Go Cookbook

Bridge the gap between basic understanding of Go and use of its advanced featuresAbout This BookDiscover a number of recipes and approaches to develop modern back-end applicationsPut to use the best practices to combine the recipes for sophisticated parallel toolsThis book is based on Go 1.8, which is the latest versionWho This Book Is ForThis book is for web developers, programmers, and enterprise developers. Basic knowledge of the Go language is assumed. Experience with back-end application development is not necessary, but may help understand the motivation behind some of the recipes.What You Will LearnTest your application using advanced testing methodologiesDevelop an awareness of application structures, interface design, and toolingCreate strategies for third-party packages, dependencies, and vendoringGet to know tricks on treating data such as collectionsHandle errors and cleanly pass them along to calling functionsWrap dependencies in interfaces for ease of portability and testingExplore reactive programming design patterns in GoIn DetailGo (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library.This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers.The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.Style and approachThis guide is a handy reference for developers to quickly look up Go development patterns. It is a companion to other resources and a reference that will be useful long after reading it through the first time. Each recipe includes working, simple, and tested code that can be used as a reference or foundation for your own applications.
