From 745be7ee8b050455be982796bbb5c5ef94b00e31 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Hartmut=20N=C3=B6renberg?= Date: Wed, 1 Apr 2026 22:44:41 +0200 Subject: [PATCH] fix(dashboard): scope localStorage key by userId to prevent cross-user layout bleed (#27) New users on a shared device were picking up a previous user's stale (potentially empty) dashboard layout from localStorage because the key "capakraken_dashboard_v1" was not user-scoped. - useDashboardLayout: key is now capakraken_dashboard_v1_{userId}; userId is resolved via trpc.user.me before touching localStorage - Initial state falls back to createDefaultDashboardLayout() until userId resolves, then hydrates from the user-scoped key - DB layout still wins over localStorage when it has data (unchanged) - E2E test suite covers: new-user flow, modal widget list, add widget persists after reload, cross-user localStorage isolation - plan.md: added ticket #27 implementation plan Co-Authored-By: claude-flow --- .../e2e/dev-system/dashboard-widgets.spec.ts | 286 ++++++++++++++++++ apps/web/src/hooks/useDashboardLayout.ts | 44 ++- plan.md | 41 ++- 3 files changed, 360 insertions(+), 11 deletions(-) create mode 100644 apps/web/e2e/dev-system/dashboard-widgets.spec.ts diff --git a/apps/web/e2e/dev-system/dashboard-widgets.spec.ts b/apps/web/e2e/dev-system/dashboard-widgets.spec.ts new file mode 100644 index 0000000..541a438 --- /dev/null +++ b/apps/web/e2e/dev-system/dashboard-widgets.spec.ts @@ -0,0 +1,286 @@ +/** + * E2E tests for the dashboard widget flow. + * + * Coverage: + * 1.
