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.

Exploring the JSONStore feature in PostgreSQL

PostgreSQL >9.2 has a prominent feature called JSONStore. PostgreSQL introduced two new data types for 9.2">storing JSON data. PostgreSQL allows users to insert JSON data as a json field or a jsonb field. It is quite useful for modeling real-world data that has to be more flexible in its structure. PostgreSQL draws on the best of both worlds by allowing us to store JSON strings as well as relational types.

The main difference between json and jsonb is that the json field stores data as plaintext whereas jsonb stores that same data as a binary field. Each has its own benefits. For example, the json field commonly takes up less space than jsonb because it is a straightforward insert, but the jsonb field indexes JSON for better querying. You should choose the right field depending on whether the JSON document is fetched as...
