If you have a Mac or Linux machine already, you already have a UNIX based operating system. All HYF-supplied laptops run Linux. If you have your own machine and it runs Windows, you should have set up a Linux partition.

❗❗Check if you already have NodeJS installed by running node -v in a terminal. The command should return a version number like v22.11.0. . If it does, you can skip the next steps.

On Ubuntu
Install nvm by running the following commands in your terminal:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
After the installation is complete, you’ll need to source the nvm script by running:
source ~/.bashrc
Install the latest LTS version of Node.js by running:
nvm install --lts
Check that you have successfully installed Node.js by running:
node -v
You should see a version number like v22.11.0.

Check that you have successfully installed npm by running:
npm -v
You should see a version number like 10.9.0.
