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.

Summary


In this chapter, we first looked into what middleware is, exactly, including how middleware processes a request and response. We then explored middleware code with a few practical examples. After that, we saw how to chain our middleware by passing one middleware to another. Then, we used a package called Alice for intuitive chaining. We also took a look at the Gorilla handlers middleware for logging. Next, we learned what an RPC is and how an RPC server and client can be built. After that, we explained what a JSON RPC is, and we saw how one can create a JSON RPC using Gorilla toolkit. We introduced many third-party packages for middleware and RPC, with examples.

In the next chapter, we are going to explore few famous web frameworks those further simplify the REST API creation. They have batteries included by possessing inbuilt middleware and HTTP routers.
