Build a powerful notification system with Next.js and Knock

This post details Vercel's implementation of a new notification system using Knock. It covers the selection of Knock for its iteration speed, reliability, and observability, highlighting its primitives for notification preferences, real-time feeds, and batching. The post showcases the integration of Knock's React library for building custom notification components and the use of Knock's API for managing user preferences without redeploying infrastructure. It also introduces new notification types for deployment failures and batched domain misconfigurations.
