How to specify/enforce a specific node.js version to use in package.json?

Even though engineStrict is deprecated, you can still accomplish this behavior without needing to use an additional script to enforce a Node version in your project.

1. Add the engines property to your package.json file. For example:

   {
     "name": "example",
     "version": "1.0.0",
     "engines": {
      "node": ">=14.0.0"
     }
   }
   

2. Create a .npmrc file in your project at the same level as your package.json.

3. In the newly created .npmrc file, add engine-strict=true.

   engine-strict=true
   

This will enforce the engines you’ve defined when the user runs npm install. I’ve created a simple example on GitHub for your reference.
