Router, outbox & delivery worker

Generated from pattern-library/registry.json — do not edit by hand; change the registry and run bun run patterns:build.

Index card — the docs below are the canonical explanation; deep-tier pattern pages additionally carry invariants and emulation notes.

Category: Notifications · Tier: light · Maturity: proven (verified 2026-08-20 @ 1a130d67) · Risk: low — internal queue/dispatch, no direct external call from the router itself

sendNotification() writes an in-app record, evaluates the settings matrix per channel, then queues outbox rows delivered by an in-process worker on containers or a cron sweep on Vercel.

When to use: Use as the single entry point for sending any multi-channel notification instead of calling a channel provider directly.
