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 🙏

queryfast

v2.1.0

Published

A tiny, fast, and reactive DOM manipulation library.

Readme

🚀 QueryFast v2.0

「Q は DOM カーソルであり、el は DOM を生む唯一の構文である。」

QueryFast は、超軽量・高速・直観的な DOM 操作ライブラリです。 仮想 DOM を使わず、ブラウザのネイティブ機能を最大限に活かした「最小・最速」の UI 開発体験を提供します。

🌟 特徴

  • Zero Overhead: 仮想 DOM なし。直接 DOM を操作するため、極めて高速です。
  • 🧱 DOM Cursor Philosophy: Q は常に DOM を指すカーソル。迷うことなく操作できます。
  • 🏗 Single Syntax: el() だけで要素生成もコンポーネント呼び出しも完結します。
  • 🔄 Simple Reactive: 組み込みの状態管理で、値の変化を即座に UI に反映。
  • 📦 Ultra Light: 依存関係ゼロ。単一の HTML ファイルへの埋め込みにも最適です。

🛠 インストール

npm install queryfast

🚀 クイックスタート (v2.0)

import { Q } from 'queryfast';

// 1. Q で DOM カーソルを取得
const app = Q("#app");

// 2. el() で要素を生成して append
const counter = app.el("div.counter");

// 3. リアクティブな状態
const count = Q.state(0);

// 4. コンポーネントの定義
function countDisplay(parent, state) {
  return parent.el("p")
    .bind(state, v => `Count: ${v}`, 'text');
}

// 5. コンポーネントの呼び出しとイベント
counter.el(countDisplay, count);
counter.el("btn#inc").text("+").on("click", () => count.value++);
