A hands-on guide for Java/Spring Boot developers learning Go by building a REST API for a bookmarking application. Covers project setup, Gin web framework, configuration management with Viper, structured logging with Zap, PostgreSQL access via pgx, database migrations with golang-migrate, code refactoring using Go structs and interfaces, and Dockerizing the app. Includes a comparison of Java/Spring Boot vs Go tradeoffs around verbosity, resource usage, and developer productivity.
