Network Programming with Go
Network Programming with Go teaches you how to write clean, secure network software with the programming language designed to make it seem easy. Build simple, reliable, network software Combining the best parts of many other programming languages, Go is fast, scalable, and designed for high-performance networking and multiprocessing. In other words, it’s perfect for network programming. Network Programming with Go will help you leverage Go to write secure, readable, production-ready network code. In the early chapters, you’ll learn the basics of networking and traffic routing. Then you’ll put that knowledge to use as the book guides you through writing programs that communicate using TCP, UDP, and Unix sockets to ensure reliable data transmission. As you progress, you’ll explore higher-level network protocols like HTTP and HTTP/2 and build applications that securely interact with servers, clients, and APIs over a network using TLS. You'll also learn: Internet Protocol basics, such as the structure of IPv4 and IPv6, multicasting, DNS, and network address translation Methods of ensuring reliability in socket-level communications Ways to use handlers, middleware, and multiplexers to build capable HTTP applications with minimal code Tools for incorporating authentication and encryption into your applications using TLS Methods to serialize data for storage or transmission in Go-friendly formats like JSON, Gob, XML, and protocol buffers Ways of instrumenting your code to provide metrics about requests, errors, and more Approaches for setting up your application to run in the cloud (and reasons why you might want to) Network Programming with Go is all you’ll need to take advantage of Go’s built-in concurrency, rapid compiling, and rich standard library. Covers Go 1.15 (Backward compatible with Go 1.12 and higher)

Explore Go testing techniques and leverage TDD to deliver and maintain microservices architecture, including contract, end-to-end, and unit testing Purchase of the print or Kindle book includes a free PDF eBook Key Features Write Go test suites using popular mocking and testing frameworks Leverage TDD to implement testing at all levels of web applications and microservices architecture Master the art of writing tests that cover edge cases and concurrent code Book Description Experienced developers understand the importance of designing a comprehensive testing strategy to ensure efficient shipping and maintaining services in production. This book shows you how to utilize test-driven development (TDD), a widely adopted industry practice, for testing your Go apps at different levels. You'll also explore challenges faced in testing concurrent code, and learn how to leverage generics and write fuzz tests. The book begins by teaching you how to use TDD to tackle various problems, from simple mathematical functions to web apps. You'll then learn how to structure and run your unit tests using Go's standard testing library, and explore two popular testing frameworks, Testify and Ginkgo. You'll also implement test suites using table-driven testing, a popular Go technique. As you advance, you'll write and run behavior-driven development (BDD) tests using Ginkgo and Godog. Finally, you'll explore the tricky aspects of implementing and testing TDD in production, such as refactoring your code and testing microservices architecture with contract testing implemented with Pact. All these techniques will be demonstrated using an example REST API, as well as smaller bespoke code examples. By the end of this book, you'll have learned how to design and implement a comprehensive testing strategy for your Go applications and microservices architecture. What you will learn Create practical Go unit tests using mocks and assertions with Testify Build table-driven test suites for HTTP web applications Write BDD-style tests using the Ginkgo testing framework Use the Godog testing framework to reliably test web applications Verify microservices architecture using Pact contract testing Develop tests that cover edge cases using property testing and fuzzing Who this book is for If you are an intermediate-level developer or software testing professional who knows Go fundamentals and is looking to deliver projects with Go, then this book is for you. Knowledge of Go syntax, structs, functions, and interfaces will help you get the most out of this book.
Go 언어를 활용한 네트워크 프로그래밍
간결하며 신뢰할 수 있는 네트워크 소프트웨어! 주요 프로그래밍 언어에서 장점만 조합하여 만든 Go 언어는 빠른 속도와 확장성을 자랑하며, 네트워크와 멀티 프로세스 처리에 고성능을 내도록 설계되었습니다. 즉, 네트워크 프로그래밍에 최적화된 언어입니다. 《Go 언어를 활용한 네트워크 프로그래밍》은 Go 언어를 사용하여 보안에 강하며, 신뢰할 수 있고, 가독성이 좋은, 그리고 실제 서비스에 사용할 수 있는 네트워크 코드를 작성할 수 있도록 도와줍니다. 전반부에서는 네트워크와 트래픽 라우팅에 대한 기본 지식을 배우며, 후반부에서는 배운 지식을 활용하여 TCP와 UDP, 유닉스 소켓을 사용하는, 신뢰성 있는 데이터 통신 프로그램을 작성합니다. HTTP나 HTTP/2와 같은 상위 계층의 네트워크 프로토콜을 점진적으로 경험하고, TLS를 사용하여 네트워크를 통해 서버와 클라이언트, 서드파티 API 사이에서 안전하게 통신하는 애플리케이션을 구현합니다. 한마디로 이 책은 Go 언어에 내재된 병렬성과 빠른 컴파일 속도, 그리고 풍부한 표준 라이브러리를 활용할 수 있는 다양한 방법을 살펴봅니다. 주요 내용 ■ IPv4, IPv6의 구조, 멀티캐스트, DNS, 그리고 네트워크 주소 해석과 같은 인터넷 프로토콜의 기초 ■ 소켓 레벨 통신에서 신뢰성을 확보하는 방법 ■ 핸들러와 미들웨어, 멀티플렉서를 사용하여 최소한의 코드로 HTTP 애플리케이션을 작성하는 방법 ■ TLS를 사용하여 애플리케이션에 인증과 암호화를 통합하는 도구 사용법 ■ Go 언어가 쉽게 처리할 수 있는 데이터 포맷인 JSON이나 Gob, XML, 프로토콜 버퍼를 활용하여 데이터를 직렬화하고 저장하거나 전송하는 방법 ■ 요청이나 에러 등의 정보를 포함하는 메트릭스를 만들기 위한 코드 계측 방법 ■ 애플리케이션을 클라우드에 배포하는 방법과 시점
