Following instruction but cannot get amplify-ui to run

[apekkar]

I feel stupid because I cannot get this running by following the instructions
Is there some prerequisites that I am missing here or something?

First I did these:
https://docs.amplify.aws/start/getting-started/setup/q/integration/js/

I can get the web page running with npm run

Then I headed to:
https://ui.docs.amplify.aws/react/getting-started/installation
and
https://ui.docs.amplify.aws/react/getting-started/usage

and tried npm run with following error:

> [email protected] start
> webpack && webpack-dev-server --mode development

asset main.bundle.js 41.1 KiB [emitted] (name: main)
asset index.html 1.67 KiB [compared for emit] [from: index.html] [copied]

./src/app.js 223 bytes [built] [code generated] [1 error]

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

| function App() {
>   return <Button variation="primary">Hello world</Button>;
| }

webpack 5.89.0 compiled with 1 error in 55 ms

I tried adding the loader for css as instructed but no help

My webpack.config.js:

const CopyWebpackPlugin = require('copy-webpack-plugin');
const webpack = require('webpack');
const path = require('path');

module.exports = {
  mode: 'development',
  entry: './src/app.js',
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/
      },
      { 
        test: /\.css$/,
        use: [
            { loader: 'style-loader', options: { singleton: true } },
            { loader: 'css-loader', options: { importLoaders: 1, sourceMap: true } }
        ],
      }
    ]
  },
  devServer: {
    client: {
      overlay: true
    },
    hot: true,
    watchFiles: ['src/*', 'index.html']
  },
  plugins: [
    new CopyWebpackPlugin({
      patterns: ['index.html']
    }),
    new webpack.HotModuleReplacementPlugin()
  ]
};

@apekkar Unless you have previous experience, I wouldn't recommend setting up webpack by yourself (sorry that guide mislead you, we'll get that updated). The errors you are running into have to do with JSX support. Please take a look at our Next or Vite Getting Started guides:
https://ui.docs.amplify.aws/react/getting-started/usage/nextjs
https://ui.docs.amplify.aws/react/getting-started/usage/vite
Next and Vite require no additional configuration to support React.

Let us know if that helps!

We've updated the guide, so I'm closing out this ticket
