Build systems with Go

Why this book?

Years have passed by and Go is no longer the new kid on the block, it has already become a mature language surrounded by a rich ecosystem of libraries, projects, and tools. Talking about Go is no longer talking about that fancy language that makes your life easier. Go is the gravity centre of a continuously growing ecosystem of amazing solutions maintained by a devoted community of developers.

Go was originally designed to simplify the building of complex systems. However, when a developer decides to learn Go most of the learning resources simply explain the language. This book goes one step further by exploring tools, libraries, and projects from the Go ecosystem you can use to build ready-for-production systems. Everything a gopher must know in a single book.

Who sould read this book?

This book is oriented to new Go adopters and developers with programming experience in other languages. The first part of this book covers the Go language from its basics to more advanced concepts.

However, if you have some experience you can start with the second part and revisit any basic concept if needed. Or you can simply go and check those chapters you find the most relevant.
