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.

The project overview


Following Agile methodologies, let's write two user stories that describe the functionality of our project. User stories shouldn't be comprehensive documents describing the entire set of features of an application; rather, small cards are perfect for not only describing what the user is trying to do, but also why. Also, we should do this without trying to design the whole system up front or delving too deep into implementation details.

First, we need a story about seeing the different journey types from which our users can select:

As a

traveler

I want

to see the different types of journeys I can get recommendations for

So that

I can decide what kind of evening to take my partner on

Secondly, we need a story about providing random recommendations for a selected journey type:

As a

traveler

I want

to see a random recommendation for my selected journey type

So that

I know where to go and what the evening will entail

These two stories represent the two...
