如何在heroku上使用webpack后使用webpack部署angularjs应用程序

const path = require('path');

module.exports = {
  entry: './app.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env']
          }
        }
      }
    ]
  }
};

web: npm start

{
  "name": "your-app-name",
  "version": "1.0.0",
  "scripts": {
    "start": "webpack && node server.js"
  },
  "dependencies": {
    "express": "^4.17.1"
  },
  "devDependencies": {
    "@babel/core": "^7.15.5",
    "@babel/preset-env": "^7.15.6",
    "babel-loader": "^8.2.2",
    "webpack": "^5.52.1",
    "webpack-cli": "^4.8.0"
  }
}

const express = require('express');
const app = express();
const path = require('path');

app.use(express.static(path.join(__dirname, 'dist')));

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname, 'dist', 'index.html'));
});

const port = process.env.PORT || 3000;
app.listen(port, () => {
  console.log(`App is running on port ${port}`);
});

npm install

npm start
