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!");






node.js synchronization

  • Try robotjs, it can detect key presses.

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();

})
