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 RESTful API with revel.go

revel.go is also a fully-fledged web framework like Python's Django. It is older than Gin and is termed as a highly productive web framework. It is an asynchronous, modular, and stateless framework. Unlike the go-restful and Gin frameworks where we created the project ourselves, Revel generates a scaffold for working directly:

  1. Install revel.go using the following command:
go get github.com/revel/revel  
  1. In order to run the scaffold tool, we should install one more supplementary package:
go get github.com/revel/cmd/revel

Make sure that $GOPATH/bin is in your PATH variable. Some external packages install the binary in the $GOPATH/bin directory. If it is in the path, we can access the executables system wide. Here, Revel installs a binary called revel.

  1. On Ubuntu or Mac OS X, you can make sure to point Go binaries to the system path using...
