# grocery-price-dashboard
|
| 13 |
+
|
| 14 |
+
Read-only public dashboard for the [grocery-price-rag](https://github.com/Arjun10g/grocery-price-rag) Canadian grocery price ingestion pipeline.
|
| 15 |
+
|
| 16 |
+
Live data: 165k+ price observations across StatCan provincial averages, Loblaws + Sobeys retailer APIs, Schema.org markup on long-tail grocers, and crowdsourced Open Food Facts. Refreshed every two weeks via Cloud Run + Cloud Scheduler.

## Pages

|
| 27 |
+
| Route | What it does |
|
| 28 |
+
|---|---|
|
| 29 |
+
| `/` | Search + recent observations feed + table-count overview |
|
| 30 |
+
| `/search?q=...` | Product name + brand search (ILIKE; pg_trgm hybrid is future work) |
|
| 31 |
+
| `/products/[id]` | Price history chart, latest by retailer, all observations |
|
| 32 |
+
| `/sources` | Source confidence + recent pipeline runs (succeeded/failed/dlq) |
|
| 33 |
+
| `/stores` | 1,931 grocery stores grouped by province (from osm_overpass) |
|

## Local dev
|
| 36 |
+
|
| 37 |
+
```bash
|
| 38 |
+
cp .env.example .env.local
|
| 39 |
+
# Fill in NEXT_PUBLIC_SUPABASE_URL + NEXT_PUBLIC_SUPABASE_ANON_KEY
|
| 40 |
+
# (anon key is intentionally public — RLS gates what's readable)
|
| 41 |
+
|
| 42 |
+
npm install
|
| 43 |
+
npm run dev # http://localhost:3000

## What this dashboard is NOT
|
| 47 |
+
|
| 48 |
+
- Not a search engine (no semantic / embedding queries — those columns exist in the ingestion DB but the dashboard sticks to ILIKE)
|
| 49 |
+
- Not a notification service (no auth, no saved searches)
|
| 50 |
+
- Not a price-prediction tool (every row is a sighting, not a forecast)
|
| 51 |
+
- Not real-time (re-validates server-side at most once per minute via `revalidate`)
