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 🙏

v0.2.0-alpha.0

Published

A window system for web applications.

Readme

WindowSystem

Webページ上で複数のウィンドウを作成・管理するTypeScriptライブラリです。

機能

  • 複数ウィンドウの作成、変更、削除、状態取得
  • Pointer Eventsによる移動と8方向リサイズ
  • アクティブウィンドウとz-indexの自動管理
  • URLを読み込むiframe
  • 最小化、最大化、非表示とJSONスナップショット

インストールとビルド

npm install
npm run build

ブラウザで利用する場合はJavaScriptとCSSの両方を読み込みます。

import { WindowManager } from "@donneko/window-system";
import "@donneko/window-system/window-style.css";

const windows = new WindowManager();

const id = windows.createWindow({
    title: "管理画面",
    contentUrl: "/admin/index.html",
    x: 40,
    y: 40,
    width: 640,
    height: 420,
    minWidth: 320,
    minHeight: 180,
});

windows.updateWindow(id, {
    title: "更新済み",
    status: { isMaximized: true },
});

配置先を指定する場合、その要素には通常 position: relative と表示領域のサイズを設定します。

const windows = new WindowManager({
    container: document.querySelector<HTMLElement>("#desktop")!,
});

状態の保存と復元

WindowSnapshot はDOMを含まないため、そのままJSONへ保存できます。

localStorage.setItem("windows", JSON.stringify(windows.getWindows()));

const snapshots = JSON.parse(localStorage.getItem("windows") ?? "[]");
for (const snapshot of snapshots) {
    windows.createWindow(snapshot);
}

保存先の管理は利用側の責任です。URLのページがiframe表示を拒否する場合は、そのページのCSPまたは X-Frame-Options に従います。
