5 Fascinating Facts To Know About Node.Js Development

Node.js has gained huge success in a very little time. Its initial release was in 2009. Top companies that use Node.js are NASA, PayPal Netflix, Linked In, Uber and many more. It is proof that Node.js has been accepted worldwide. The common thing between all these companies is that they have a large user base all over the world.


While the expansion of JavaScript- a client-side scripting language is in the market, we needed something for the server-side programming. There has been a demand for server-side programming language among developers for some time now.


With a callback concept and being event-driven, Node.js has made a considerable step in that direction. We can use it along with other JS Frameworks and tools to create smooth user experiences in any operating system.

What Does The Inventor Say About Node.Js?

Ryan Dahl, the inventor of Node.js stated that being inspired by Gmail, his goal was to design a real-time push capability system for building websites. Earlier, only request/receive paradigm was possible but now with this, Australia's Mobile App Developers finally gained the possibility to make 2-way connection websites (server and client) with free data exchange between them.

Let us know more about, what is Node.js?

• Node.js is an open-source server environment.
• Node.js is free to use which is managed by the community.
• It supports various platforms like Windows, Linux, Mac, OS X, etc.
• Node.js uses JavaScript on the server and uses asynchronous programming.
• It can generate dynamic page content.
• Node.js can open, write, read, delete, and close files on the server.
• Node.js can collect form data and can modify, delete, add some data in your database.

More About Node.Js

• Node.js is a server engine that you can edit and adjust, and it will work after you set it up. The request processing feature provides a processing request as an event loop.
• It is a major reason why Node.js is essentially a runtime system. Being a part of the JavaScript ecosystem, which is great for website designing and mobile app development.
• It can be easily manipulated along with other JS tools, UI’s and connectors. JavaScript and node.js allows you to create simple web servers with just a few lines of code.
• But often people have some major misconceptions about Node.js development.

So now just bust out some major myths by truths.

MYTHS Node.js is a framework It only relies on Chrome V8 engine It does not support multi-threads Beginners can’t work with Node.js development.

TRUTHS It is basically a server capable of executing JavaScript It is an open-source system for building web applications It does, providing asynchronous and event-driven API’s Any programmer familiar with JavaScript can learn Node.js quickly.

Facts About Node.Js Development

Node.js is very distinctive in many ways. Probably, the most specific one is that it is a server-side platform. With Node, JavaScript is not only limited to the front-end only (working in the browser) but also allows work from the browser. Running code on the server results in fast processing capability.

There are a few other fascinating facts about Node.js development.

1. Javascript The Almighty- 

Are you aware that JavaScript is the simplest and the most popular used way to develop apps in the browser?

Well, it can be done with other programming languages, but it isn’t easy. You need to know a lot of basics and advance to do it.

Well, developers enjoy writing codes in JavaScript due to its features of ease of debugging and the dynamic nature of JavaScript makes it easy-peasy.

Node helps in solving the boundary that exists browser and server by enabling both the browser and server written in JavaScript.

In Node.js development you need to focus on two major parts one is JavaScript and the other is your database stack like MongoDB, PostgreSQL, or MySQL.

2. Powered By Google Chrome(The V8 Javascript Engine)- 

V8 is the name of the JavaScript engine that power google chrome. It provides the run-time
environment in which JavaScript executes. The DOM and other web platform APIs are provided by the browser which makes it easy to run.

What’s good about that?

Developer teams that are competing to advance JavaScript have made it one of the fastest and most dynamic runtimes.

Besides that, with google develop tools, you can perform debugging tasks in chrome57+, there is the node.js debugging feature by default and can be used to eliminate errors.

Other browsers have their own JavaScript engine like Firefox has Spider-monkey.

Safari has nitro and edge has chakra.

3. Reinforced With Json-

JSON stands for javascript notation format. It plays an important role in developing API’s and mobile applications. JSON is a robust and popular data exchange format as in real-time development either it is an app or website development there is always sending and retrieving of data.

it is one of the most important pillars of the javascript which allows developers to build quick APIs. it provides ease to fetch data for developers to use it in a dynamic way from the database.

The introduction of a general-purpose of JSON gave birth to NoSQL databases, like MongoDB. It was intended for JavaScript-only, but it is now an international standard.

4. The Power of Npm, Modules, and Instrument

NPM is the abbreviation of the Node Package Manager. It is included in the node by default.
It finds its place at the core of most deployment systems for Node.js and the node ecosystem has expanded significantly in recent years.

NPM consists of the command line and a database of packages aka registry. The packages make node more specials. It manages packages that are both local to a project and public javascript tools.

The package manager makes it easy for JavaScript developers to share the code they have created to solve specific problems and for other developers to reuse that code in their own application.

Asynchronous Feature In Node.Js  - 

JavaScript is asynchronous in nature and so is Node.js. Asynchronous programming is the design pattern that ensures no-blocking execution. It means a block of code does not engage with another block of code.

Basically, it ensures non-blocking execution of code which is totally independent of each other. This improves efficiency and throughput of the system. It is a little hard due to its Node.js callback scenario.

What is node.js great for?

1. Chat: A typical real-time application, a messaging chat app shows all that is best of node.js.

2. Server- side web apps: if you combine the features of node.js and express.js, you can make classic web applications on the server-side.

3. Data streaming: you can use node.js to create some positive features. Like processing files while they are just being uploaded for audio/video encoding.

4. Monitoring dashboards: to collect real-time data about website visitors and visualizations. User statistics and the ability to see what they are doing instantly, isn’t is great for business?

yes, it is. Use node.js to make dashboards systems nicely.

Pros Of Node.Js-

1. Easy to learn for developer familiar with javascript
2. It supports the caching of modules.
3. NPM- the biggest package manager in the software world.
4. It is also possible to stream large files.
5. Event driven I/O ensures better request handling.

Cons of node.js -

1. Inconsistently enhancing API of Node.js.
2. Node.js is not an optimal solution for tasks intensive on CPU taking in languages like c,c++ or c#.
3. There comes a split option about the asynchronous approach.

Conclusion- 

node.js is not perfect, but is a great tool for building server-side web applications in javascript.
Node.js is always evolving and expanding its use.
Node.js files have an extension of .js. files of node.js contain function that will be running on A typical event like when someone is trying to access a port on your server. It can be used to create add, delete, and modify data in your database.
