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 🙏

使用

使用 createApp/createPage/createComponent 包裹对应类型的初始化配置,让实例具备以下方法:

  • 跳转关闭:open/close
  • 事件相关:on/off/emit
  • 获取实例:getApp/getPage 兼容插件
  • 获取参数:getParams/getLaunchOptions

使用 createPlugin 包裹插件配置,让插件具备以下方法:

  • getData:获取插件数据,支持 a.b.c.d 链式获取
  • setData:设置插件数据,支持 a.b.c.d 链式设置
  • getHost:获取宿主环境(包括当前应用插件的 app/page 实例)

由于插件中不能使用 <web-view> 组件,因此插件中调用 this.open(url, { webview: true }) 会触发事件冒泡至 app,然后在 app 中打开 <web-view> 页面(pages/webview/index?url=url

跳转和事件等文档请查看 @miapp/utils@miapp/emitter

import {
  createApp,
  createPage,
  createComponent,
  createPlugin
} from "@miapp/app";

// app.js
import appConfig from './app.json';

createApp({
  mixins: [], // 全局混入
  onLaunch() {
    this.on('foo', e => console.log('app', e)); // app bar
  }
}, appConfig); // 此处要传入 appConfig,用于初始化 plugins

// page.js
createPage({
  mixins: [], // 页面混入
  onLoad() {
    this.on('foo', e => console.log('page', e)); // page bar
    console.log(this.getLaunchOptions());
  }
});

// component.js
createComponent({
  onInit() {
    this.on('foo', e => console.log('component', e)); // component bar
  },
  didMount() {
    this.emit('foo|app', 'bar'); // 冒泡 component => page => app
    this.getParams(); // 获取页面参数
    this.getLaunchOptions(); // 获取APP参数
  }
});

// plugin.js
createPlugin({
  data: {
    foo: {
      bar: 'yes'
    }
  },

  methods: {
    sayHello() {
      console.log('hello');
    },

    log() {
      this.sayHello(); // hello
      this.getData('foo.bar'); // yes
      this.getHost().app; // 当前 getApp() 获取的实例
      this.getHost().page; // 当前应用插件的页面实例
    }
  }
});

requirePlugin('plugin').setData('foo.bar'); // no

Mixins

支持对象或函数类型的混入方式

export const loading = {
  showLoading() {
    this.emit('show:loading');
  },
  hideLoading() {
    this.emit('hide:loading');
  }
}
export const mixinLoading = (target) => {
  target.showLoading = function () {
    this.emit('show:loading');
  };
  target.hideLoading = function () {
    this.emit('hide:loading');
  };
  return target;
};
