Here's how you can asynchronously read a single character in Node.js, using the <code>keypress</code> package.
<lang javascript>var keypress = require('keypress');
keypress(process.stdin);
process.stdin.on('keypress', function (ch, key) {
if (key && (key.name === 'y' || key.name === 'n')) {
var reply = key.name === 'y';
console.log('Reply:', reply);
// ...do something with 'reply'...
}
});
process.stdin.setRawMode(true);
process.stdin.resume();</lang>
This does not seem to be possible to do synchronously in Node.js or at all in the SpiderMonkey shell.
