The 2018 Web Developer : Getting the latest node modules

Look at the example package.json below, and in particular, the 'devDependencies' section.
{
  "name": "webpack-playlist-update",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
"devDependencies": {
    "babel-core": "*",
    "babel-loader": "*",
    "babel-preset-es2015": "*",
    "css-loader": "*",
    "sass-loader": "*",
    "style-loader": "*",
    "webpack": "*"
  }
}
The asterisks will tell npm to find the latest versions of those modules on the following command:
npm install
