Marc-André Bombeck fbdcb31202 feat(import): add CSV measurement import with per-row status and dry-run
A self-hoster migrating from a spreadsheet or a meter export overwhelmingly
has CSV, which neither the JSON nor the Apple Health import covers. Add
`POST /api/import/csv` reusing the existing write loop and rollup re-fold.

The documented header is `type,value,unit,measuredAt[,glucoseContext,notes,
externalId]`, order-independent. measuredAt must carry an explicit ISO-8601
offset — a row without one is skipped rather than guessed — and is bounded by
the shared entry-instant validator. Glucose accepts mmol/L (converted to
canonical mg/dL) and weight accepts lb (converted to kg); any other
non-canonical unit is skipped, never mis-stored. An optional externalId
column makes a re-upload idempotent; without it a re-upload duplicates.

The response carries a per-row status envelope so a 2000-row file with three
bad rows imports 1997 and names the three. `?dryRun=1` validates and previews
the outcome without writing. The parse, validation, and unit conversion live
in a pure module so they are unit-tested without a database.

Settings -> Export & Import gains a third CSV card mirroring the JSON and
Apple Health cards, with upload, paste, preview, and a downloadable example.
The new route is documented in the OpenAPI contract.

HealthLog API Spec

openapi.yaml is the canonical OpenAPI 3.1 description for the HealthLog Next.js API. It is the source of truth for the native iOS client's DTO codegen.

Preview locally

Open an interactive Redoc preview in your browser:

npx @redocly/cli preview docs/api/openapi.yaml

Generate static HTML for sharing:

npx @redocly/cli build-docs docs/api/openapi.yaml --output docs/api/index.html

Validate

npx @redocly/cli lint docs/api/openapi.yaml

The spec is expected to be lint-clean (errors = 0). Some warnings are intentional:

  • no-server-example.com — http://localhost:3000 is the dev server.
  • operation-2xx-response / operation-4xx-response — webhook + redirect endpoints intentionally omit one or the other.
  • no-unused-components — ReminderPhase is exposed for client codegen even though no path response references it directly.

Layout

  • info — title, version (mirrored from package.json), description.
  • servers — production https://healthlog.bombeck.io plus http://localhost:3000 for local development.
  • tags — domain groupings (Auth, Measurements, Medications, Mood, Dashboard, Insights, Achievements, DoctorReport, Integrations, User, Tokens, Notifications, Onboarding, Health, Settings, Analytics, Export, AuditLog, Feedback, BugReport, Monitoring, Webhooks, Ingest, Admin).
  • securitySchemes:
    • bearerAuth — long-lived hlk_* API tokens issued via POST /api/tokens. Required on /api/ingest/medication.
    • sessionCookie — HttpOnly healthlog_session cookie set by the password and passkey login flows. Used by the web app and any iOS client running inside a web view.
  • components.schemas — DTOs for all routes plus the underlying Prisma models (e.g. Measurement, Medication, MedicationIntakeEvent, MoodEntry, User, DashboardLayout, ApiEnvelope, ApiError).
  • paths — all routes from src/app/api/**/route.ts, including the /api/admin/* family which is tagged Admin and marked internal.

Conventions

  • Successful responses use the envelope { data, error: null }.
  • Error responses use the envelope { data: null, error: '<message>' }.
  • Pagination uses limit + offset query parameters and a meta: { total, limit, offset } block on the response.
  • All timestamps are ISO 8601 / RFC 3339 (format: date-time) in UTC.
  • IDs are CUIDs (opaque strings).

Updating the spec

When adding or changing routes:

  1. Update the relevant route handler under src/app/api/**/route.ts.
  2. Mirror the change in openapi.yaml. Keep operationId camelCase and stable — the iOS codegen keys off it.
  3. Run npx @redocly/cli lint docs/api/openapi.yaml and resolve all errors. Warnings are tolerated when documented above.
  4. Bump info.version if the change is breaking for clients.
