The Go Programming Cookbook ensures Go programmers may confidently and effectively navigate the complex software development landscape. Both newcomers to the world of Go programming and seasoned professionals looking to sharpen their skills will find something of interest in this carefully written book.

This cookbook covers a wide range of topics, from the basics of Go syntax and core ideas to more advanced subjects like concurrency, networking, and microservices design. Building a Go development environment, learning the fundamentals of Go constructs, and mastering the art of Go Module dependency management are all covered in the first few chapters, which prepare readers for what's to come. To guarantee that readers can construct strong and maintainable programs, the next sections cover error handling, unit testing, and database interfaces. The book really comes into its own when it comes to its in-depth examination of network programming; it covers topics like building HTTP clients, implementing FTP and SSH clients, and using WebSockets for real-time communication.

To prepare developers to create safe, networked applications in a world where everything is always connected, it teaches them how to establish secure TLS/SSL communications, which is a fundamental component of security. In addition to providing practical solutions, the recipes educate readers on the concurrency model and design principles of Go, which helps them build an intuitive understanding of high-performance software development.

This book takes its time to go over every important aspect of backend programming, from the fundamentals to more advanced techniques, so that you can become experts in Go scripting and all the things Go can do. Quickly introducing readers to Go and its ecosystem, the book walks them through installing the language and creating a development environment with Visual Studio Code. Next, it takes a baby step into learning the basics of building web servers with the net/http package, going over topics like routing, handling various HTTP methods, and the structures of requests and responses. Path variables, regex-based routing, custom handlers, and middleware are some of the advanced routing topics covered, which uses the robust gorilla/mux package. After introducing session and cookie management, the book moves on to user authentication, covering topics such as OAuth2 integration, JWT for secure APIs, and more.

The book then teaches various aspects of database integration with GORM, covering topics such as connecting to SQL databases, performing CRUD operations, managing migrations, and handling transactions and concurrency control. The Gin framework for designing and implementing microservices, REST and gRPC for inter-service communication, and Kubernetes for containerizing applications are also covered in detail. Also covered is message brokering with Apache Kafka and NSQ for asynchronous systems, which guarantees resilient systems and efficient message delivery. Secure coding practices, HTTPS with crypto/tls, avoiding SQL injections and XSS attacks, and configuration management with Viper are also one of the main goal of the book.

Last but not least, the book covers testing and debugging with tools such as Delve, Testify, and GoMock. It then teaches readers through various deployment strategies, such as blue-green, canary, and rolling deployments with AWS CodeDeploy. Utilizing Go's robust features and clean scripting capabilities, this book provides you with the necessary knowledge and skills to develop secure, scalable, and resilient backend systems.
