inngest-middleware

Share stateful clients like database connections across Inngest durable functions by implementing dependency injection through a standardized middleware lifecycle, ensuring consistent behavior without code duplication.

Add Sentry error tracking to TypeScript durable functions by integrating the optional @inngest/middleware-sentry package, which executes custom observability logic at specific points in the function execution lifecycle.

Standardize observability in distributed event-driven workflows by using middleware lifecycle hooks to execute custom tracking logic, ensuring consistent metrics and error reporting across all functions without code duplication.

Encrypt sensitive payload data in Inngest event-sending workflows by integrating the optional @inngest/middleware-encryption package into your client's middleware configuration.

Yes, implementing cross-cutting concerns like dependency injection and data encryption through the middleware lifecycle requires integration with the Inngest v4 TypeScript SDK.

Use middleware to manage cross-cutting concerns in durable functions when you need to consistently apply logic like observability, error tracking, or circuit breakers across distributed event-driven workflows without duplicating code.
