Node.js : need help to create command line interface

Question

I'm developing command line interface with node.js. Can we have custom console like mysql? Like, if we type mysql and enter in console it will come as mysql> so we can do all mysql related operation until we exit. Like that in node.js

> node hello
hello> help
hello> list apps
.
.
hello> exit
>
>node world
world>operation related to world
.
.
world>exit
> 
// or if it is executable
>hello
hello>help
hello>list app
hello>exit
>

It would be great if you give some suggestion.

Seems like you want to create a REPL. Check this out, though I haven't tried something lime it myself: How to create and use a custom REPL — laggingreflex

Yes. Check out Vorpal.js. It was made for this exact purpose.

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

... // your app code

vorpal.command('list apps')
  .action(function (args, cb){
    var self = this;
    myapps.forEach(function(app) {
      self.log(app.name);
    });
    cb();
  });

vorpal
  .delimiter('hello>')
  .show();

And then you'll have this:

$ node hello.js
hello> list apps
..
..
hello>

Disclaimer: I wrote Vorpal.
