Best of the node. JS Tutorials and examples

If you are looking for the learning materials and guidelines for node. JS, then continue (read), our tutorials will cover instant chat apps, API Service authoring, poll apps, people voting apps, social licensing, node. js on Raspberry Pi, and more.

Here's a quick introduction to node. js, and if you have a little knowledge of node. js, you can skip this section directly.

So what is node. js?

node. JS is the most used server-side JavaScript runtime environment, using JavaScript to develop a cross-platform, real-time Web application.

node. JS is based on Google's V8 JavaScript engine. An event-driven, non-blocking input-output model, which also makes it efficient and lightweight.

The power of node. JS is that its capabilities support data-dense interactions, because the functions of such applications revolve around user events, data I/O, and data flow processing. The api,node.js of JSON is also magical, which is the heart and soul of a single-page Web application.

The popularity of node. JS can be felt, with large companies such as ebay, Target, City Group, Sony, Uber, LinkedIn, Medium, Netflix, and so on, being applied to their Web projects.

How to learn node. js?

The developers of node. js are from all over the world, and they use node. js to develop complex interactive, data-intensive web apps and websites. There are plenty of resources and tutorials online to teach you how to build your own node. JS application.

We don't have to look at the node. js great God's best guide for Web Apps.

The guides we cover will include node. js, intermediate guides for beginners, and how to build complex node. JS projects.

For complete node. JS Beginners, it's a good idea to follow the essentials of the airpair.com above, or the node. js Getting Started Guide, before digging deeper into the learning projects that are mentioned later in this article. Nodeschool.io is another good website with a lot of information to learn basic node. js and related technologies.

Build Instant messaging apps with express framework and Socket.io

The best way to learn a new technology at a certain height is through functional applications. In this guide, you will learn to build Instant messaging applications using the Express framework and Socket.io, which can use event-based bidirectional communication. In this guide, you will also use the JavaScript template engine jade.

The guide we are going to introduce is written by Krasimir Tsonev, Posted on tutsplus.com, built from the node. JS environment, using the Express framework's backend services, to the end of the front-end UI development using the Jade template engine, covers all aspects of the front-to-back.

Creating a restful API with swagger

This well-designed tutorial explains how to use swagger to create a rest API and includes all the operations that the rest API should support (CRUD, create, query, update, delete). This example is provided by Samuela Zara from Scotch.io, which implements the rest API for managing movie collections.

Swagger is a very powerful framework for describing rest APIs, which provides interactive API document editing, Client SDK generation, and discovery services. By using swagger, the API you write will be more easily understood and used by everyone.

In this tutorial, Samuela first teaches you how to install the Swagger module for node. js, and then describes the simulation mode provided by swagger. With this pattern, API developers can focus on the design of the API itself rather than writing a line of code. When this API structure is designed, the tutorial begins to take you through the action of getting movies, adding/modifying movies, and deleting movies.

You can access this tutorial through the restful API in the node. js using Swagger link.

Using nodal to establish API Services in node. js

On top of most modules and frameworks, you don't need to build any rudimentary javascript/node.js projects. For multi-platform (mobile, Web,iot) product development, service-oriented architecture is key, and this tutorial will take you further.

In this tutorial, Keith Horwood uses the nodal framework to create API services in node. JS and makes it all look very simple. Nodal is an extensible, opinion-based, full-service framework that helps data centers accelerate API creation on a node. js basis.

In this tutorial, you will install the node. JS Environment before developing MVC (models, controllers, and views), installing nodal and PostgreSQL.

node. js apps– use pass for social authentication

Social certifications are almost everywhere because most of us have their own accounts on a social network such as Facebook, Twitter and Google. Social network certification works by using existing social network certificates for single sign-on, while logging in to other programs.

In this tutorial, you'll build a simple node. JS program that uses social authentication to sign in using a pass as a middleware. This tutorial was written by Agraj Mangal and published on the Tutsplus.com website.

To obtain this tutorial you can access the link node. js apps–social authentication with Passport.

Developing voting apps with rethink DB and node. js

This tutorial is intended primarily for beginners who have a basic understanding of node. js. In this tutorial, you can learn node. js by developing a simple voting app that gives users three options for voting and provides real-time updates of the number of votes.

The angular and angural material Design Library is used for the front-end design of the program, node. JS is used on the server side, Rethink DB is used to store voting data and associated user data.

By writing a simple program like this, you can master all aspects of creating the entire program.

Develop a role voting app using react, node. js, MongoDB, Socket.io

This is a tutorial that advanced programmers have to read, and of course it's not the easiest example for beginners to learn. This is a well-organized tutorial written by Sahat Yalkabov to develop a role voting app for multiplayer online games, which is simply a full-featured project. Eve Online is a multiplayer online game where each player has a 3D image to represent their character.

This tutorial includes building rest APIs using the node. JS Framework, using MONGODB to save and retrieve data, using Socket.io to track online visitors in real-time, using react (and Flux) for service-side rendering, and finally deployment of the program to the cloud. In this tutorial, you'll be able to develop an app that will vote for EVE Online and learn a number of techniques in a fun and playful way.

For this tutorial you can access-character voting app–node.js, React, MongoDB and Socket.io

Wi-Fi dashboards using node. js and Reactive.js

This tutorial was written by Marcello La Rocca on sitepoint.com and is suitable for intermediate node. JS programmers. Marcello's lead comes from a previous series of tutorials, which also guides the creation of a dashboard to add more information about the surrounding Wi-Fi connection.

In this tutorial, you implement a server that runs on Ubuntu and makes little changes that can be run on Windows and Macs. The extension of the server implementation comes from the tutorial before Marcello-Create a battery using node. js. After the server is built, you write the client and user interface and use the HTML template to give the current Wi-Fi list.

Test-driven Development –node.js and Mocha

This tutorial, provided by Semaphoreci.com, will rendezvous you with Mocha for unit testing and integration testing.

Mocha is a JavaScript test framework that can run either in a browser or in a Nodejs environment. Mocha will perform all the tests sequentially and map the resulting uncaught exception to the appropriate test case.

You can introduce the Mocha module by using NPM. The example in this tutorial implements a color conversion program that converts RGB into 16 binary form. This tutorial also creates a Web server to test asynchronous code.

You can find this tutorial by following the link test driven development–node.js and Mocha.
