The Echo framework provides three mechanisms for inserting middleware into your request-processing pipeline. The Echo instance's Use(MiddlewareFunc) helper method is the most common way to add normal post-routing middleware. As you may recall, for flexibility we showed you how to use the Group(string) Echo method to organize routes. The Use(MiddlewareFunc) helper method is also available on Group instances so that you can apply middleware functions only to particular groupings of routes as well. Use tells the Echo instance, or grouping instance, that we wish to insert the middleware specified as a parameter into our middleware chain. It should be made clear that the order of your Use calls is very important. The order of the middleware insertion stipulates the order in which the middleware chain will be performed. For example, you might want two middleware...

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.
