Marc-André Bombeck 31c35baec2 feat: hydration logging and daily goal ring
Add a WATER_INTAKE measurement type and a per-user daily goal so the
Insights overview can track water intake against a goal ring. Logging
rides the existing measurements create path (type WATER_INTAKE, unit ml,
summed cumulatively); GET/PATCH /api/hydration read the day total and own
the goal. The goal-ring math (empty / partial / met / exceeded) lives in
a pure helper, free of Prisma and React, and is unit-tested in isolation.

Wire the new type through the measurement enum, value ranges, cumulative
HealthKit handling, categories, display transform, list metadata, record
direction, and the chartable-token allowlist. The HealthKit DietaryWater
import stays on the nutrition hold, so the type carries no import mapping
by design.

Document GET/PATCH /api/hydration in the OpenAPI contract.

src/

Application source. HealthLog is a Next.js 16 App Router project (output: "standalone", React 19, TypeScript strict). The path alias @/* resolves to this directory. Everything a request touches lives under here; the layout below follows the request flow rather than alphabetical order.

Request flow

client → src/proxy.ts → src/app/<route>/route.ts → src/lib/api-handler.ts → handler body → src/lib/api-response.ts → client
  • proxy.ts — the HTTP edge (Next.js 16's renamed middleware). Public-path allowlist, demo-mode mutation block, server-side onboarding redirect, worker-only refusal, x-request-id + CSP nonce generation, every security header.
  • app/ — App Router pages (RSC by default) and API routes. Every API route wraps its handler in apiHandler. See app/README.md.
  • lib/ — the server/runtime toolkit: apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. See lib/README.md.
  • components/ — React components (shadcn/ui new-york, kebab-case files). See components/README.md.

Other directories

  • hooks/ — shared React hooks (use- prefix, kebab-case).
  • types/ — shared TypeScript declarations.
  • generated/prisma/ — the generated Prisma client (do not edit; regenerated by prisma generate). Imported as @/generated/prisma.
  • instrumentation.ts — Next.js startup hook; boots the pg-boss worker registry and boot-time backfill queues.
  • __tests__/ — cross-cutting unit tests; most tests live in __tests__/ folders next to the code they cover.

Conventions

See ../CLAUDE.md for the full set. The load-bearing ones: RSC by default ("use client" only when a hook/state/browser API needs it); every API route wraps apiHandler and parses its body with Zod safeParse; userId is always narrowed from session or Bearer, never accepted as a body field; TanStack Query keys come only from src/lib/query-keys/; outbound HTTP goes through src/lib/safe-fetch.ts.
