我正在尝试为我的博客开发一个新功能,即用于撰写文章的 Markdown 编辑器。

我选择@tailwindcss/typographymarkdown-it来做到这一点,所以这是我的全部依赖项:

包.json

{
 "dependencies": {
    "firebase": "^9.0.0-beta.7",
    "markdown-it": "^12.2.0",
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-router-dom": "^5.2.0"
  },
  "devDependencies": {
    "@babel/core": "^7.15.0",
    "@babel/preset-env": "^7.15.0",
    "@babel/preset-react": "^7.14.5",
    "@tailwindcss/typography": "^0.4.1",
    "autoprefixer": "^10.3.2",
    "babel-loader": "^8.2.2",
    "css-loader": "^6.2.0",
    "dotenv-webpack": "^7.0.3",
    "html-webpack-plugin": "^5.3.2",
    "postcss": "^8.3.6",
    "postcss-cli": "^8.3.1",
    "postcss-loader": "^6.1.1",
    "style-loader": "^3.2.1",
    "tailwindcss": "^2.2.7",
    "webpack": "^5.51.1",
    "webpack-cli": "^4.8.0",
    "webpack-dev-server": "^4.0.0"
  }
}

下面的代码是这个功能的组件,包括一个编辑区和一个预览区。但是,它没有用。

当我运行此代码时,它会像这样呈现出来,而无需排版<h1>标签。

但是,如果我替换md.render(markdown)<h1>hello</h1>markdown-it 的渲染结果),它似乎“工作”,看起来像这样

编辑器.jsx
import React, { useState } from "react";
const md = require("markdown-it")('commonmark');


const Editor = () => {
  const [markdown, setMarkdown] = useState("# hello");
  const onTextChange = (e) => {
    setMarkdown(e.target.value);
  }

  return (
    <div>
      <form>
        <textarea onChange={(e) => onTextChange(e)}>
          {markdown}
        </textarea>
      </form>

      <div id="preview" className="prose">
        {md.render(markdown)} {/* <h1>hello</h1> */}
      </div>

    </div>
  )
}

export default Editor;

为什么会发生这些事情?以及如何使其符合预期?

使用react-markdown代替markdown-it

这是一个例子:

import ReactMarkdown from "react-markdown";

<div className="prose">
    <ReactMarkdown>{markdown}</ReactMarkdown>
</div>

它会将提供的内容呈现为页面中的 DOM,并Tailwind/typography完美地设置这些元素的样式。
