NPM node validate expected version

Use package.json and add the lines

  "scripts": {
    "start": "node index.js",
    "test": "lab tests/api.tests.js",
    "preinstall": "node checkNodeVersion"
  "engines": {
    "node": ">=20",
    "npm": "^10"

First set the engines property to the version you wish to support, this is for Node 20 and up along with npm 10 or higher

Second add the preinstall check command of node checkNodeVersion to validate proper version

Third create a .npmrc file in the root folder of your nodejs application and put this in the file

engine-strict = true
