useInput()

const useInput: (inputHandler, options?) => void

This hook is used for handling user input. It's a more convenient alternative to using StdinContext and listening to data events. The callback you pass to useInput is called for each character when user enters any input. However, if user pastes text and it's more than one character, the callback will be called only once and the whole string will be passed as input.

import {useInput} from 'ink';

const UserInput = () => {
  useInput((input, key) => {
    if (input === 'q') {
      // Exit program
    }

    if (key.leftArrow) {
      // Left arrow key pressed
    }
  });

  return …
};
