Run several javascript file dynamically using same npm run command

Question

My folder structure:

app

  Model

    user.js
    post.js

My package.json file

"scripts": {
    "migrate": "node ./app/Model/"
}

I want to run javascript file in command line dynamically.

Like:

npm run migrate user.js
npm run migrate post.js

Is there any way to achieve this?

You could write a script that dynamically requires the decired js file.

"scripts": {
    "migrate": "node model.js"
}

Then model.js like this:

const path = require('path');    
require(path.join(__dirname, 'app', 'Model', process.argv[2]));

@ShivamChhetri I don't have node on my current machine. So i cant test it. But it looks like the first argument in process.argv is a ref to node. try process.argv[1] instead. And remember the --

It's working with process.argv[2] and there's no need of -- before user.js

"scripts": {
"migration": "node Model.js"

}

const program = require('commander');

program
    .command('f <file>')
    .description('Database migration.')
    .action(async (file) => {
        console.log(file);//do something here
    });


program.parse(process.argv);

npm run migration f post.js
