Marc-André BombeckandClaude Opus 4.7 ca1c52ffcb feat(avatar): self-hosted avatar storage replacing the Gravatar leak
The previous /me payload carried a gravatarUrl built from
SHA-256(email) and pointed every authenticated page-load at
www.gravatar.com — Automattic could correlate the digest against
its known-email table on each request. This release moves the
avatar in-house: the user uploads through POST /api/user/avatar
(multipart, JPEG/PNG/WebP, 2 MiB / 2048×2048 max), the bytes ride
on the User row alongside a content-type and updatedAt timestamp,
and GET /api/user/avatar/{id} serves them from same-origin with
the cache-busting timestamp on the profile response.

The image-header parsing is hand-rolled in src/lib/avatar.ts so
the standalone image does not gain a native dep just to read width
and height. Validation rejects oversize / wrong content-type at
the multipart parse boundary; DELETE clears the row. The bytes
ride pg_dump alongside the rest of the row so the existing weekly
encrypted backup path already covers them.

The sidebar, the coach panel, the use-auth hook, and the disable-
coach card stop reading gravatarUrl; src/lib/gravatar.ts retires.

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.
