Here are few important notes:

This repository is a fork of https://github.com/glook/webpack-typescript-react (base react + webpack 5 boilerplate, see below)

This code is not for production use and only runs on Firefox due to SharedWorker and WebWorker specific features browser support.

I honestly just had so much fun playing with those that I could not resist going all in :)

For a real world application I would rely on a different setup, although less optimal probably.

Features

It shares one WebSocket connection with multiple component instances and/or tabs. No matter how many, there will always be only one connection.
It uses at most 2 WebWorkers, one for every currently displayed product.
Component updates are throttled no matter the message frequency from the WebSocket
Fully responsive

Memory usage in time

Absolutely stable

Firefox Profiler

Very lightweight on the CPU

React Profiler

dev build rendering times

Tests
SharedWorker is currently not supported in safari, but it is again under consideration (https://bugs.webkit.org/show_bug.cgi?id=149850)
SharedWorker cannot spin up WebWorker in Chrome
I used HTML tables and SVG as they are accessible and in theory the right tool for the job.
Naming of CSS classes and variables in general
...many more, software is a never ending journey :D

Webpack 5 boilerplate with support of most common loaders and modules:

babel
typescript (using ForkTsCheckerWebpack )
sass, less, css modules with automatic typescript declaration
with react support (also with react-refresh)
esLint
prettier (with import sorting using prettier-plugin-import-sort, import-sort-style-module-and-prefix)
webpack dev server (proxy support is also available)
importing svg as react components using @svgr/webpack
postcss loader (with autoprefixer and cssnano)
husky prehooks and lint-staged
