Inngest + Next.js Patterns

Templates and conventions for building event-driven, durable background work on Inngest from a Next.js App Router project. The skill enforces the conventions Inngest's own docs use (decentralized eventType() schemas, kebab-case stable function IDs, idempotent steps) so that retries, replays, and concurrency controls actually do what they advertise.

When to Apply

Read this skill when you are:

• Setting up Inngest in a Next.js app for the first time (client + route handler + first function)
• Adding a new background job, webhook handler, or scheduled task to a Next.js app
• Defining a new domain event that other functions will trigger on
• Orchestrating multi-step work that must survive process restarts (durable workflows, sagas)
• Reviewing existing Inngest code for event naming, step idempotency, or stable function IDs
• Migrating from setTimeout / a queue library / a cron service to Inngest's durable execution model
