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.

Installing MongoDB and using the shell


MongoDB can be easily installed on any platform. On Ubuntu 16.04, we need to perform some processes before running the apt-get command:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6 

echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

sudo apt-get update && sudo apt-get install mongodb-org

It will ask for confirmation of installation in the last step; press Y. Once the installation is done, we need to start the MongoDB daemon using the following command:

systemctl start mongod

All the preceding commands are to be run by the root. If the user is not root, use the prepend sudo keyword before each command.

Note

We can also download MongoDB manually from the website and run the server with the ~/mongodb/bin/mongod/ command. For this, we need to create an init script because the server will...
