Mastering Go - Fourth Edition

Dive into the core of Go programming and cover advanced topics like generics, concurrency, web services, and cutting-edge testing techniques in this comprehensive fourth edition.Key FeaturesFully updated with coverage of web services, TCP/IP, REST APIs, Go Generics, and Fuzzy TestingApply your new knowledge to real-world exercises, building high-performance servers and robust command-line utilities, to deepen your learningGain clarity on what makes Go different, understand its nuances and features for smoother Go developmentBook DescriptionMastering Go, now in its fourth edition, remains the go-to resource for real-world Go development. This comprehensive guide delves into advanced Go concepts, including RESTful servers, and Go memory management. This edition brings new chapters on Go Generics and fuzzy Testing, and an enriched exploration of efficiency and performance. As you work your way through the chapters, you will gain confidence and a deep understanding of advanced Go topics, including concurrency and the operation of the Garbage Collector, using Go with Docker, writing powerful command-line utilities, working with JavaScript Object Notation (JSON) data, and interacting with databases.You will be engaged in real-world exercises, build network servers, and develop robust command-line utilities. With in-depth chapters on RESTful services, the WebSocket protocol, and Go internals, you are going to master Go's nuances, optimization, and observability. You will also elevate your skills in efficiency, performance, and advanced testing.With the help of Mastering Go, you will become an expert Go programmer by building Go systems and implementing advanced Go techniques in your projects.What you will learnLearn Go data types, error handling, constants, pointers, and array and slice manipulations through practical exercisesCreate generic functions, define data types, explore constraints, and grasp interfaces and reflectionsGrasp advanced concepts like packages, modules, functions, and database interactionCreate concurrent RESTful servers, and build TCP/IP clients and serversLearn testing, profiling, and efficient coding for high-performance applicationsDevelop an SQLite package, explore Docker integration, and embrace workspacesWho this book is forMastering Go is written primarily for Go programmers who have some experience with the language and want to become expert practitioners. You will need to know the basics of computer programming before you get started with this book, but beyond that, anyone can sink their teeth into it.Table of ContentsA Quick Introduction to GoBasic Go Data TypesComposite Data TypesGo GenericsReflection and InterfacesGo Packages and FunctionsTelling a UNIX System What to DoGo ConcurrencyBuilding Web ServicesWorking with TCP/IP and WebSocketWorking with REST APIsCode Testing and ProfilingFuzz Testing and ObservabilityEfficiency and PerformanceChanges in Recent Go VersionsAppendix
