Interactive Command Line User Interfaces In Node

The Command npm init, ask a series of questions and gets those answer and write it in a file? How can I create a similar command line utility in node? Is there any packages availab

Solution 1:

The inquirier package should meet your needs. Have a look at the examples they provide here on github

Solution 2:

Vorpal.js is built on top of Inquirer.js, and provides an interactive CLI, with an easy API for adding commands, which seems to be what you are looking for.

Implementing is easy:

var vorpal = require('vorpal')();

vorpal
  .delimiter('myapp$')
  .show();

vorpal
  .command('foo', 'Logs "bar".')
  .action(function(args, cb){
    this.log('bar');
    cb();
  });

Your app is now interactive:

$ node app.js
myapp$ foo
bar
myapp$

Disclaimer: I wrote Vorpal, so if you have questions, ask away.
