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

Running the app


So far, we have done lots of coding. It's time to test it. Before running the code, start all the databases: RethinkDB, MySQL, and MongoDB.

To run the code, go to the project directory and execute the following command from the terminal:

node app.js

It will start the Node.js server and you should be able to see a similar screen to the following:

If you are running the code base in a local machine then you need to call these APIs using CURL or any API simulator:

GET /users - to retrieve all users data 
POST /users - to create new user 
PUT /users - to edit the user detail. 
DELETE /users - to delete the user. 

Let's begin by creating a new user. We have already used the API simulator in previous chapters so let's use CURL to make the API request.

Execute the following command from the terminal to make the request:

curl -H "Content-Type: application/json" 
-X POST  
-d '{ "name": "Shahid", "dob": "03/18/1992", "gender": "male", "location": "mumbai" }' http://localhost:4000
