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 an introduction to MongoDB and how it solves the problems of the modern web. MongoDB is a NoSQL database that is different from traditional relational databases. Then, we learned how to install MongoDB on all platforms, how to start the MongoDB server, and we explored the features of the MongoDB shell. The MongoDB shell is a tool that can be used to quickly check or perform CRUD operations, as well as many other operations in MongoDB. We looked at operator symbols for querying. Then, we introduced Go's MongoDB driver called mongo-driver and learned how it's used. We created a persistent movies API with the help of mongo-driver and Go. Finally, we learned how to map a Go struct to a JSON document.

Not every query is efficient in MongoDB. So, for boosting query performance, we introduced the indexing mechanism, which reduces the document...
