API patterns and service integrations — SvelteKit-native REST + server actions, plus an in-app analytics collector, console-based error handling, Resend email, and a custom cron-driven job runner. See the api-design skill for contract patterns.
Stack
| Concern | Technology | Provider |
|---|---|---|
| API style | REST + server actions | SvelteKit (framework-native) |
| Analytics | In-app collector | $lib/server/analytics/ + /api/analytics/* (server-side, consent-gated) |
| Errors | handleError hook |
Console-only (src/hooks.server.ts); no external provider wired |
| SMTP/API | Resend |
Background jobs — use when a task takes 5+ seconds, needs cron, or needs retries:
| Complexity | Technology | Use case |
|---|---|---|
| Default | Server actions | Fast, no deps |
| Scheduled / async | Custom job runner | $lib/server/jobs (runJob) via Vercel-cron /api/cron/[job] |
Known limitations
- Server actions: platform-bound max execution (10s Vercel free, 60s Pro); no native retry or scheduling.
- Errors: no external error provider (Sentry, etc.) wired —
handleErroronly logs structured JSON to the console.
