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 🙏

Readme

htt-loader

it's a dynamic js loader for webpack

usage

for webPack

{
  loader: 'htt-loader',
  options: {
    lazy: true,
    name: 'xx',
    regExp: 'abc/xx/(.*)/',
  }
}

由于实际上使用的还是promise异步函数,所以你应该还需要一个js着陆的Component,拿react来说的话例如以下这个简单的栗子:

import { Component } from 'react';

// 这是一个demo给被loader封装过的js的React.Component
class Bundle extends Component {
  state = {
    // short for "module" but that's a keyword in js, so "mod"
    mod: null
  }

  componentWillMount() {
    this.load(this.props)
  }

  componentWillReceiveProps(nextProps) {
    if (nextProps.load !== this.props.load) {
      this.load(nextProps)
    }
  }
  // 加载
  load = (props) => {
    props.load(this.cb)();
  }
  // 回调
  cb = (_import) => {
    this.setState({ mod: _import.default || null });
  }

  render() {
    const Mod = this.state.mod;
    return this.state.mod ? <Mod /> : null
  }
}

caution

使用的时候必须遵守的规则

  • 需要在.babelrc加入syntax-dynamic-import规则用来开启动态加载语法
