Temporal Workflows in Practice

What happens when a background job crashes halfway through-or an external service succeeds but your application never receives the response? Building reliable software means planning for failures, not just hoping they won't happen.

Temporal Workflows in Practice takes the mystery out of durable execution with clear explanations and a progressive, hands-on TypeScript project. No prior Temporal experience is needed. You'll start with the fundamentals and gradually build workflows that recover from interruptions, coordinate services, and handle long-running tasks.

Follow a realistic order-processing application as it evolves from a simple workflow into a dependable distributed system. Along the way, you'll troubleshoot failures, inspect execution histories, and learn why each design decision matters. Every successful test-and every corrected mistake-builds practical confidence.

• Step-by-step learning: Clear explanations and practical examples using the official Temporal TypeScript SDK.

• Hands-on development: One evolving project connecting Workflows, Activities, Workers, and Clients.

• Real-world reliability: Practical failure-recovery, approval, scheduling, and microservice scenarios.

• Production-focused guidance: Testing, deployment, monitoring, and troubleshooting techniques.

• Design deterministic workflows and understand execution replay.

• Configure retries, timeouts, heartbeats, and idempotent operations.

• Build durable timers, human approvals, and scheduled background jobs.

• Coordinate microservices using saga patterns and compensating transactions.

• Test, debug, secure, and monitor production workflows.

• Apply durable orchestration to AI model calls and tool execution.

This book is ideal for developers learning Temporal, backend and TypeScript programmers, software engineers, and platform professionals who want to build more dependable applications.

You don't need previous experience with Temporal or workflow orchestration. Basic familiarity with programming, asynchronous operations, APIs, and databases is recommended. The progressive examples help you develop your skills one practical step at a time.
