javascript - 如何将客户端 HTML 导入 Gatsby/React？

标签 javascript node.js reactjs components gatsby

我是一个 react 菜鸟和自学成才的人，所以我确信我在做一些愚蠢的事情。我正在尝试将一小部分客户端渲染的 html 制作成我的 Gatsby 站点中的组件。已经为此奋斗了4天。我迫切希望将这个 Vue 组件放到我的 Gatsby 站点中。
这是我的组件的代码:

import React, { Component } from "react"
import { Helmet } from "react-helmet"
import DemoHTML from '../../static/demo.html');


class Model extends Component {
  componentDidMount() {

    // set up and use external package as needed

    const Mount = React.createClass({
        render: function(){
          return (
            <section contentEditable='false' dangerouslySetInnerHTML={{ __html: DemoHTML }} />
          );
        }
      });
  }
  render(props, Mount) {
    return (
      <React.Fragment>

<Helmet>

<script type="text/javascript" src="https://unpkg.com/vue"></script>
<script type="text/javascript" src="https://unpkg.com/zircle"></script></Helmet>
<Mount></Mount>
      </React.Fragment>
    )
  }
}


export default Model;
然后，这是导入的 HTML:


                    

<div id="app">
  <z-canvas :views='$options.components'>
  </z-canvas>
</div>

    <script>

const one = [
    template: `
    <z-view style="border-color: #8F6AFA; font-family: 'Montserrat', sans-serif; font-weight: bold; color: #ffffff; border-width: 1px; background-image: linear-gradient(90deg, #292929 2.11%, #000000 104.85%)" />
` ]
<!---  truncated tested working content for readability  -->


  

    new Vue({
      el: 'app',
      components: {
        one
      },
      mounted () {
        this.$zircle.setView('one')
      }

    })
</script>
最后，这是我在控制台和页面上的错误...
页面错误:

One unhandled runtime error found in your files. See the list below to fix it:


Error in function createFiberFromTypeAndProps in ./node_modules/react-dom/cjs/react-dom.development.js:25058
Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of `Model`.

  25059 |             }
  25060 |           }
需要注意的是，HTML 页面本身可以完美呈现。
谢谢!

更新
我已经对 ESM 进行了建议的更新(并且在问题中也进行了更新。我想与大家分享一件事，以防值得考虑。这个脚本必须在客户端呈现的原因是它是一个 vue 库。(见 Zircle.github.io)
如果一切都加载到客户端，我不明白为什么这会是一个问题。但是，仅供引用。

最佳答案

让它工作的第一步是添加对 HTML 模块的支持。 Gatsby 无法立即识别它们。
安装 html-loader使用:

$ npm i -D html-loader
在 gatsby-node.js 
exports.onCreateWebpackConfig = ({
  actions,
}) => {
  actions.setWebpackConfig({
    module: {
      rules: [
        {
          test: /\.html$/,
          loader: require.resolve('html-loader'),
          options: {
            minimize: false,
          },
        },
      ],
    },
  })
}
还要确保你没有修复 ESM 导入和 commonjs require()。坚持静态 ESM 导入/导出。因此，正如已经建议的那样，删除 require() 调用并使用导入来获取 ../../static/demo.html 的 HTML 内容.
import DemoHtml from '../../static/demo.html';
无法预见您可能会遇到哪些其他问题，但请尝试上述方法并报告。
