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 🙏

Napacitor App 插件(应用生命周期/退出/语言/启动链接,映射 MAUI 应用生命周期)

Readme

@napacitor/app

应用生命周期插件(与 @capacitor/app 对应)。

用法

import { App } from '@napacitor/app';

const { isActive } = await App.getState();
const { value: language } = await App.getAppLanguage(); // 'zh-CN'

App.addListener('appStateChange', ({ isActive }) => console.log('active:', isActive));
App.addListener('pause', () => console.log('进入后台'));
App.addListener('resume', () => console.log('回到前台'));
App.addListener('appUrlOpen', ({ url }) => console.log('深度链接:', url));
App.addListener('backButton', ({ canGoBack }) => console.log('返回键'));

const { url } = await App.getLaunchUrl();

结构

  • src/ —— TypeScript 源码(index / definitions / web)
  • dist/ —— 构建产物(CJS + d.ts,已提交)
  • maui/ —— .NET MAUI C# 实现(程序集 Napacitor.App,运行时反射自动发现)

原生实现映射:Window 生命周期事件 Resumed / Stopped / Backgrounding (appStateChange / pause / resume)、Application.Quit(exitApp)、 CultureInfo.CurrentUICulture(getAppLanguage)。首个生命周期监听器注册(或首次 getState)后惰性挂接主 Window。

与 Capacitor 的差异

  • exitApp:映射 Application.Quit,仅 Windows/macOS 有原生语义;Android/iOS 系统 不鼓励程序化退出(HIG/Play 政策),如需强退需宿主平台代码;

  • appUrlOpen / getLaunchUrl(深度链接):MAUI 无跨平台的 App Link 事件,宿主需 ①注册 URL scheme,②在 App.xaml.cs 转发:

    protected override void OnAppLinkRequestReceived(Uri uri)
    {
        base.OnAppLinkRequestReceived(uri);
        Napacitor.Plugins.App.AppPlugin.NotifyAppLink(uri);
    }

    URL scheme 注册:Android 在 AndroidManifest.xml 的 MainActivity 加 <intent-filter>(<data android:scheme="your-scheme" />);iOS 在 Info.plist 加 CFBundleURLTypes;Windows 打包应用在 Package.appxmanifest 声明协议;

  • backButton(Android):宿主在 MainActivity 重写返回键并转发:

    public override void OnBackPressed()
    {
        if (!AppPlugin.NotifyBackButton())
        {
            base.OnBackPressed(); // 无 JS 监听器时走默认行为
        }
    }

    NotifyBackButton 返回 true 表示 JS 已监听(宿主应拦截本次返回键);

  • appRestoredResult / minimizeApp / edgeGesture:暂未实现。
