NodeJS project backup script

NodeJS project backup script

The following shell script backups up the currrent node project by performing the following actions:

  • Assumes that the back script is bundled with the actual NodeJS projecxt foler.
  • Uses the current directory as the backup file name.
  • Moves to the parent folder to create a tarball using the project name and the current date stamp and excludes the node_modules folder.
  • Lists the backups created using the script.
