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.
