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 🙏

wangEditor 公式

介绍

wangEditor 公式插件,使用 LateX 语法。

安装

yarn add katex
yarn add @wangeditor/plugin-formula

使用

注册到编辑器

import { Boot, IEditorConfig, IToolbarConfig } from '@wangeditor/editor'
import formulaModule from '@wangeditor/plugin-formula'

// 注册。要在创建编辑器之前注册,且只能注册一次,不可重复注册。
Boot.registerModule(formulaModule)

配置

// 编辑器配置
const editorConfig: Partial<IEditorConfig> = {
  // 选中公式时的悬浮菜单
  hoverbarKeys: {
    formula: {
      menuKeys: ['editFormula'], // “编辑公式”菜单
    },
    text: {
      menuKeys: ['textToFormula'],  // “公式转换”菜单
    }
  },

  // 其他...
}

// 工具栏配置
const toolbarConfig: Partial<IToolbarConfig> = {
  insertKeys: {
    index: 0,
    keys: [
      'insertFormula', // “插入公式”菜单
      // 'editFormula' // “编辑公式”菜单
    ],
  },

  // 其他...
}

然后创建编辑器和工具栏,会用到 editorConfigtoolbarConfig 。具体查看 wangEditor 文档。

显示 HTML

公式获取的 HTML 格式如下

<span data-w-e-type="formula" data-value="c = \\pm\\sqrt{a^2 + b^2}"></span>

其中 data-value 就是 LateX 格式的值,可使用第三方工具把 <span> 渲染成公式卡片,如 KateX

其他

fork 自 wangEditor-plugin-formula,由于作者因时间原因暂停维护,故 fork 下来在原有基础上增加一些功能,后续修改不支持 i18n 多语言。
