Load binary file into an ArrayBuffer using webpack

Question

In the browser, I am trying to load a binary file (loaded using webpack, not via HTTP call) into an ArrayBuffer (which will then be parsed using TypedArrays). I am trying to use webpack asset Modules to pack the binary file with the rest of the browser files, but I haven't found a way to extract that file inside the browser code and construct an ArrayBuffer from it.

I am specifying the packing as follows:

module.exports = {
    publicPath: '/some/path/',
    configureWebpack: {
      module: {
        rules: [
          {
            test: /\.trie$/,
            type: 'asset/inline',
              generator: {
                dataUrl: content => content
            }
          },
        ],
      },
    }
  }

and then in my typescript file I am 'loading' the content:

 const content = require('./50k.trie');

The Chrome debugger tells me that content is of type 'Buffer' (I thought that as a Node.js data type, not a browser data type):

but from here I haven't found a way to construct/load/create an ArrayBuffer.

Do I need to use a different asset type?
