Node.js is an open source, cross-platform back-end development technology for building web applications. There are many software development company providing Node.js applications for business, that develop different types of applications with Node.js, such as real-time data applications (allow you to show all information in real time to users), interactive apps with Node.js to a page (means that the web app is updated by the client.

A dynamic page that changes according to the type of client, showing a personalized user experience for each use) and Data inputs (if you manage large databases, this allows you to solve bottleneck problems).

Node.js is absolutely perfect when it comes to developing applications that need to work in real time. Some practical examples developed with Node.js are social media applications, chat systems, image processing applications, personal management apps, web portals, back-end systems, and big data storage and manipulation apps.

Among companies using Node.js we can find Netflix, Uber, Walmart, Medium, POT, PayPal, Ebay, Trello and Godaddy. Professional developers are capable of developing any type of web application such as an ad portal, modules and plugins and a business tool for companies. Also, they can help connect API, Web and mobile devices using Node JS.

If you need to develop large and robust applications, Node JS is the best cross-platform application development system. An expert agency can guide you through the design and development process of your application with Node js.

Node JS is an easy-to-use open source software framework prioritizing scalability of projects created for cross-platform applications on both Android and iOS. It mainly focuses on developing MYSQL and PHP web applications. It provides simplicity through object-oriented practices. Node JS focuses on the security and performance of cross-platform applications, connecting projects through API systems.

Install NodeJS

Installing NodeJS is as simple as going to the Node page and downloading the executable that allows you to install the engine on your system. For Windows and Linux the process is as simple as installing any other program.

In Linux case, on the download page they explain what we have to do, since we must add the official repositories of the platform and then install the packages. In addition, the commands to carry out this process may vary between distributions.

Now, the recommendation to install NodeJS is to do it through a Node version manager, since it allows us to have several versions of the platform installed and exchange them whenever we want. This action is usually quite necessary if we develop projects in NodeJS, because many times there are version requirements depending on the case.

The most common version managers are nvm for Linux and Mac and n for Windows. Although there is an nvm for Windows, it is not as powerful and stable as Linux and Mac, so "n" could be more interesting.

Installing NodeJS through a node version manager has another advantage, which saves us some typical problems on Linux and Mac systems, where it is sometimes necessary to use "sudo" to install global npm packages, something that is not always recommended.
