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.

Summary

Throughout this chapter, we have learned about middleware and how to implement and use middleware within the Echo framework. Middleware serves as a means to minimize duplication within your handler code by abstracting common functionality out of the handlers.

This means that your web application can remain ignorant to the functionality that the middleware provides. This chapter also outlines a variety of middleware functions that come with the Echo framework that have been contributed to by the community.

The next chapter will dive into details mentioned within this chapter of request data binding. We will also cover the echo.Context primitive, which allows us to pass application context from the Echo framework...
