Before getting to the tutorial of how to install node.js, first let us understand the general concept of it. It is a JavaScript platform that is used for general purpose programming that allows user to build network applications faster. By including JavaScript into both front and backend, node.js makes the consistent and integrated system of work. Here in this article, you will understand lot more about the node.js.

Before installing Ubuntu, you should have access to the non root user account that has sudo privileges set up on system. Here we will check for the initial server setup tutorial for Ubuntu. As Ubuntu in default has Node.js in its repository. This can be used to provide a consistent experience across multiple systems. So you have to analyze the version. It will help in understanding the different versions, packages archives or version managers. Here we can read the knowledge base article on node,js along with more flexible and robust methods of installation.

If the JavaScript is not present in the operating system, we should get through the installation phase. Thus, it can be installed using PPA and NVM. Here is the brief description of both installations. This will help in understanding the purposes.

• Installation using PPA

This is used to install the recent version of java script. If you are having the out dated version of java package, then you can add personal package archive that is maintained by node source. This has up to date version of Node.js in the repositories

• Installation using NVM

Another alternative source to install Node.js is through access of tool called NVM. This NVM stands for Node.js Version Manager. This works at the level of independent directory rather than working at operating system level. You can install multiple self contained version of java script without affecting the entire system. By controlling the NVM mode, you will have access to the newest version and stay up to date by managing the previous releases.

• Removing Node.js

Using NVM or apt, you can uninstall Node.js. It can be carried out depending upon the versions you have to target. To remove the whole version, you need to work with system level. This will help with uninstalling the current version with the uninstall command. This will remove the files associated with the targeted version.

As you have understood the installation and removal of latest java script, you can understand further with the help of exact guidance. Check for latest updates in the Node.js file and get the cached file.
