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.

Summary

We started this chapter with understanding client software: how a software client works and how we can create a few. We saw the basics of writing a command-line application. cli is a third-party package that allows us to create beautiful command-line applications. After installing it, we learned how to collect command-line arguments through the tool. We also explored commands and flags in our CLI application. Next, we looked into grequests, a package similar to Python requests that's used to make API requests from Go code. We learned how to make GET, POST, and other requests from the client programs. We looked at a fresh package called cobra for creating commands/sub-commands.

Then, we explored the GitHub API and how to fetch details about repositories. With the knowledge of both concepts, we developed a client that lists the repositories for a given user and also...
