Mastering RethinkDB

By: Shahid Shaikh

Overview of this book

RethinkDB has a lot of cool things to be excited about: ReQL (its readable,highly-functional syntax), cluster management, primitives for 21st century applications, and change-feeds. This book starts with a brief overview of the RethinkDB architecture and data modeling, and coverage of the advanced ReQL queries to work with JSON documents. Then, you will quickly jump to implementing these concepts in real-world scenarios, by building real-time applications on polling, data synchronization, share market, and the geospatial domain using RethinkDB and Node.js. You will also see how to tweak RethinkDB's capabilities to ensure faster data processing by exploring the sharding and replication techniques in depth. Then, we will take you through the more advanced administration tasks as well as show you the various deployment techniques using PaaS, Docker, and Compose. By the time you have finished reading this book, you would have taken your knowledge of RethinkDB to the next level, and will be able to use the concepts in RethinkDB to develop efficient, real-time applications with ease.

Preface

Creating a Node.js server and routes


We need an HTTP server to expose API's and serve static files to the browser. To create a server in Node.js, Express.js is the node module that is very stable, popular, and widely used.

So let's begin. The first thing we require is a package.json file. The recommended way to do it is by using the npm init command.

Tip

Use npm init --y to avoid answering the prompt questions.

Here is the sample package.json for reference:

{ 
  "name": "polling-app-node-rethinkdb", 
  "version": "1.0.0", 
  "description": "", 
  "main": "app.js" 
} 

Once the package.json is created, we can install dependencies that are required to run the project. They are:

  • Express: Web framework.

  • RethinkDB: RethinkDB official client driver

  • Socket.io: Socket module for message exchange to the client

Along with this, we also need the following dependencies for development purposes:

  • Async: Asynchronous handling utility

  • Body-parser: Middleware for parsing the incoming...
