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.

What are microservices?

What are microservices? This is the question the enterprise world is asking the computing world. The sustainability of a product depends on how easily modifiable it is. Huge products should retire at some point in time if they cannot be maintained properly. The microservice architecture replaces the traditional monolith with granular services that talk to each other in some kind of agreement.

Microservices bring the following benefits to the table:

  • Small teams can iterate in parallel by working on a small set of features.
  • Adaptability is easy for new developers.
  • They allow Continuous Integration (CI) and Continuous Delivery (CD) for individual components of a system.
  • They offer easily replaceable software with a loosely coupled architecture.
  • The architecture is not coupled to a specific technology

In a monolithic application (traditional application)...
