Go in Action, Second Edition

Go in Action, Second Edition is a 384-page guide to modern Go development, aimed at professional developers with experience in at least one object-oriented language. Its coverage spans generics, error handling, testing, concurrency, project organization, production architecture, and AI-focused examples.

At a glance

Covers generics, error handling, unit testing, benchmarking, profiling, and built-in fuzz testing.
Uses Go Modules and workspaces for larger projects rather than relying on GOPATH-era material.
Explores concurrency through a practical RSS reader and includes structured logging with log/slog.
Introduces production-oriented architecture concepts including dependency inversion, domain-driven design, and hexagonal architecture.
Two appendices cover vector search and LLM-powered summarization, with examples involving Qdrant, Ollama, and LangChain for Go.
The listing says examples require Go 1.25 or later.

The stated intended reader is experienced in another object-oriented language, giving buyers a clear transition-focused audience.

Cons

Examples require Go 1.25 or later, which may limit usefulness for readers working with older Go toolchains.
