chosen is a node module to make multiple-choice questions easy on CLIs.

npm install chosen

var choose = require("chosen").choose;

console.log("What is your favorite language?");
choose(
    ["English", "Klingon", "Malbolge"],
    function(answer, index) {
        console.log("I like " + answer + ", too!");
    },
    {} // options
);

You can feed any of the following options:

• style: one of [">", "gray", "indent"], or an object {normal: <function>, chosen: <function>}, where the functions return a formatted version of their inputs

chosen interaction was—ahem—chosen to be intuitive:

• <enter> and <space> select the current choice
• <esc> and <^C> to escape (sends null)
• (up arrow, down arrow), (k,j) (vim!),(q, a), and (p, l) for scrolling up/down (any other key defaults to "down")
