in the initial bundle.
• Preserved all existing lazy imports for admin children, auth views, SharedView, and AdminLayout.

Acceptance criterion confirmed: grep "import .*View" frontend/src/router/index.js returns only FileManagerView.

Task 5 — Extended router guard tests

frontend/src/router/__tests__/router.guard.test.js extended with 15 new tests across 2 new describe blocks:

• router — admin guard extended with: non-admin blocked from /admin/users and /admin/quotas (child route inheritance via to.matched.some()), admin redirected away from /settings and /cloud (D-09)
• router — refresh-before-guard (new): verifies refresh() is called when accessToken is null, redirect to /login when refresh fails, no refresh call for public routes
• router — lazy-loaded routes resolve (new): verifies all 5 newly-lazy routes (/topics, /topics/:name, /document/:id, /settings, /cloud, /cloud/:provider/:folderId) navigate correctly for authenticated regular users; /folders/:folderId and /shared also covered

All 234 tests pass (up from 219 in Plan 11-01).

Task 6 — Build verification

npm run build succeeds; route chunks emitted:

Chunk	Size
CloudFolderView-*.js	1.99 kB
CloudStorageView-*.js	2.32 kB
DocumentView-*.js	9.17 kB
TopicsView-*.js	10.98 kB
SettingsView-*.js	60.72 kB
Main bundle (index-*.js)	180.17 kB (was 264.63 kB)

Main bundle reduction: 84.46 kB raw (~32%).

Verification

• rg "import .*View" frontend/src/router/index.js returns only FileManagerView — confirmed
• Admin child routes remain lazy-loaded — confirmed
• npm test: 234 tests pass, 30 test files
• npm run build: succeeds, split route chunks emitted

Deviations from Plan

None — plan executed exactly as written.

Known Stubs

None.

Threat Flags

None — this plan makes no network, auth, or schema changes. Guard behavior is unchanged; only the loading strategy for view components was modified.

Self-Check: PASSED

• frontend/src/router/index.js: modified, only FileManagerView statically imported
• frontend/src/router/__tests__/router.guard.test.js: modified, 15 new tests
• Commit 4fa07b3 exists in git log
• Build output shows 5 route chunk files
