I stumbled upon this great React Hooks library called Rooks recently and it has got a lot to offer. We all have discovered various Easter eggs in various apps and sites. It can range anywhere from stumbling upon a Rick-roll when you click a button a certain number of times or enjoying playing snake when you press a hidden button on a 404 page.

Ok, so let us start making an Easter egg 🥚

An alert when you press a certain key combination

Rooks provides us with a very useful useKeys hook. With this, we can trigger an action whenever a certain key combination is pressed. For this example whenever the keys Q, W, E, R, T, and Y are pressed, all together, an alert will be triggered saying the key combination was pressed. This is a simple example and hence a great place to start

Firstly we need to create a react project (you can use Gatsby, NextJS, etc as well as long as it is React). I am using Codesandbox for this tutorial but you can do it locally as well.

Now we need to install rooks so we can run

npm i - s rooks

You can following the getting started guide for rooks.

Now let us see the code

Firstly, we need to import the hook:

import { useKeys } from "rooks";

Now we need to configure the hook:

useKeys(["KeyQ", "KeyW", "KeyE", "KeyR", "KeyT", "KeyY"], () => {
    alert("QWERTY");
});

Here, the first parameter is an array of all the keys that need to be pressed. We pass in a callback function which will be triggered if all the keys are pressed as the second parameter.

Now whenever the 6 keys are pressed together, we will see this alert -

Now we have successfully made our first Easter egg 🥳!!!

Now it is time for you to explore other hooks and come up with some great Easter eggs for your site.
