Konami Listener

<konami-listener> is a web component that listens for the Konami Code. When a match is triggered, it will automatically show any content placed inside of the component, like so <konami-listener> <h1> Hello world! </h1> </konami-listener>

API

Simple Usage

<konami-listener> allows you to place any content inside of it. It will then be shown when the code is matched. By default, the container is absolutely positioned over the entire page, so style the internal markup accordingly.

<konami-listener>
  <h1> 💩 </h1>
</konami-listener>

Events

<konami-listener> emits the following custom events

To listen for events, just use addEventListener. Since it uses custom HTML events, the data payload is bound to event.detail.

const konami = document.querySelector('konami-listener');
konami.addEventListener('match', () => {
  console.log('Konami Code matched!');
})
konami.addEventListener('input', (e) => {
  const { key, index } = e.detail;
  console.log('Konami Code progress', { key, index });
})
