My chord-phrase.ts is very small now that I have refactored out several classes into the HandChord and it's dependencies.

This is my chord-phrase.ts:

import { HandChord } from "./HandChord";

document.addEventListener("DOMContentLoaded", () => {
  const handChord = new HandChord();
  handChord.updateTimerDisplay(handChord);
});

When the site is built it produces this chord-phrase.js

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const HandChord_1 = require("./HandChord");
document.addEventListener("DOMContentLoaded", () => {
  const handChord = new HandChord_1.HandChord();
  handChord.updateTimerDisplay(handChord);
});
//# sourceMappingURL=chord-phrase.js.map

Which shows an error in the DevTools:

chord-phrase.js:2  
Uncaught ReferenceError: exports is not defined
    at chord-phrase.js:2:23
(anonymous)@chord-phrase.js:2

The error you're seeing in the DevTools is likely because the compiled JavaScript is using CommonJS module syntax (exports and require), which is not natively supported in the browser. Browsers natively support ES Modules, which use import and export statements.

To fix this issue, you need to configure your TypeScript compiler to output ES Modules instead of CommonJS modules. This can be done by setting the module option in your tsconfig.json file to "es2020", "es6", or any other ES module format that is appropriate for the browsers you are targeting.

Here's what you might add or change in your tsconfig.json:

{
  "compilerOptions": {
    "module": "es2020",
    "target": "es6",
    // ... other options
  }
  // ... potentially other config settings
}

After making this change, recompile your TypeScript files. The output should now use ES Modules, which should eliminate the error you're seeing in the browser.

I switched it to

"module": "es2020",
"target": "es6"

and now I get:

import { HandChord } from "./HandChord";
document.addEventListener("DOMContentLoaded", () => {
  const handChord = new HandChord();
  handChord.updateTimerDisplay(handChord);
});

Which throws this:

Uncaught SyntaxError: Cannot use import statement outside a module (at chord-phrase.js:1:1)

The error message indicates that the browser is not recognizing the import statement because the script is not being executed as a module. To resolve this, you need to specify that the script is a module by using the type="module" attribute in the <script> tag that loads your JavaScript file.

Update the script tag in your HTML to include the type="module" attribute like this:

<script type="module" src="path/to/your/chord-phrase.js"></script>

This tells the browser to treat the script as an ES module, which allows the use of import and export statements. Make sure to replace path/to/your/chord-phrase.js with the actual path to your JavaScript file.
