Echo Quick Start Guide

By: Ben Huson

Overview of this book

Echo is a leading framework for creating web applications with the Go language.  This book will show you how to develop scalable real-world web apps, RESTful services, and backend systems with Echo.  After a thorough understanding of the basics, you'll be introduced to all the concepts for a building real-world web system with Echo. You will start with the the Go HTTP standard library, and setting up your work environment. You will move on to Echo handlers, group routing, data binding, and middleware processing. After that, you will learn how to test your Go application and use templates.  By the end of this book you will be able to build your very own high performance apps using Echo. A Quick Start Guide is a focussed, shorter title which provides a faster paced introduction to a technology. They are for people who don’t need all the detail at this point in their learning curve. The presentation has been streamlined to concentrate on the things you really need to know, rather than everything.

Who this book is for

Software developers who are fairly new to Go and are looking to employ a high-performance web application or backend API will be most rewarded by this book. Developers who have a performance requirement for their APIs and developers who have some Go experience, as well as experience with web application frameworks in general but not with Echo, will also benefit.

We assume that the reader will be well-versed in web technologies, with a basic understanding of the HTTP protocol and REST API design concepts. We further assume that the reader will have worked with another backend web application framework before and understands the processing pipelines that are common in web frameworks.
