use-secret-code

Custom hook for adding cheat codes to your React app.

Installation

npm install use-secret-code

What is this?

This is a custom React hook for adding "cheat codes" to your app. It will listen for a given sequence of keystrokes and track whether the corresponding "cheat" is enabled or disabled. You can then react (😏) accordingly (e.g. toggle a feature, pop an alert or notification, etc.). Just having a little fun here with this throwback to how we used to enter cheat codes in video games.

Package Name

This package was originally called use-cheat-code but apparently the word "cheat" is against npm policies, so they denied my attempt to publish the package under that name and I was forced to pick a new name. I went with use-secret-code (it's not great, but what else do you call a cheat code?), but I still export useCheatCode as well as useSecretCode. They are the same thing, but I will personally be importing useCheatCode in my own projects.

Usage

// import { useSecretCode } from 'use-secret-code'; // alternate
import { useCheatCode } from 'use-secret-code';

function CheatCodeExample() {
  const invulnerability = useCheatCode(['i', 'd', 'd', 'q', 'd']);
  return (
    <span>Invulnerability: {invulnerability ? 'enabled' : 'disabled'}</span>
  );
}

Browser Support

This should work in all modern browsers, but you'll need to polyfill Set for use in IE11. See the playground project in the example directory for one approach.
