Unexpected token error due to character sequence disruption from Webpack

Although the title may not be very descriptive, I am currently experimenting with the 'xstate' library and running into an issue with an 'Unexpected token' error in my build result.

Here is a snippet from my webpack configuration file (webpack.config.js):

var WebpackBuildNotifierPlugin = require('webpack-build-notifier');

var webpackConfig = { 
    // Configuration details omitted for brevity
};


module.exports = [
    webpackConfig
];

Upon inspecting the generated bundle.js file after building the code, I noticed a section that appears to be triggering the 'Unexpected token' error:

u
/* WEBPACK VAR INJECTION */}.call(this, __webpack_require__(/*! ./../../webpack/buildin/global.js */ "./node_modules/webpack/buildin/global.js")))ndefined

The 'xstate' library is being imported and utilized in the following manner within my project:

import * as React from 'react';
import { Machine, interpret } from 'xstate';

// Code snippet showcasing usage of xstate library

typescript webpack xstate

Figuring out all the setup variables can be a challenge, but here is what I did to troubleshoot and solve a similar issue:

First, I followed a guide on setting up TypeScript with React and Webpack which you can find here.

After ensuring everything was set up properly, I replaced the content of a component with the code provided in the question. The resulting "working" component looked like this:

import * as React from 'react';
import { Machine, interpret } from 'xstate';

// Rest of the code example...

I used a basic machine example from the xstate repository as the basis for appRootMachine, keeping the implementation as close to your original code as possible.

Subsequently, I updated the webpack configuration file with the provided settings, installed necessary dependencies like awesome-typescript-loader and webpack-build-notifier, and made relevant changes such as updating the entry point and script tag path in index.html.

Following these steps, everything seemed to work smoothly on my end. Hopefully, these suggestions help you resolve any issues you are facing with your project setup.

Additionally, I recommend considering the @xstate/react package for future use with xstate and React. The package offers useful examples that may provide further insights into resolving your specific problem.
