Synchronus get character in Node.js

I want to get one character at a time synchronously from the terminal and read it in as soon as a key is pressed. I am having troubles getting it working on windows and it should work like getc() in C/C++.
console.log("Other code!");
x = getCharcter(); //not sure how to do this synchronously
process.out.write(x);
console.log("More code!");

Try this:
const readline = require('readline');
readline.emitKeypressEvents(process.stdin);
process.stdin.setRawMode(true);
process.stdout.write("press character: ")
process.stdin.on('keypress', (str, key) =>
process.stdout.write("[pressed " + key.name + "] ")
if (key.ctrl && key.name == 'c') process.exit();
)

This is still an asynchronous call. The on key press starts a new thread.
