React Keyboard

React + Typescript cheat sheet

Make the App a class component with pressedKey in the state.

Here is the working version

• before any key was pressed show the Nothing was pressed yet message;
• when a key is pressed show a The last pressed key is [key] message;
• use componentDidMount to add keyup handler:

  // DON'T import KeyboardEvent from React, because it is a regular event
  document.addEventListener('keyup', (event: KeyboardEvent) => {
    console.log(event.key);
  });

• use removeEventListener to remove a global handler in componentWillUnmount.
