Which Node module provides the CLI prompt?

Question

I searched extensively and widely for a node module that provides a CLPL command-line interface like CLI for a node application.

What I'm looking for is a hybrid between inquirer or prompt and commander .

Node provides a built-in REPL module , however it just exposes the raw javascript of your application. I want to create a virtual interface for an application.

For example, if you run node server.js, you will be prompted:

server:~$

This will behave like a basic unix prompt in your own virtual context. Press enter:

server:~$
server:~$

Or help:

server:~$ help

Commands:

debug [setting]   Enables or disables debugging.
show stats        Displays live stats for your web server.

server:~$

And you can execute custom commands:

server:~$ debug on -v 7
Debugging turned on with a verbosity of 7
... live logging ...

, NPM ?

        var args = input.split(/\s+/).slice(1);

        var onoff = args[0];
        var verbosity = args[2];

        return "Debugging turned " + onoff + " with a verbosity of " + verbosity;

function eval(input, context, filename, callback) {
    var cmd = input.split(/\s+/)[0];
    var result = (cmds[cmd] || cmds["default"])(input, context);
    callback(null, result);
