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 🙏

Taro plugin for injecting MobX polyfills in WeChat Mini Programs

Readme

@tarojs/plugin-mobx-polyfill

一个为 Taro 微信小程序项目提供 MobX polyfills 的插件,解决小程序环境中缺失的 ES6+ 特性问题。

问题背景

在微信小程序中使用 MobX 时,会遇到以下问题:

  • Symbol 未定义
  • Map 未定义
  • Set 未定义

这些 ES6+ 特性在小程序环境中不可用,导致 MobX 无法正常运行。

解决方案

本插件通过在 Taro 构建过程中自动注入 polyfill 代码,为小程序环境添加缺失的 ES6+ 特性支持。

安装

npm install @tarojs/plugin-mobx-polyfill --save-dev

或使用 yarn:

yarn add @tarojs/plugin-mobx-polyfill --dev

使用方法

config/index.js 中配置插件:

const config = {
  // ... 其他配置
  plugins: ['@tarojs/plugin-mobx-polyfill']
}

工作原理

插件会在 Taro 构建过程中自动执行以下操作:

  1. 通过 onSetupClose 钩子注入运行时代码
  2. 在用户 app.js 执行前自动引入 polyfill
  3. 为全局对象添加 SymbolMapSet 支持

注入的 polyfill 代码:

window.Symbol = Symbol
window.Map = Map  
window.Set = Set

    ├── index.js          # 插件主代码
