reactjs - 空项目中 forge-dataviz-iot-react-components 的 Autodesk React Forge 问题

Question

如果安装官方npm package , 它有效。

但是根据official documentation并简单地将 import { Viewer } from "forge-dataviz-iot-react-components" (如 this 示例)包含在一个空的新 React 项目中(使用 npx create-react- app) 你会得到这个错误:

./node_modules/forge-dataviz-iot-react-components/client/components/BasicTree.jsx 107:16
Module parse failed: Unexpected token (107:16)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
|         if (node.children.length > 0) {
|             return (
>                 <TreeItem
|                     id={`tree-node-${node.id}`}
|                     key={node.id}

我需要在 webpack 上添加哪个 loader 才能避免这个错误？

Answer 1

无法包含包 https://www.npmjs.com/package/forge-dataviz-iot-react-components在使用 npx create-react-app 制作的 React 项目中(希望 Autodesk 能尽快解决这个问题)。

您需要分两部分编辑 /node_modules/react-scripts/config/webpack.config.js:

一行关于PIXI

...
      alias: {
        'PIXI': "pixi.js/",

        // Support React Native Web
        // https://www.smashingmagazine.com/2016/08/a-glimpse-into-the-future-with-react-native-for-web/
        'react-native': 'react-native-web',
        // Allows for better profiling with ReactDevTools
        ...(isEnvProductionProfile && {
          'react-dom$': 'react-dom/profiling',
          'scheduler/tracing': 'scheduler/tracing-profiling',
        }),
        ...(modules.webpackAliases || {}),
      },
...

还有关于/forge-dataviz-iot-react-component的另一部分

...
    module: {
      strictExportPresence: true,
      rules: [
        // Disable require.ensure as it's not a standard language feature.
        { parser: { requireEnsure: false } },
        {
          // "oneOf" will traverse all following loaders until one will
          // match the requirements. When no loader matches it will fall
          // back to the "file" loader at the end of the loader list.
          oneOf: [


            {
              test: /forge-dataviz-iot-react-component.*.jsx?$/,
              use: [
                {
                  loader: require.resolve('babel-loader'),
                  options: {
                    presets: ["@babel/react", ["@babel/env", { "targets": "defaults" }]],
                    plugins: ["@babel/plugin-transform-spread"]
                  }
                },
              ],
              exclude: path.resolve(__dirname, "node_modules", "forge-dataviz-iot-react-components", "node_modules"),
            },



            // TODO: Merge this config once `image/avif` is in the mime-db
            // https://github.com/jshttp/mime-db
            {
              test: [/\.avif$/],
              loader: require.resolve('url-loader'),
              options: {
                limit: imageInlineSizeLimit,
                mimetype: 'image/avif',
                name: 'static/media/[name].[hash:8].[ext]',
              },
            },
...

在那之后 /node_modules/forge-dataviz-iot-react-components/client/components/Viewer.jsx 你会得到关于未定义的 Autodesk 变量的错误 easily fixable changing Autodesk 与 window.Autodesk。

虽然您不会看到任何其他错误，但该包将无法运行。
