Node.js Tutorial - For Beginners & Professionals

Creating a MEAN Stack SPA with CRUD Operations

MEAN stack stands for MongoDB, Express, AngularJS and Node.js. MEAN stack is a most popular full-stack JavaScript solution for developing fast, robust and scalable web applications. It uses MongoDB to store data in JSON/BSON formats which makes it well suited to use with JavaScript. It uses Express as Node.js web application framework. It uses AngularJS as front-end SPA development.

 

Setting up Visual Studio Code for Node.js Development

Visual Studio code is an awesome lightweight IDE for latest technologies development like AngularJS, Angular2, Node.js, TypeScript, ReactJS etc. I am a big fan of it and recommend it for Node.js development. This article helps you to set up Visual Studio Code for Node.js Development.

 

Brief history of node.js and io.js

Node.js was developed by Ryan Dahl and other developers working at Joyent. It was first released in 2009 supporting only Linux. Node.js was sponsored by Joyent Inc. and Node.js development and releases was under the governance of Joyent Inc.

 

Exploring REPL Terminal

REPL stands for Read-Eval-Print-Loop. It is an interface to run your JavaScript code and see the results. You can access REPL by simply running Node.js command prompt and simply run command node.

 

Exploring Node.js Core Modules

A module is a collection of JavaScript code which encapsulate related code into single unit of code. Node.js has a simple module loading system. A developer can load a JavaScript library or module into his program by using require method as given below:

 

Node.js vs. other Server Side frameworks

Today, Node.js is the most popular and widely used server side framework for small, large and any sized web app and web application development.

 

Advantages and Limitations of Node.js

Today, Node.js is the most popular and widely used server side framework for small, large and any sized web app and web application development.

 

Exploring Node.js Architecture

Node.js has mainly two types of components – core components and Node.js API (modules). The core components are written in C and C++, and node.js API are written in JavaScript. Diagram for Node.js architecture is given below:

 

Exploring Node.js Code Execution Process

By default, In Node.js all I/O operations like file I/O, database operations, network operations etc. are non-blocking. When these operations are completed, they are notified to the main thread using callback functions. You can also write blocking code for these operations using blocking version of Node.js functions which have Sync word as suffix.

 

Node.js Installation Guide

Node.js is platform which provides the complete solution for server-side applications, such as web platforms ASP.NET, Php etc. So, before going to start Hands-On Node.js, let's first install and configure it.

 

What is Node.js and Why to use it?

Node.js is a platform based on Google's V8 JavaScript Engine. Node.js is used to build fast, scalable network applications. It uses an event-driven, non-blocking I/O model that makes it lightweight, efficient and perfect for data-intensive real-time applications.
