njs-update

A bash script to check and install the latest Node.js version. Last installed Node.js global modules are installed to the new version and npm module is also updated. nvm module is required for the script to work. Also at least one Node.js version must be installed via nvm before script usage.  
 
 

Usage

Before using script, script file has to be marked as executable with the following command (after going to the script folder):

foo@bar:~$ chmode +x njs-update

Finally, it is recommended to add script folder to $PATH environmental variable.

To use the script you just type:

foo@bar:~$ njs-update

  • If the latest remote version is already installed in the system then:
    • npm module (on the latest Node.js version) is updated to its last version
    • .nvmrc file is updated in current folder for user to switch to new Node.js version
  • If the latest remote version is not installed in the system then:
    • Asks user if they want to install the latest remote version
    • If user chooses Yes then:
      • Asks user if they want to uninstall the last installed version, after new version has been insatlled.
      • New version is installed
      • All global modules of the last installed version are installed to the new Node.js version
      • npm module (on the latest Node.js version) is updated to its last version
      • If user has chosen to uninstall previous version, then this version is uninstalled from the system
      • .nvmrc file is updated in current folder for user to switch to new version
    • If user chooses No then:
      • npm module (on the last installed Node.js version) is updated to its last version
      • .nvmrc file is updated in current folder for user to switch to last installed Node.js version

 
After script execution user can use the new Node.js version on the current session by typing:

foo@bar:~$ nvm use

Note: Script creates/updates a .nvmrc file in the current folder in order for the above nvm command to work.
