Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

cb-Konami-js

WebサイトにKonamiコマンドを実装するJavaScriptプラグイン。

About

キーボードでKonamiコマンド**「上上下下左右左右BA」**を打った後に、何か任意の処理を実行させる機能を実装することができます。

以下の例では、キーボードの[↑] + [↑] + [↓] + [↓] + [←] + [→] + [←] + [→] + [B] + [A] を打った後に、「konami」とアラートが表示されます。

(function () {
  var konami = new Konami();
  konami.init();
} ());

Demo

http://jsrun.it/maechabin/UoiG

Usage

distディレクトリ内の「konami.min.js」をページに読み込みます。

<script src="../dist/konami.min.js"></script>

<body>の閉じタグの直前に以下を挿入。Konamiオブジェクトのインスタンスを作成し、initメソッドを実行。initメソッドの引数には、コナミコマンド入力後に発動させたい処理(関数)を指定可能。

<script>
(function () {
  var konami = new Konami();
  konami.init();
} ());
</script>

example1

<script>
(function () {
  var konami = new Konami();
  var foo = function () {
    console.log("bar"):
  };
  konami.init(foo);
} ());
</script>

example2(匿名関数)

<script>
(function () {
  var konami = new Konami();
  konami.init(function () {
    console.log("bar");
  });
} ());
</script>

また、newする際にKonamiオブジェクトの引数にキーの配列を指定することで、トリガーとなるオリジナルのコマンドを設定することも可能です。(Konamiコマンドではないコマンドを指定可能)

example3 (コマンドに「bals」を指定)

<script>
(function () {
  var konami = new Konami([66, 65, 76, 83]);
  konami.init(function () {
    alert("bals");
  });
} ());
</script>
