Leveraging Global Variables and Functions with Webpack and TypeScript

I have been utilizing Webpack in conjunction with TypeScript, HTML, and SCSS to develop a project. My goal is to create a single page application that incorporates a router located within the root folder of the project /framework/, with all my source code residing in the /src/ directory. However, I encountered an issue when navigating into subfolders (e.g. /src/pages/home/index.ts) where I found myself needing to repetitively use

import * as framework from '../../../framework/';
in every page. Despite seeking solutions on platforms like StackOverflow, none of them have proven successful so far. Here are some attempts:

// File: /webpack.dev.config.js

resolve: {
        alias: {
            framework: path.resolve(__dirname, './framework') // <-- When you build or restart dev-server, you'll get an error if the path to your utils.js file is incorrect.
        }
    },
    devtool: 'inline-source-map',
    plugins: [
        new HtmlWebpackPlugin(),
        new webpack.ProvidePlugin({
            framework: [path.resolve(path.join(__dirname, 'framework')), 'framework']
        })
    ],

However, none of these worked. I also experimented with the following:

// File: /src/index.ts

const path = require('path');
global.fw = String(path.resolve(__dirname, "framework"));

In TypeScript, this approach threw me an error stating

fs: Element implicitly has an 'any' type because type 'typeof globalThis' has no index signature.ts(7017)

Is there a way for me to simplify my import statements to something like

import * as framework from '@framework';
or
import * as framework from '@framework/main';
, or perhaps utilize a global variable for ease of access? Any guidance on this matter would be greatly appreciated! Thank you.
