Overview of this book

Go is the language of the Internet age, and the latest version of Go comes with major architectural changes. Implementation of the language, runtime, and libraries has changed significantly. The compiler and runtime are now written entirely in Go. The garbage collector is now concurrent and provides dramatically lower pause times by running in parallel with other Go routines when possible. This book will show you how to leverage all the latest features and much more. This book shows you how to build powerful systems and drops you into real-world situations. You will learn to develop high quality command-line tools that utilize the powerful shell capabilities and perform well using Go's in-built concurrency mechanisms. Scale, performance, and high availability lie at the heart of our projects, and the lessons learned throughout this book will arm you with everything you need to build world-class solutions. You will get a feel for app deployment using Docker and Google App Engine. Each project could form the basis of a start-up, which means they are directly applicable to modern software markets.

Composing all five programs


Now that we have completed all five programs, it's time to put them all together so that we can use our tool to find an available domain name for our chat application. The simplest way to do this is to use the technique we have been using throughout this chapter: using pipes in a terminal to connect the output and input.

In the terminal, navigate to the parent folder of the five programs and run the following single line of code:

./synonyms/synonyms | ./sprinkle/sprinkle | ./coolify/coolify |  ./domainify/domainify | ./available/available

Once the programs are running, type in a starting word and see how it generates suggestions before checking their availability.

For example, typing in chat might cause the programs to take the following actions:

  1. The word chat goes into synonyms, which results in a series of synonyms:

    • confab

    • confabulation

    • schmooze

  2. The synonyms flow into sprinkle; here they are augmented with web-friendly prefixes and suffixes, such as the following:

    • confabapp...
