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 🙏

@ttk/micro-frontend-react

提供应用qiankun微前端的react组件及相关生命周期API给TTK工程使用的依赖库

1.安装

npm install -s @ttk/micro-frontend-react qiankun

yarn add @ttk/micro-frontend-react qiankun

2.API

2.1 mfApp

主工程加载单例子应用的组件,使用方式:

2.1.1 ttk json工程

  • component/index.js引入组件,
export { mfApp as MFApp } from '@ttk/micro-frontend-react'
  • app详见本工程ttk-json-demo/ttk-edf-app-micro-frontend

2.1.2 组件参数

  • name: 子工程打包时output.library输出名称(一般可取package.json里的name),libraryTarget需要umd
  • entry: 子应用访问url,
  • startAppName:子应用指定的appName
  • params: 父应用传给子应用的参数
  • callbacks: 父应用传给子应用的回调
  • restoreState:子应用unmount后,重新mount时,父应用传给子应用用于恢复的state
  • onSaveState:父应用传给子应用的回调onSaveState,子应用unmount时,执行onSaveState,保存state到父应用
  • renderLoading: 子应用加载过程中显示loading组件,不传不显示
  • renderError: 子应用显示错误信息的组件,不传使用默认的

2.2 lifecycle

提供给@ttk/react框架(v4版本),作为微前端子应用工程的生命周期

import { lifecycle } from '@ttk/micro-frontend-react';
import { config as appLoaderConfig, start, render } from '@ttk/app-loader'
import { targetDomId, startAppName } from './constant'
import pack from '../package.json';
const { name: packageName } = pack;

/**
 * single-SPA生命周期钩子,只会在微应用初始化的时候调用一次,下次微应用重新进入时会直接调用 mount 钩子,不会再重复触发 bootstrap。
 * 通常我们可以在这里做一些全局变量的初始化,比如不会在 unmount 阶段被销毁的应用级别的缓存等。
 */
export async function bootstrap(props) {
    lifecycle.bootstrap(Object.assign({ targetDomId, packageName, startAppName }, props));
    let { apps, init } = await import(/* webpackPreload: true */ './apps/index');
    // appLoader配置
    await appLoaderConfig(init({ apps }));
}

/**
 * single-SPA生命周期钩子,应用每次进入都会调用 mount 方法,通常我们在这里触发应用的渲染方法
 */
export async function mount(props = {}) {
    lifecycle.mount(Object.assign({ targetDomId, packageName, startAppName , render: start }, props))
}

/**
 * single-SPA生命周期钩子,应用每次 切出/卸载 会调用的方法,通常在这里我们会卸载微应用的应用实例
 */
export async function unmount(props) {
    lifecycle.unmount(Object.assign({ targetDomId, packageName, startAppName , state: window.reduxStore.getState() }, props));
}

/**
 * single-SPA可选生命周期钩子,仅使用 loadMicroApp 方式加载微应用时生效
 */
export async function update(props) {
    lifecycle.update(Object.assign({ targetDomId, packageName, startAppName , render }, props));
}
  • targetDomId为加载子应用容器元素的id,例如,应用容器元素为<div id="app"></div>,targetDomId为app
  • startAppName为子应用指定的appName
  • @ttk/app-loader的start, render分别为初始mount和update更新时的组件
  • unmount生命周期中的参数state,传入全局state,用于获取startAppName的state,传给主工程进行保存
