Building RESTful Web services with Go

Explore the necessary concepts of REST API development by building few real world services from scratch.

Key Features
Follow best practices and explore techniques such as clustering and caching to achieve a reactive, scalable web service
Leverage the Gin Framework to quickly implement RESTful endpoints
Learn to implement a client library for a RESTful web service using Go
Book Description
REST is an architectural style that tackles the challenges of building scalable web services and in today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs. The depth, breadth, and ease of use of Go, makes it a breeze for developers to work with it to build robust Web APIs. This book takes you through the design of RESTful web services and leverages a framework like Gin to implement these services.

The book starts with a brief introduction to REST API development and how it transformed the modern web. You will learn how to handle routing and authentication of web services along with working with middleware for internal service. The book explains how to use Go frameworks to build RESTful web services and work with MongoDB to create REST API. You will learn how to integrate Postgres SQL and JSON with a Go web service and build a client library in Go for consuming REST API. You will learn how to scale APIs using the microservice architecture and deploy the REST APIs using Nginx as a proxy server. Finally you will learn how to metricize a REST API using an API Gateway.

By the end of the book you will be proficient in building RESTful APIs in Go.
