Read on if you are looking for resources and tutorials to learn Node.js. We would be covering Node.js tutorial for Real Time chat application, writing API services, Polling app creation, Character voting app, Social authentication, Node.js on Raspberry Pi and many more.

Given below is brief introduction of Node.js for beginners, you can skip directly to the Node.js tutorials if you already know the basics of Node.js.

What is Node.js ?

Node.js is the most used server side JavaScript runtime environment till date and is used for developing cross platform real time web applications in JavaScript. 

Node.js is powered by the open source V8 JavaScript engine of Google and works on an event driven, non-blocking input-output model which makes it efficient and lightweight.

The power of node.js lies in its ability to support data intensive interactive applications that function around user events and deal with data I/O and data streaming. Node.js also works magical when it comes to JSON APIs and is the heart and soul of single page web applications. 

The popularity of Node.js can be gauged from the fact that big brands like eBay, target, City Group, Sony, Uber, LinkedIn, Medium, and Netflix too have used Nodejs for one or the other web development project.

How to Learn Node.js ?

Developers across the globe use Node.js for developing complex interactive and data intensive web apps and websites. There is no dearth of great resources and tutorials that teach you how to build your own Node.js applications.

Let us look at the best Tutorials around the web written by Node.js experts for creating kick-ass web apps. If you are looking for a proper course to master everything server side with Node.js, then here is the course that you should not miss - Server-side Development with NodeJS.

We will cover introductory Node.js tutorials for beginners, intermediate level Node.js tutorials and also the tutorials that teach how to build complex Node.js applications.

For the absolute node.js beginners, it is good to go through the step by step guides like the one on Udemy, or the Node.js tutorial on airpair.com before diving deep into fully functional example projects that are covered later in this article. Nodeschool.io is another great website with tons of resources to learn basics of node.js and related technologies.

Real Time Chat App with Node.js, Express and Socket.io

The best way to learn the depths of any new technology is by creating a fully functional application. In this tutorial you will learn to build a real time chat application using Node.js Express framework and socket.io that enables event based bidirectional communication. In this tutorial, you will also get to work with JavaScript template engine named Jade.

Tutorial is written by Krasimir Tsonev on tutsplus.com and covers all aspects of end to end app building, starting with node.js environment setup, backend server development using Express framework, and finally the front end UI development using Jade template engine.

Restful API in Node.js Using Swagger

This is another well written tutorial for learning node.js that explains how to write rest API services using Swagger and covers the end to end CRUD (Create, Read, Update, Delete) cycle. This tutorial is written by Samuela Zara on scotch.io and provides step by step instructions to create Restful API to manage movies collection.

If you haven't heard of Swagger, it is the most powerful framework that enforces specifications when it comes to documenting REST APIs. It offers interactive documentation, client side sdk generation and discoverability so that your APIs are easily discovered, described and used by developers. 

In this tutorial Samuela starts of with setting up Swagger module for Node.js, then uses the mock mode feature, which helps you start off with the APIs setup without writing single line of code. Once the structure is in place then you implement APIs for Get movie, Update movie, Add movie and Delete movie.

API Services in Node.js Using Nodal

With tons of modules and Nodejs frameworks around, you would never need to build any project from scratch in plain JavaScript/Node.js. For multi-platform (mobile, web, IOT) product development, service oriented architecture is the key and this tutorial takes you a step closer to that.

In this tutorial, Keith Horwood utilizes Nodal framework to create API services in Node.js and makes it look damn easy. Nodal is an extensible full service opinionated framework that helps speed up data centric APIs creation in Node.js.

In this tutorial you will setup node.js environment, install Nodal, setup postgreSQL before getting into coding the Model, Controller and Views.

Node.js Apps - Social Authentication with Passport

Social authentication is used almost everywhere since most of the people have accounts in one or the other social networks like Facebook, Twitter and Google. Authentication using social networking works like single sign on where you use your existing social network credentials and login to other applications.

In this tutorial you build a simple Node.js application and use social authentication for login using Passport as middleware. This tutorial is written by Agraj Mangal on tutsplus.com. 

You can follow this link for the tutorial - Node.js Apps - Social Authentication with Passport.

Polling App using Rethink DB and Node.js

This tutorial is mostly for beginners who have basic understanding of Node.js. In this tutorial you learn Node.js by building a simple polling app that gives users three choices to vote and provides live updates of the vote count.

Angular and angural material design library is used for front end design of the application, Node.js is used as the server and rethinkDB is used to store voting and user related data. 

You end up building a simple application while covering all aspects of end to end app creation.

Character Voting App – Node.js, React, MongoDB and Socket.io

This one is a must read tutorial for advanced level programming and definitely not among the easiest node.js examples for beginners to learn. It is a well-organised tutorial written by Sahat Yalkabov and is nothing less than a fully functional project for building a character voting app for online multiplayer game – Eve Online. Eve online is multiplayer online game where each player is represented by a 3D avatar. 

Tutorial covers building REST API using Node.js Express framework, saving and retrieving data from MongoDB, real time online visitors tracking using Socket.io, server side rendering with React ( and Flux) and finally deploying the application in the cloud. In this tutorial, you end up building an app for ranking avatars for Eve online and learn about multiple technologies in an interesting and fun way.
