What Is Nodejs
Nodejs is an open-source server-side runtime environment that runs on on Google Chrome V8 JavaScript engine. It provides an event-driven, non-blocking input/output system and cross-platform runtime environment for building highly reliable and scalable server-side applications using JavaScript.
Nodejs is so powerful that supports to building of a wide range of applications such as live-streaming applications, REST API, server-based web applications, a real-time communication application, etc.
However, Nodejs comprises numerous concepts that help in building multi-user network applications, and web servers, similar to PHP, and ASP.NET.
HISTORY AND RELEASES
Nodejs was initially implemented in the year 2009 by Ryan Dahl. Within a short period (i.e. 10 years), Nodejs has grabbed an irreplaceable position in the web application development sector.
With JavaScript, Nodejs proves its power and ability in the web app market and dominating to date. Nodejs platform has an extensive feature that helps to show the capability of JavaScript on the server.
In 2009 Nodejs released in the market with its first-ever version of package manager called Node Package Manager(NPM) and still releasing their updated versions (From Nodejs 1.0 to Node.12) in a regular time interval. The latest version of Nodejs is node.13.0.1 was released in 2019 and continues.
NODEJS ARCHITECTURE
Nodejs uses a Single-threaded Even-Loop Model Architecture, which allows all the client requests in Nodejs to be executed by a single-thread operation. It is not just a single-threaded but event-driven nature as well helping the Nodejs application to handle multiple client requests concurrently.
INSTALLING NODEJS
Moving to the next step from learning Nodejs, Installing this platform can be done with a simple procedure. To download the latest and stable version of Nodejs, just visit the official Nodejs site. But before you install, make sure that your machine has enough storage space and a minimum RAM of 4 GB.
NPM(NODE PACKAGE MANAGER)
Once you are done with the installation procedure, the next step is to learn about NPM- Node Package Manager acts as the core of any Nodejs application that comes with 750000+ bundle of packages.
These libraries of great tools that help every developer in Nodejs application development. This NPM is essential in speeding up the application development process.
JSON FILE
JSON File is an integral part of the Nodejs application development. Before starting working on a Nodejs project, all you need is to create JSON as the first file. It is the manifest file that holds the metadata of the project.
These files are used along with the scripts for managing the dependencies used in the projects. Mostly JSON files of your Nodejs project are required for generating builds and running tests.
NODEJS BASICS
Since Nodejs is a JavaScript framework, to execute a simple “Hello world” in Nodejs, all you need to know is the basics of concepts like variables, data types, operators, functions, etc in JavaScript.
Then before you start with Nodejs, you need to get a clear understanding of what is JavaScript for the betterment of development.
FILE SYSTEM
This is a crucial step in Nodejs installation that allows us to read and write data into a file rather than on a console. Nodejs uses an fs module to access the physical file system from a directory.
EVENTS
Nodejs is most popular for its event-driven applications. Each Nodejs application is based on a single-threaded and perfect event-driven architecture that supports concurrency. You need an event module to create and handle custom events.
HTTP MODULES
HTTP’s modules are a key functionality in Nodejs which is highly used for developing server-based applications. With Nodejs, you can create an effective REST API using the HTTP module.

FRAMEWORKS
Creating a Nodejs application from scratch by writing code for every function is a time-consuming process. To avoid such scenarios, Nodejs provides several frameworks that will help you in the faster building of web applications with rich features. Here, are a few of the popular Nodejs frameworks:
- Express.js
- Adonis.js
- Meteor.js
- Nest.js
- Koa.js
DATABASE
As of now, you will know basic ideas to develop a whole functional Nodejs application. Running an application requires large storage of data in a database.
Nodejs allows you to choose any database based on your application requirements. Here we list some best-fit databases that greatly support Nodejs applications.
- MySQL
- MongoDB
- Cassandra
- Oracle
- CouchDB
