Calling webpacked code from outside (HTML script tag)

I managed to get this working without any further webpack.config.js modifications, by simply using the import statement which i called from my main/index.js file:

import EntryPoint from './EntryPoint.js';
window.EntryPoint = EntryPoint;

For reference, here's my weback.config.js file.

Initially I tried accomplishing the same using require, however it assigned the module wrapper to window.EntryPoint as opposed to the actual class.

It seems that you want to expose the webpack bundle as a library. You can configure webpack to expose your library in the global context within a variable of your own, like EntryPoint.

I don't know TypeScript so the example uses plain JavaScript instead. But the important piece here is the webpack configuration file, and specifically the output section:

webpack.config.js

module.exports = {
  entry: './index.js',
  output: {
    path: './lib',
    filename: 'yourlib.js',
    libraryTarget: 'var',
    library: 'EntryPoint'
  }
};

index.js

module.exports = {
  run: function () {
    console.log('run from library');
  }
};

Then you will be able to access your library methods like you expect:

<script src="lib/yourlib.js"></script>
<script>
  window.onload = function () {
    EntryPoint.run();
  };
</script>
