    force-npm

    Force users to use npm instead of yarn.

    If run from yarn instead of npm, the process will exit with error code 1 and print an error message.

    Note: this will not work if used with yarn add --dev --ignore-scripts. Note: This is fork of use-yarn

    Install

    npm install --save-dev force-npm 
    # or 
    yarn add --dev force-npm 

    Use

    CLI

    For example, in your package.json:

    {
      "scripts": {
         "preinstall": "force-npm || ( npm install --save-dev --no-scripts --no-save force-npm && force-npm )"
      }
    }

    Or if you're on npm >=5 or have npx:

    {
      "scripts": {
         "preinstall": "npx force-npm"
      }
    }

    You may provide a custom message via the -m flag:

    {
      "scripts": {
         "preinstall": "npx force-npm -m 'Please use npm!'"
      }
    }
    

    Or, you may also provide a custom message read from a file via the -f flag:

    {
      "scripts": {
         "preinstall": "npx force-npm -f path/to/customMessage.txt"
      }
    }
    

    You may disable force-npm by setting the DISABLE_FORCE_NPM environment variable to true:

    {
      "scripts": {
         "preinstall": "DISABLE_FORCE_NPM=true npx force-npm"
      }
    }
    

    API

    var forceNpm = require('force-npm')
     
    forceNpm()
     
    // or a custom message
    forceNpm('You idiot!')
