| description | Non-functional requirements checklist for NEAN features |
Purpose
Ensure NEAN stories address NFRs. Complements security policies and stack conventions.
NEAN-specific concerns (always consider)
- PostgreSQL efficiency — query patterns, indexing strategy, pagination for large tables, N+1 query prevention
- Schema migrations — TypeORM migrations need rollback strategy; test migrations in staging first
- API resilience — idempotency keys for mutations, rate limiting on expensive/public endpoints, graceful degradation
- Angular rendering — lazy loading modules, OnPush change detection where appropriate, bundle size monitoring
- Caching — consider caching layer for frequently accessed data (Redis, in-memory); cache invalidation strategy
- Operability — config/env differences, safe rollout/rollback, feature flags if risky, health checks
For standard concerns, output format, and flexibility rules, see /shared-nfr.
NEAN-specific standard concern additions
- Performance: <200ms p95, bundle size budgets
- Reliability: retry logic for external services
- Security/privacy: GDPR considerations
- Observability: structured logging
- Accessibility: ARIA labels on UI changes
