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.

Introducing mongo-driver, an official MongoDB driver for Go

mongo-driver is a rich MongoDB driver that allows developers to write applications that use MongoDB as the database. The Go application can talk easily with MongoDB for all its CRUD operations using the mongo driver. It is an open source implementation maintained by MongoDB and can be used and modified freely. We can think of it as a wrapper around the MongoDB API. Installing the package is similar to other go get commands. However, in this chapter, we'll introduce a new Go package tool called dep.

dep is a Go package installer tool similar to Python's pip or JavaScript's npm. Follow this web page to install the dep tool on various platforms: https://golang.github.io/dep/docs/installation.html.

Let's write a Go program that inserts The Dark Knight movie document into MongoDB. Follow these steps:
