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.

RESTful API with gorilla/mux and MongoDB

In the previous chapters, we explored all the possible ways of building a RESTful API. We used basic HTTP routers, as well as many other web frameworks. However, to keep it simple, we can use gorilla/mux with mongo-driver for the MongoDB driver. In this section, we will build an end-to-end movie API while integrating the database and HTTP router. In the previous section, we learned how to create a new MongoDB document and retrieve it using mongo-driver. By consolidating our knowledge of HTTP routers and databases, we can create a movie API.

Let's create the plan so that we can create the API:

  1. Prepare structs to hold movie information and the database connection.
  2. Create a server for hosting the API.
  3. Prepare the routes for the API endpoints.
  4. Implement handlers for the routes.

We have to follow these steps to achieve our goal:

  1. Create...
