[WAVE + Webpack] How to edit the configuration file

Hello everyone,

It's me again for a new question! I think this one is a bit silly, but I really need to ask it.

I'm trying to incorporate a TUS upload system (for Cloudflare Stream) and I have to use the fs module. However, I get the following error:

Module not found: Error: Can't resolve 'fs' in '\resources\views\themes\tailwind\assets\js'

This seems to be a very common error as this publication shows: https://github.com/webpack-contrib/css-loader/issues/447

The solution would be to add the following code to the webpack.config.js file:

node: {
    fs: 'empty
}

However, the configuration file webpack.config.js is located in node_modules/laravel-mix/setup/webpack.config.js.

So I have two questions:

• If I modify a file in node_modules, it will be deleted at each update or new installation. This doesn't seem to be a solution to me.
• The Wave webpack.config.js file does not look at all like the webpack I am used to as indicated in the documentation: https://webpack.js.org/configuration/

What am I missing here?

Just for information, here is my code:

var fs = require("fs"); // error
var tus = require("tus-js-client"); // ok
