Brewery index — data requirements

/breweries (app/features/breweries/routes/breweries.tsx) is built and live. This document inventories every piece of data the page needs, section by section: what's already wired to real data, what's filler pending backend work, and what the backend would need to add to close each gap.

Status legend

• ✅ Available — real data, already wired up.
• ⚠️ Partial — an endpoint exists but is missing a field the design needs.
• ❌ Missing — no backend support at all; page currently shows filler.

1. Page header

Static copy only. No data.

2. Featured brewery

Field	Status	Current source	Gap
Name, description, address, location	✅	GET /api/brewery (BreweryDto)	—
"Editorially featured" selection	❌	none — defaults to the most recently created brewery	No IsFeatured flag or rotation concept anywhere in BreweryPost. Needs a field + an admin toggle, or a scheduled rotation query, to back the "THIS WEEK" cadence the badge implies.
Founded year	❌	none	BreweryPost has no founding date. Would need a new column (distinct from CreatedAt, which is post-creation time, not the brewery's actual founding).
Beers listed count	❌	none	No beer-count aggregate exists. Blocked on the beers gap below.
House style	❌	none	No style/tag field on BreweryPost, and no aggregate over its beers' styles either.

3. Breweries near you

Field	Status	Current source	Gap
Nearby breweries by coordinates + radius	✅	GET /api/brewery/locations/nearby?latitude&longitude&rangeInMetres	—
Distance from search center	✅	SimplifiedBreweryDto.DistanceMetres, computed server-side via geography::STDistance	—
One-line note / tagline per brewery	❌	none	SimplifiedBreweryDto (used by both /locations and /locations/nearby) has no description-like field. List and map-popup text use filler. Needs either a short tagline field or a truncated Description added to that DTO.
User's current location	✅	Browser Geolocation API	—
Fallback region (before permission granted / on denial)	⚠️	Falls back to the featured brewery's own coordinates as a proxy center	Works, but isn't a deliberate "default region." A real deployment likely wants a configured default (e.g. per-tenant HQ city) rather than borrowing the featured brewery's location.
Manual location entry ("Change location")	❌	Re-requests browser geolocation only	No geocoding/place-search endpoint exists to resolve a typed address or city name to coordinates.
Search radius	✅	Client-side state (10–150 km slider), passed straight through to rangeInMetres	—

4. Recently added

Field	Status	Current source	Gap
Newest breweries, name/city/description	✅	GET /api/brewery (already sorted newest-first)	—

No gaps — this section is fully real.

5. Directory CTA

Field	Status	Current source	Gap
Total partner brewery count	❌	Filler number (128)	No lightweight count endpoint. Needs something like GET /api/brewery/count rather than fetching the full unbounded list just to measure it.
Filter by country / region / beer style	❌	Copy only — not implemented	This is CTA copy describing the destination directory page's future capability, not a data need of this page itself. Tracked here because it implies the directory page will eventually need country/region/style filter params.

Cross-cutting: the Beers feature is empty

Features.Beers (backend) has a .csproj and nothing else — no query handlers, no controller, no DTOs. BeerPost exists as a domain entity (with BrewedById linking to BreweryPost) but nothing exposes it over the API. This blocks:

• "Beers listed" count on the featured card.
• "House style" (would likely aggregate from a brewery's beers' BeerStyle).
• Any future beer-style filter on the directory.

Summary of backend work to fully close the gaps

1. IsFeatured flag (or equivalent rotation query) on BreweryPost.
2. FoundedYear (or similar) column on BreweryPost.
3. A short tagline/note field on BreweryPost, surfaced through SimplifiedBreweryDto.
4. Stand up Features.Beers — at minimum a query to count beers per brewery and read their styles.
5. GET /api/brewery/count.
6. A geocoding/place-search endpoint for manual location entry.
7. (Product decision, not code) a configured default region to fall back to instead of the featured brewery's coordinates.
