install nodejs on Ubuntu

 

 

Option 1: NodeSource (system-wide, for production servers)

Good if you want a fixed version (LTS or Current).

1. Update your package index:

 

sudo apt update sudo apt install -y curl

2. Add the NodeSource repository (replace 20.x with 18.x or 22.x if you want a different line):

 

curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -

3. Install Node.js + npm:

 

sudo apt install -y nodejs

4. Verify:

 

node -v npm -v
