How to separate commands into files Vorpal.js

Question

I have many commands and each of them is long. For example, I have:

• create
• read
• update
• delete

I want to put them in separate files:

• ./commands/create.js
• ./commands/read.js
• ./commands/update.js
• ./commands/delete.js

and I want to require them in app.js:

require('./commands/create.js');
// ...

so I can:

node app.js create HelloWorld

How can I achieve this?

Answer 1

I would do something like this:

// create.js

function create(args, cb) {
  // ... your logic
}

module.exports = function (vorpal) {
  vorpal
    .command('create')
    .action(create);
}

Then in your main file, you can do:

// main.js

const vorpal = Vorpal();

vorpal
  .use(require('./create.js'))
  .use(require('./read.js'))
  .show();
