For this book, you should have some basic knowledge of the Go programming language (if you're still looking to get started with Go, we can recommend the book Learning Go Programming by Vladimir Vivien, also published by Packt). To run the code examples provided in this book, you will also need a working Go SDK on your local machine (Go 1.7 or newer). Head to https://golang.org/dl/ for download and installation instructions.
For many of the practical examples in the book, you will need a working Docker installation (although previous experience in working with Docker is not required). Take a look at https://www.docker.com/community-edition for download and installation instructions.
For working with React in Chapter 5, Building a Frontend With React, you will also need some basic knowledge in JavaScript programming and a working Node.JS installation on your local machine. You can download the current release of Node.JS from https://nodejs.org/en/#download.
