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.

Installing MongoDB and using the shell

MongoDB can be easily installed on any platform. On Ubuntu 18.04, we need to perform some steps before running the apt-get command:

sudo apt-get update
sudo apt-get install -y mongodb

Once you've installed it, check whether the mongo process is running. If not, you can start the MongoDB daemon using the following command:

systemctl start mongod

If the user is root, you can drop the sudo keyword before each command.

We can also download MongoDB manually from the website and copy it to /usr/local/bin. To do this, we have to create an init script for the server since the server stops when the system is shut down. We can use the nohup tool to run the server in the background. Usually, it is better to install it using apt-get.

To install MongoDB on Mac OS X, you'll need to use the Homebrew software. Follow these steps to do so:
