How to Install Node.js on Ubuntu VPS

The Node.js refers to a JavaScript platform which is used for server side programming and lets users create network applications faster. When you use JavaScript for both back-end and front-end, the development is more uniform and can be created within one system. The Node.js will allow you to make tools used for networking, web servers etc. This platform will make use of an event loop that means that all commands are run asynchronously.

How to Set up the Node.js on Ubuntu VPS:

Before you set up the Node.js on Ubuntu virtual servers you will need the SSH access to the server running Ubuntu 14.04. The Ubuntu 14.04 has the Node.js already inside its default repositories. But this version is far outdated and therefore it is recommended that you use PPA or Personal Package Archive that is maintained by Node Source. So, you must download the PPA and add this to the local configuration. When you need some other version like version 7 the command will be different. With this, you are free to install the Node.js on the Ubuntu 14.04 just like you would install any other package on it. When you have installed the Node.js you may check to see the exact version which has been deployed through a command. The Node.js platform comes with a NPM or packet manager which can help you install and run the Node.js packages.

The Node.js also comes with a NVM or a Node.js Version Manager. This allows you to set up many instances of the Node.js and also run them easily. Before you can install the NVM, you may need to install some tools. Finally, you will get a message which will prompt you to start using the NVM. You may either re-open the terminal or execute the mentioned commands for starting the NVM.

You need to confirm that this NVM has been set up properly and therefore you must type in nvm- -version. When you get version number it indicates that NVM has been properly installed. You may there after use this NVM to check all the Node.js versions. For installing the v7.1.0 version you can run "nvm install v7.1.0" command. This method may also be applied for installing and running other versions of the Node.js.

So, one can see that there are multiple ways to get the Node.js set up and running on your VPS hosting servers. The circumstances will actually tell you which of these available methods is best suited for the circumstance. The packaged version which is there in Ubuntu repositories is the simplest to use but the NVM method is believed to be the most flexible.
