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.

Your first real-time web application


To get a better understanding of how all these components fit together, we're going to develop our first real-time web application based on Node.js and RethinkDB. If you've never developed a web app before, this is going to be very exciting for you!

You maybe wondering what we're going to build. We're going to develop a web application that allows us to create colored "notes" containing messages that can be dragged around the screen. The interesting thing about this web application is that it's completely real time. Everything you do will be reflected in real time on all connected clients. What this means is that if you open two browser windows and drag a note around, the same note will be animated in the other browser window. The same thing happens when you create or delete notes. All the changes will appear in real time in all the open browser windows without the need of reloading the page.

If you're curious, the application we're going to build looks...
