Baic knowledge for package.json

In this article, I would like to share basic knowledge for package.json

🍮 Restrict Node version

If you want to keep node.js version in your project, please write following configuration in package.json:

{
  "engines" : { "node" : ">=8.9.4" }
}

If you use nvm and you put .nvmrc, you can use specific version of node.js.

🚜 License for private product

For preventing publishing the product to npm libraries, please set "license": "UNLICENSED" and "private": true:

{
  "license": "UNLICENSED",
  "private": true
}

🎂 Special Thanks
