Coming Soon: Price Pipeline Health Widget (join the sprint)
Sprint starts next week — engineers, designers and beta users welcome (DM me).
Context
Pocket Portfolio’s promise is reliability: never show 0.00 and always explain a number. We already run a time-boxed, multi-provider quoting engine (Yahoo Finance, Chart API, Stooq) with deterministic fallbacks. The missing piece is visibility into the pipeline: which provider won, who failed, and when fallbacks/outages happen.
What’s new (planned)
- US1 — Provider health logging: Record success/failure events, timestamps, and fallback usage (in-memory for dev, Redis/Upstash for prod).
- US2 — Health endpoint:
GET /api/health-price returns aggregated provider metrics (lastSuccess, lastFailure, failureCount, activeFallback), edge-tested and rate-limited.
- US3/US4 — Typed services & hooks:
getPriceHealth() + usePriceHealth() (30s polling) → { health, loading, error }.
- US5 — Health Card UI: Colour-coded badges per provider:
- Fresh (green) < 30s,
- Fallback (amber) < 1 min,
- Unhealthy (red) ≥ 5 min without success.
- US6 — Dashboard integration: Sits beside Live Prices for instant status.
- US7/US8 — Shared logic & config: Extract logging, wire
UPSTASH_REDIS_REST_URL/UPSTASH_REDIS_REST_TOKEN; fallback to in-memory when unset.
- US9 — Documentation: API contract, persistence, UI states, extension.
- US10/US11 (optional): Symbol-level freshness and extended outage alerts (pending design/business sign-off).
How it works (high level)
- Parallel + budget: Query providers in parallel with an abortable time budget; first valid wins.
- LKG safety: If all fail, serve last-known good marked stale.
- Health layer: Each call records success/failure; the health endpoint aggregates; a polling hook updates the UI; the Health Card renders Fresh/Fallback/Unhealthy.
Impact
- Users: Trust the numbers; know when data is fresh or on fallback.
- Engineers: Faster incident triage; a clear contract for the quote pipeline.
- Designers: Opportunity to model a friendly, accessible status language.
