To set up a type-safe job queue in TypeScript, define a PayloadMap mapping job types to payload shapes, implement corresponding JobHandlers, and initialize a singleton queue instance. This enforces typed payloads and guarantees handler coverage to reduce runtime errors.

Yes, you can use this typed job queue with both PostgreSQL and Redis backends. The core patterns support reliable enqueue and dequeue behavior, batching, dependencies, and retries across both supported storage backends for server-side applications.

A PayloadMap in TypeScript job queue orchestration is a mapping of job types to their specific payload shapes. It guarantees that every job type has a corresponding handler with the correct typings, enforcing safe handler wiring and reducing runtime errors.

You handle retries and dead-letter routing by configuring the queue processing workflow with explicit retry logic. The core patterns support optional advanced scenarios including transactional job creation in PostgreSQL and dead-letter routing for failed jobs.

You should use a singleton queue instance to share a single queue connection across your application. This initialization pattern avoids creating multiple connection pools, ensuring consistent and efficient job processing across PostgreSQL or Redis backends.
