Overview of this book

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.

Preface

Kong CLI


Kong comes with a command-line tool for changing the behavior of Kong. It has a set of commands to start, stop, and modify Kong. Kong by default uses a configuration file. If we need to modify it, we need to restart Kong for those changes to be applied. So, all these housekeeping jobs are already wired into the Kong CLI tool. The basic functions are:

  • kong start: For starting the Kong server
  • kong reload: For reloading the Kong server
  • kong stop: For stopping the Kong server
  • kong check: For validating the given Kong configuration file
  • kong health: For checking necessary services, such as the database, are running

Please go through the documentation of Kong CLI for more commands at https://getkong.org/docs/0.9.x/cli/.
