Go Cookbook: Build modular, readable, and testable applications in Go

• Discover a number of recipes and approaches to develop modern back-end applications
• Put to use the best practices to combine the recipes for sophisticated parallel tools
• This book is based on Go 1.8, which is the latest version

Go (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.

• Test your application using advanced testing methodologies
• Develop an awareness of application structures, interface design, and tooling
• Create strategies for third-party packages, dependencies, and vendoring
• Get to know tricks on treating data such as collections
• Handle errors and cleanly pass them along to calling functions
• Wrap dependencies in interfaces for ease of portability and testing
• Explore reactive programming design patterns in Go
