Remove Performance tab, PerformanceStats component, settings toggle,
Web Vitals observers from tracking script, and all related API types
and SWR hooks. Duration tracking is preserved.
Performance metrics moved from dashboard into a new Performance tab.
Fixed null handling so "No data" shows instead of misleading zeros.
Script no longer sends INP=0 when no interaction occurred.
Replaces 4 separate frustration API calls with single useBehavior hook.
Removes manual fetchData, loading/error state, and refresh interval—SWR
handles caching, revalidation, and error state automatically.
Replace useDashboardOverview, useDashboardPages, useDashboardLocations,
useDashboardDevices, useDashboardReferrers, useDashboardPerformance, and
useDashboardGoals with a single useDashboard hook that calls the existing
/dashboard batch endpoint. This endpoint runs all queries in parallel on
the backend and caches the result in Redis (30s TTL).
Reduces dashboard requests from 12 to 6 per refresh cycle (50% reduction).
At 1,000 concurrent users: ~6,000 req/min instead of 12,000.
Dashboard filtering: FilterBar pills, AddFilterDropdown with dimension/
operator/value steps, URL-serialized filters, all SWR hooks filter-aware.
Custom event properties: pulse.track() accepts props object, EventProperties
panel with auto-discovered key tabs and value bar charts, clickable goal rows.
Updated changelog with both features under v0.13.0-alpha.
Introduce buildQuery helper and createListFetcher factory to eliminate
near-identical param building and list endpoint boilerplate. File reduced
from ~600 to ~310 lines (~48% reduction) with identical runtime behavior.
