In this tutorial, we will see how to update Node JS in Ubuntu.

Prerequisites

NodeJS must be already installed on your Ubuntu machine. It is also recommended that nvm (Node Version Manager) must be installed on your machine, so that we can update NodeJS efficiently.

Updating NodeJS using apt

If NodeJS was installed using apt package manager in Ubuntu, it can be updated as well using the same.

sudo apt update sudo apt install nodejs

Note: Use apt-get instead of apt on older Ubuntu versions (version 14.04 and below).

Updating NodeJS using nvm

Node Version Manager, which is actually a Bash script to efficiently manage multiple Node versions on the same system, can be used to update Node.

Node has certain versions, which are deemed ‘Long Term Support’ (LTS) releases, for which support fixes are provided up to 30 months after their release. To update NodeJS to the latest LTS version, run:

nvm install --lts

To update to the latest stable release of NodeJS (Non LTS), run:

nvm install node

To update nodeJS to a custom version instead of the latest Node release, run:

#nvm install <node_version> #Eg. : nvm install 13.0.0
