Golang was conceived and built at Google around 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. The objective was to build a pragmatic programming language to handle large code bases, complex multi-threading scenarios, and multi-core processors. Version 1.0 went out in March 2012, and since then, the language has grown in leaps and bounds in terms of popularity. Developers like me love its simplicity, expressiveness, explicit nature, and awesome community.

Having built a few production-grade applications in Go over the past few years, I have tried to distill my learning from a hands-on architect perspective in this book. Primarily, the book is a broad overview of the Go ecosystem, but at a few junctures, we deep dive and write code to demonstrate the theory. Finally, we build a non-trivial e-commerce application using the learned constructs!
