Your First Temporal Workflow in Go: DI, Idempotency, and the Worker Pattern

Your First Temporal Workflow in Go#

This article establishes the patterns used throughout the Temporal series: dependency injection for testable activities, idempotency for safe retries, and a clean worker binary. Every subsequent article builds on these foundations.

All code lives in the companion repo at github.com/statherm/temporal-examples. For background, see Introduction to Temporal and Namespaces and Task Queues.

Project Structure#

The companion repo organizes code by domain:

temporal-examples/
 cmd/worker/main.go # Worker binary
 cmd/starter/main.go # Workflow starter CLI
 internal/container/
 activities.go # Activity implementations with DI
 workflow.go # Workflow definitions
 types.go # Interfaces and types
 Makefile

Workflows and Activities#

A workflow is a deterministic function that orchestrates work. It takes workflow.Context, must not perform side effects, and dispatches work through activities. Activities use standard context.Context and perform real I/O:

Building a Temporal Worker Bridge#

The architecture article evaluated three cross-cluster communication patterns and identified the worker bridge as the best fit for most open-source Temporal deployments. This article builds the bridge.
