About to write to C:\Drupal-Miscellneous\Drupal Study\Node JS\package.json:

{
  "name": "sanidev",
  "version": "1.0.0",
  "description": "sani dev mahima",
  "main": "surya.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "kamlu",
  "license": "ISC"
}


Is this OK? (yes) yes
