Excluding features not reducing bundle size

[esbie]

Hello!

No matter how many features I try to include/exclude, my monaco bundle size remains the same. I'm wondering if it's because I'm using cacheGroups to create a separate monaco bundle?

    splitChunks: {
      cacheGroups: {
        monaco: {
          test: /[\\/]node_modules[\\/]monaco-editor/,
          name: "mc-monaco",
          chunks: "all",
          priority: 1,
        },

Let me know if I'm missing something obvious, thanks!

@esbie How do you import the editor in your files?

You would need to use

import * as monaco from 'monaco-editor/esm/vs/editor/editor.api.js';

instead of

import * as monaco from 'monaco-editor';

Oh my goodness that was it! That was the issue, changing the import fixed it. Thanks!
