Hands-On RESTful Web Services with Go - Second Edition

By: Naren Yellavula

Overview of this book

Building RESTful web services can be tough as there are countless standards and ways to develop API. In modern architectures such as microservices, RESTful APIs are common in communication, making idiomatic and scalable API development crucial. This book covers basic through to advanced API development concepts and supporting tools. You’ll start with an introduction to REST API development before moving on to building the essential blocks for working with Go. You’ll explore routers, middleware, and available open source web development solutions in Go to create robust APIs, and understand the application and database layers to build RESTful web services. You’ll learn various data formats like protocol buffers and JSON, and understand how to serve them over HTTP and gRPC. After covering advanced topics such as asynchronous API design and GraphQL for building scalable web services, you’ll discover how microservices can benefit from REST. You’ll also explore packaging artifacts in the form of containers and understand how to set up an ideal deployment ecosystem for web services. Finally, you’ll cover the provisioning of infrastructure using infrastructure as code (IaC) and secure your REST API. By the end of the book, you’ll have intermediate knowledge of web service development and be able to apply the skills you’ve learned in a practical way.

Building a Metro Rail API with go-restful

Let's use the knowledge of go-restful and SQLite3 we have gained and create an API for the Metro Rail project we talked about in the preceding section. The road map is as follows:

  1. Design a REST API document
  2. Create models for a database
  3. Implement the API logic

Let's understand each of them in detail.

Design specification

Before creating any API, we should know what the specifications of APIs are in the form of a document. We showed an example in Chapter 2, Handling Routing for our REST Services, where we showed the URL shortener API design document. Let's try to create one for this Metro Rail project. Take a look at the following table:
