The runtime has always read GEOLITE2_DIR, but the variable was absent from the compose `environment:` whitelist, from both env examples, and from the docs. A variable that is not on that whitelist never reaches the container even when the operator's `.env` sets it, so the override existed in code and was unreachable from the documented path. Put it on the whitelist, document it in both examples and the manifest, and add `docs/self-hosting/geolite2.md`: fetch the databases with a free MaxMind account, mount the directory read-only, point the variable at it. The compose file carries the bind-mount line commented out beside the app service. The admin notification told the reader to set MAXMIND_LICENSE_KEY in this repository's Actions secrets — something nobody running the published image can do, about a fallback that sends their sign-in addresses to a third party. It now names the mount, names the online provider it is actually querying, and links the runbook. Six locales. It also no longer claims the carrier column stays empty; the online tier has filled the carrier from the ISP field since v1.25.8. A blank GEOLITE2_DIR now resolves to the default instead of the process working directory: compose substitutes an unset variable to the empty string, which is not nullish. Refs #659
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 renamedmiddleware). 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 inapiHandler. Seeapp/README.md.lib/— the server/runtime toolkit:apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. Seelib/README.md.components/— React components (shadcn/ui new-york, kebab-case files). Seecomponents/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 byprisma 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.
