How To Install Node.js on Ubuntu 20.04

Installing Node.js on Ubuntu 20.04 can be done using a few different methods. Here’s one of the most common ways using the official NodeSource repository:

Method 1: Using NodeSource Repository

1. Update package lists:

                   
                       sudo apt update
                   
               

2. Install necessary packages:

                   
                       sudo apt install curl -y
                   
               

3. Install Node.js from the NodeSource repository:
   • Add the NodeSource repository:

                             
                                 curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
                             
                         

     (You can replace 14.x with the version you want to install, like 16.x for Node.js 16)

   • Install Node.js and npm:

                             
                                 sudo apt install nodejs -y
                             
                         

4. Verify the installation:

   Check the Node.js version:

                   
                       node -v
                   
               

   Check the npm version:

                   
                       npm -v
                   
               

Method 2: Using the Default Ubuntu Repository

1. Update package lists:

                   
                       sudo apt update
                   
               

2. Install Node.js from the default Ubuntu repository:

                   
                       sudo apt install nodejs npm -y
                   
               

3. Verify the installation:

   Check the Node.js version:

                   
                       node -v
                   
               

   Check the npm version:

                   
                       npm -v
                   
               

Choose the method that suits your preferences. Method 1 allows you to install a specific Node.js version by choosing the appropriate NodeSource repository, while Method 2 installs the versions available in the default Ubuntu repository.
