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.

Summary


In this chapter, we exposed the data for our social polling solution through a highly scalable RESTful API and built a simple website that consumes the API to provide an intuitive way for users to interact with it. The website consists of static content only, with no server-side processing (since the API does the heavy lifting for us). This allows us to host the website very cheaply on static hosting sites, such as bitballoon.com, or distribute the files to content delivery networks.

Within our API service, we learned how to share data between handlers without breaking or obfuscating the handler pattern from the standard library. We also saw how writing wrapped handler functions allows us to build a pipeline of functionality in a very simple and intuitive way.

We wrote some basic encoding and decoding functions that –while only simply wrapping their counterparts from the encoding/json package for now –could be improved later to support a range of different data representations without...
