Build Systems With Go: Everything a Gopher must know

Second edition (v0.2.0) with revisited content, enhanced explanations, a new chapter about Cgo, and more awesome gophers.

Because
to build a system you need more than a collection of loops, this book
offers the reader a complete explanation of the most useful aspects of
the Go language, and how to use them with existing tools from the Go
ecosystem. Do not stay in the basics, move forward and learn how to
build systems with restful APIs, gRPC messaging, powerful loggers,
middleware, SQL/noSQL databases, data streaming, and more. A book
written for new adopters and experienced developers.
