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-comment-input 使用指南

react-comment-input 是一个类似飞书输入框的 React的输入组件。 git仓库

查看详情 组件demo

自定义组件

先定义一个自定义组件的数据格式

interface UserElement {
  type:'user',
  username:string
  children: [{ text: any }]
}

/**
 * type和children属性是固定的,children是个数组里面可嵌套,但是必须要有个,
 * 一般 {text:""}默认
 */
const userNode: UserElement = {
  type: 'user',
  username: 'wzx',
  children: [{ text: 'wzx' }]
}

再定一个UserNode的自定义组件用于在输入框中显示

import { FC } from 'react'
import { RenderElementProps } from '@wzx-unreal/react-comment-input/lib/types/types'
const UserNode: FC<RenderElementProps> = (props) => {
  /**
   * 这里的children就是UserElement的children
   */
  const { attributes, element, children } = props
  const el: { username: string } = element as UserElement
  return (
    <span
      {...attributes}
      contentEditable={false}
      style={{ padding: '2px 5px', margin: '0 2px', background: 'orange' }}
    >
      {el.username}
      {children}
    </span>
  )
}
export default UserNode

接着在ReactCommentInput传入一些属性

  1. extendRenderElement这里必须传入对应的类型,以及该类型需要渲染的组件(照我的就可以)
  2. htmlToSlateConfigOptions将html转成编辑器的数据格式比如<user user-data="batman"></user>,当编辑器遇到这个html的时候会解析他,这边我是做了判断如果在<user>这个标签上有user-data属性则说明是我自定义的属性,否则就使普通的类型,这边都可以自己去写逻辑
  3. slateToDomConfigOptions将编辑器的数据格式转成html elementAttributeTransform 这个属性是用来将自定的数据格式通过这个方法转成html的数据。 elementMap 这个属性是用来将自定的数据格式的type转化为对应的html的标签这边我转为了<user></user>标签
  4. isInlineElementTypes用来标记是行内元素
  5. isVoidElementTypes"void"节点是 Slate 中的一个特殊概念,表示一个不能被编辑或只能以特殊方式编辑的节点。例如,你可能希望在编辑器中插入一个图像,这个图像是一个节点,但用户不能像编辑文本那样编辑它——它是一个"void"节
  6. theme目前支持dark|light两种,对应的是mention的弹窗样式
  <ReactCommentInput
    theme="dark"
    renderElementConfig={{
      extendRenderElement: [
        {
          type: 'user',
          renderElement: ({ children, ...rest }) => {
            return <UserNode {...rest}>{children}</UserNode>
          }
        }
      ],
    }}
    htmlToSlateConfigOptions={{
      elementTags: {
        user: (_el) => {
          if (_el) {
            const { attribs } = _el
            if (attribs['user-data']) {
              return {
                type: 'user',
                username: attribs['user-data']
              }
            }
          }
          return {
            type: 'span'
          }
        }
      }
    }}
    slateToDomConfigOptions={{
      elementAttributeTransform: ({ node, attrs }) => {
        if (node.type === 'user') {
          attrs['user-data'] = node.username
        }
        return attrs
      },
      elementMap: {
        user: 'user'
      }
    }}
  />

store 本组件提供配置存储 useReactCommentInputStore

使用方法

import { useReactCommentInputStore } from '@wzx-unreal/react-comment-input'

在预览组件<PreviewEditor/>和编辑组件<ReactCommentInput /> 里面有一些通用的配置

    const commonConfig:PreviewEditorProps = {
      isInlineElementTypes,
      isVoidElementTypes,
      isMarkableVoidElementTypes,
      value,
      className,
      style,
      htmlToSlateConfigOptions,
      slateToDomConfigOptions,
      renderElementConfig,
    }
    //你可以
  <PreviewEditor {...commonConfig} {..._others} />
  <ReactCommentInput {...commonConfig} {...others} />
  //也可以
    useEffect(() => {
      useReactCommentInputStore.setState({
        basicProps: commonConfig
      })
    }, [commonConfig])
   const basicProps=useReactCommentInputStore(state=>state.basicProps)
    if (basicProps){
      //这边需要设置完再加载,因为editor初始化的时候需要把一些参数一起配置了这样才能保证自定义组件正确
      //的渲染出来
      return (
        <>
          <PreviewEditor  {..._others} />
          <ReactCommentInput {...others} />
        </>
      )
    }

tips

当前的 <ReactCommentInput /> 是非受控模式,如果要更新里面的值请使用 ref?.actions.updateValue 这个方法
