In this chapter, we will discuss routing of the application. For creating an API, the first step is to define routes. So, to define routes, we need to figure out available constructs in Go. We begin with the basic internal routing mechanism in Go. Then, we see how to create a custom Multiplexer. Since ServeMux's capabilities are very limited, we will explore a few other frameworks built to serve this purpose. This chapter also includes creating routes using third-party libraries such as httprouter
and Gorilla Mux
. We are going to build a URL-shortening API throughout this book. In this chapter, we define routes for the API. Then, we discuss topics like SQL injection of an URL. A web framework allows the developer to create a route as the first step and then attach handlers to it. Those handlers hold the business logic of the application. The crux of this chapter is teaching you how to create HTTP routers in Go using Gorilla Mux
. We also discuss...

Overview of this book
REST is an architectural style that tackles the challenges of building scalable web services and in today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs. The depth, breadth, and ease of use of Go, makes it a breeze for developers to work with it to build robust Web APIs. This book takes you through the design of RESTful web services and leverages a framework like Gin
to implement these services.
The book starts with a brief introduction to REST API development and how it transformed the modern web. You will learn how to handle routing and authentication of web services along with working with middleware for internal service. The book explains how to use Go frameworks to build RESTful web services and work with MongoDB to create REST API. You will learn how to integrate Postgres SQL and JSON with a Go web service and build a client library in Go for consuming REST API. You will learn how to scale APIs using the microservice architecture and deploy the REST APIs using Nginx as a proxy server. Finally you will learn how to metricize a REST API using an API Gateway.
By the end of the book you will be proficient in building RESTful APIs in Go.
