Vendix Frontend Cache
Source of Truth
Representative patterns live in:
.../super-admin/dashboard/services/super-admin-dashboard.service.ts.../organization/dashboard/services/organization-dashboard.service.ts.../store/reports/services/reports-data.service.ts
Current Reality
Vendix does not use one single cache shape.
Current patterns include:
- service instance fields with TTL timestamps
- module-level
Mapcaches keyed by params/entity ids - helper methods like
withCache(key, factory) shareReplay({ bufferSize: 1, refCount: true })and alsorefCount: false
Do not document a false rule that Angular service instances are always recreated on navigation or that all caches must be static globals.
Rules
- Pick cache shape based on the endpoint usage pattern, not ideology.
- Use stable cache keys when params/date ranges/entity ids change the result.
- Invalidate cache after writes that make the cached view stale.
- Avoid caching obviously real-time or rapidly changing streams unless the feature explicitly accepts staleness.
- Use short TTLs for dashboards/stats unless there is a stronger product reason.
