Best way to install Node.js and NPM

I’m writing this post as I need to install node.js and npm to install packages for reveal.js, I’m on Ubuntu 18.04 Bionic.

Normally we can install node.js via terminal by

sudo apt install nodejs

But this is not the best way since the version is outdated and some dependencies won’t meet. The best way to install the latest node.js and npm is via nvm.

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

Note that the version number can be checked by going directly to the website and see. The above script will download all the package and put nvm into the Linux alias (so we can use the nvm command globally). After this, log out and log in to activate the alias.

Once you log in, run below script

nvm install node

To update:

nvm install node
nvm alias default nodenvm install node
nvm alias default node
