Installation
Check if you already have node installed or not. If a version is returned, this means node is installed
node -v
Installing node using Node Version Manager NVM. NVM helps manage multiple version of node installation simultaneously
Download NVM setup and install. In case you want to update the existing NVM install, you need to download the latest version and install.
Once installed you can run this command
nvm ls
nvm list
If node is installed it will return the version installed, if not it will return blank. In both the cases if you want to install or upgrade to latest node version just run
nvm install latest
To install LTS version of node (for logn therm stability)
nvm install lts
To list and install any specific version of node
nvm list available
then
nvm install node-version-number
Once you install a version of Node, the corresponding version of NPM (node package manager) is installed for you. So you don’t need to install NPM separately.
To use a specific version of node
nvm use lts
nvm use latest
nvm use node-version-number
To uninstall a node version that you dont want to use
nvm uninstall node-version-number
To check what node modules or packages are installed, use the command
npm -g list
