strict-npm-engines

Enforce the NPM and Node versions specified in the package.json "engines" property.

Install

npm install strict-npm-engines --save-dev

yarn add strict-npm-engines --dev

Requirements

Requires node 7.6 or higher for Async/Await.

How to use

1. Add the engines field to your package.json, like this:

{
  "engines": {
    "node": ">=8",
    "npm": ">6"
  }
}

You can read more about engines in the npm documentation

2. Install strict-npm-engines (documentation above)

3. Add strict-npm-engines to your npm scripts.

{
  "scripts": {
    "start": "strict-npm-engines && node ./index.js"
  }
}

If an incorrect npm or node version is used, an error message will be printed, and the process will exit with an error. Like this:

Invalid node version. Expected >=12 but got 8.16.0.

If the engines satisfy the range, the process will exit without an error.
