Posthook + Next.js + AI

Schedule Delayed Tasks in Next.js Without Cron, Queues, or Workflow Engines

Posthook gives your Next.js app durable per-event timers. Schedule a reminder, expiration, or follow-up with one API call — your route handler runs when the time comes.

Webhook handlers

app/api/webhooks/remind/route.ts

One route per hook type. Each handler verifies the HMAC signature, checks task state, and acts or no-ops.

Task state machine

lib/tasks.ts

Schedule-first ordering, conditional updates, and epoch-based snooze.
