Are you considering becoming a Node.js developer, but you are not sure where to begin? Well, you don’t need to be an expert in programming to understand Node.js. But a general knowledge of programming environments is necessary.

If you are just starting as a Node.js developer, you will find this article useful as it provides a comprehensive list of resources for learning the platform.

Stay on this page to learn more.

Node.js: how does it work?

Node.js was created by Ryan Dahl in 2009, primarily as a client-side scripting language. It operates on the Google Chrome JavaScript V8 engine, as an open-source, cross-platform framework.

It is a highly scalable platform that enables you to make simultaneous connections without having to open several processes or read the codes line by line.

The newest version of Node.js is 10.10.0.

Who can benefit from Node.js?

Node.js was initially developed by JavaScript developers to be able to run the language out of the browser environment.

The Chrome V8 engine allows JavaScript to be easier and quicker to ignore compilation.  

As a result, Node.js not only enables you to design interactive websites but also makes them more agile and capable of interacting with other sequence languages like Python.

This is why developers use it specifically in network applications where speedy and agile processes are a requirement, like the development of APIs, web apps with Ajax, push messaging. and most of all, the Internet of Things.

On the other hand, it is not the most useful platform for calculations and data processing.

Node.js: the benefits of using it.

Web developers use Node.js because of its incredible features. Here are some of the Node.js features:

  • Quicker execution of the code
  • No buffering
  •  High scalability
  •  Non-blocking API

Thanks to these amazing features Node.js is vastly used for creating server-side and network applications. These are the most popular areas where it is used:

  • Applications related to I/O
  •  Single-page applications
  • Applications for transmission of data
  • Applications based on JSON API
  • (DIRT) Real-time data-intensive applications

Microsoft, PayPal, Yahoo, IBM, Netflix LinkedIn, General Electric, eBay, and many more, are just a small example of world-famous enterprises to use Node.js.

Disadvantages of Node.js

For computationally intensive applications, JavaScript and C don’t have the capacity to compete.

As a result of the limits of the memory design of the V8 engine, the maximum heap in a 32-bit environment is 1G, and for 64-bit environments less than 2G. This makes it impossible for Node.js to read 10G data at the same time.

A large gap exists from Nginx in static resources handling, despite the advantage of IO-intensive applications.

Node.js App scenarios

Now that you have a basic understanding of Node.js, let’s take a look at the application scenarios.

  • Express – a framework for the web application, to help you create websites faster.
  • JavaScript  template engine generating HTML codes.
  • Mongoose – to help you execute operations and access the MongoDB model tool.
  • MySQL – an API for communication.
  • Restify – REST-based framework that supports the server and the clients.
  • – software that supports the WebSocket protocol for communications, completely adopted by JavaScript.
  • Cheerio/Request – a toolkit specifically designed for the server, which is quick, versatile, and encapsulates the principal function of jQuery. 8 times quicker than JSDOM.
  • Hexo – easy, lightweight, and static framework for blogging. 
  • Node club – a software community with a slick interface, quality features, quick and light, especially popular in the Chinese Node.js community.
  • Blade – a tool for making slideshows in a matter of seconds.
  • Bower.js – a package management tool created by Twitter, for the distribution of functions in modules.
  • Passport – a login authentication tool.
  • Later – a library of tools in Nodej.js, that performs easily and can operate in Node and browser.
  • Browserify – a tool that enables Node.js to run in the browser.
  • Commander – a programming tool that provides users with powerful functions for parameter parsing and command-line input.
  • tty.js – a console tool that supports executions in the browser (works with vim, mc, irssi, vifm syntax; 256 color screen; multi-tab window model).
  • Node-WebKit – a framework for app development on Windows and Linux. Works with favored web technologies like Node.js, JavaScript, HTML5.
  • Node-os ­­­­­– an operating system created with Node.js.
