Getting Started with RethinkDB

By: Gianluca Tiepolo

Overview of this book

RethinkDB is a high-performance document-oriented database with a unique set of features. This increasingly popular NoSQL database is used to develop real-time web applications and, together with Node.js, it can be used to easily deploy them to the cloud with very little difficulty. Getting Started with RethinkDB is designed to get you working with RethinkDB as quickly as possible. Starting with the installation and configuration process, you will learn how to start importing data into the database and run simple queries using the intuitive ReQL query language. After successfully running a few simple queries, you will be introduced to other topics such as clustering and sharding. You will get to know how to set up a cluster of RethinkDB nodes and spread database load across multiple machines. We will then move on to advanced queries and optimization techniques. You will discover how to work with RethinkDB from a Node.js environment and find out all about deployment techniques. Finally, we’ll finish by working on a fully-fledged example that uses the Node.js framework and advanced features such as Changefeeds to develop a real-time web application.

Running Node.js


Now that Node is installed and configured, we're ready to start using it. However, before trying this, let's just verify that Node is installed correctly by printing its version number.

This book assumes that you're using the latest stable version of Node.js. If you have installed a different version, for example, by building from the latest unstable source code, then the examples in this chapter might not work. From the command line, you can run the following command to see which version you have installed on your system:

node --version

If the command is successful, the output will be Node's version number.

Note

At the time of writing this book, the latest stable release was Node v4.2.2.

Node provides a JavaScript runtime environment that can be accessed at any time by running the node command from your command-line or terminal window. This feature is called the CLI (command-line interface), and it allows you to experiment with Node. For the purpose of this book, you will be...
