Encountering continuous failures when attempting to add babel-loader for parsing JS files due to various issues

Issue with Vue Project

In our application, we encountered a problem where one of the indirect dependencies had JS files that were causing Webpack to fail during parsing. To resolve this issue, I integrated a babel-loader.

const webpack = require("webpack");
 
module.exports = {
    entry: './src/index.ts',
    target: 'node',
    mode: 'production',
    module: {
        rules: [
            { 
                test: /\.(ts|tsx)$/, 
                loader: 'ts-loader',
            },
            { 
                test: /\.(js|jsx)$/, 
                loader: 'babel-loader',
            }
        ]
    },
    plugins: [
        new webpack.IgnorePlugin(/vertx/),
    ],
    resolve: {
        extensions: ['.js', '.ts']
    },
    output: {
        filename: 'index.js',
        path: `${__dirname}/dist`, 
        library: 'stormcv-website-client', 
        libraryTarget: 'umd'
    }
}

.babelrc

{
    "presets": ["react", "es2015", "stage-0"]
}

Package.json:

{
  "name": "stormcv-website-client",
  "version": "1.0.0",
  "description": "client",
  "homepage": "",
  "license": "UNLICENSED",
  "main": "dist/index.js",
  "types": "dist/index.d.ts",
  "files": [
    "dist"
  ],
  "browserquot;: {
    "vertx": false
  },
  "repository": {
    "type": "git",
  },
  "dependencies": {
    "coral-super-client": "*"
  },
  "scripts": {
    "build": "webpack",
    "clean": "rm -rf build dist node_modules package-lock.json",
    "prepublishOnly": "npm run build"
  },
  "devDependenciesquot;: {
    ...
  }
}

Despite attempts, the build process continues to fail due to various errors such as the following:

[00:02] info Rebuilding package-lock.json
...
BUILD FAILED 

or

[00:03] info Rebuilding package-lock.json
...
BUILD FAILED

I have searched for similar issues on Stack Overflow and tried the following steps:

npm cache clean --force  
rm -rf package-lock.json /node_modules    
npm install

However, I am still unable to resolve these errors. It feels like I might be overlooking something fundamental. Any suggestions?

The solution to this issue can be found in updating webpack to the latest version.

Here is a snapshot of my current webpack configuration:

const webpack = require("webpack");

module.exports = {
    entry: './src/index.ts',
    target: 'node',
    mode: 'production',
    module: {
        rules: [
            // Use ts-loader for handling files with extensions .ts, .cts, .mts, or .tsx
            { test: /\.([cm]?ts|tsx)$/, loader: "ts-loader" }
        ]
    },
    plugins: [
        new webpack.IgnorePlugin({resourceRegExp: /vertx/}),
    ],
    resolve: {
        extensions: [".ts", ".tsx", "jsx", ".js"],
        extensionAlias: {
            ".js": [".js", ".ts"],
            ".cjs": [".cjs", ".cts"],
            ".mjs": [".mjs", ".mts"]
        },
    },
    output: {
        filename: 'index.js',
        path: `${__dirname}/dist`, 
        library: 'stormcv-website-client',
        libraryTarget: 'umd'
    }
}
