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 🙏

@ali/babel-plugin-rx-components-ondemand

此插件可以在 rx 项目构建时自动去除未能在代码中使用的 import 组件

  • 使用方法:

    • 安装插件
      tnpm install @ali/babel-plugin-rx-components-ondemand --save-dev
    • 在 .babelrc 或者 webpack 的 babel loader 中添加该组件的引用
      {
        "plugins": [['@ali/babel-plugin-rx-components-ondemand']]
      }
    • 现在 build 的时候就会分析代码中引用的组件是否真的被调用了,如果调用的话才会被打包
  • 使用前后对比:

    • 使用前打包信息(全量打包):
    Time: 3002ms
                   Asset    Size  Chunks       Chunk Names
        p/index/index.js  124 kB       0       p/index/index
    p/index/index.js.map  128 kB       0       p/index/index
    webpack: bundle is now VALID.
    • 若使用本插件并在项目中使用View,Link,Text时(按需打包):
    import {View, Text , Image ,Link, TextInput, Button ,ScrollView } from '@ali/rx-components';
    
    Time: 1675ms
                   Asset     Size  Chunks       Chunk Names
        p/index/index.js  87.7 kB       0       p/index/index
    p/index/index.js.map  96.9 kB       0       p/index/index
    webpack: bundle is now VALID.

    Image, TextInput, Button, ScrollView 引入但未使用的组件也不会进行打包
