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 🙏

react-lazyload-loader(v1.0.0)


该webpack loader主要目的是简化react开发过重中,异步组件加载问题,简化使用和操作。提升代码分离和打包机制,优化代码结构。 作者:老黑,群:126274877

功能及使用

  • 异步分离和切割react组件;
  • 依赖第三方组件 react-loadable(npm i react-loadable --save);
  • 可配置等待渲染组件;
    $ npm i react-lazyload-loader -D

webpack中使用方法

{
    test: /\.js$/,
    exclude: /node_modules/,
    use: [
        {
            loader: 'babel-loader',
            options: {
                plugins: ['react-hot-loader/babel']
            }
        },
        {
            loader: ['react-lazyload-loader'],
            options: {
                loading: {
                    name: 'ComponentLoading',
                    path: 'components'
                }
            }
        }
    ]
}

###业务代码中使用


import React from 'react';
import {Route, Switch, Redirect} from 'react-router-dom';

export default ({match}) => {
    return (
        <Switch>
            <Route path={`${match.url}/dashboard`} component={require('lazy|./pages/dashboard')}/>
            <Route path={`${match.url}/widgets`} component={require('lazy|./pages/widgets')}/>
            <Route path={`${match.url}/profile`} component={require('lazy|./pages/profile')}/>
            <Route component={() => (
                <Redirect push to="/app/dashboard"/>
            )}/>
        </Switch>
    )
};

需要在引入的组件路径前加 【lazy|】

中间等待组件的使用

tips:异步加载组件过程中,在弱网环境下,异步模块js加载失败或者加载缓慢,需要有等待状态和提示状态,来提醒前端页面;webpack loader options中有loading配置项;

参数 name 必须:等待组件名称; 参数 path 必须:等待组件存放路径; 组件写法

import React, {Component} from "react";

export default ({isLoading, error}) => {
    if (isLoading) {
        return <div>😆~~,Component is Loading.</div>;
    } else if (error) {
        return <div>😢~~,Sorry, there was a problem loading the page.</div>;
    } else {
        return <div>👽~~ <div/>;
    }
};

如:

loading: {
    name: 'ComponentLoading',
    path: 'components'
}

编译结果:import {ComponentLoading} from 'components';

path路径是相对你当前使用lazy组件加载的目录;或者node_modules,作者使用的是路径别名
