## About The Pull Request
**Upgrades:**
- Yarn 3.0
- TypeScript 4.3
- Sass 1.37
- Required some refactoring of `/` into `math.div()` in CSS
**Dependency removals:**
- Removed ESM package, see: https://github.com/standard-things/esm/pull/902
I initially thought it was impossible to stop relying on this package, but fortunately, ES module support in Node 12+ now comes standard and I only had to convert the very few external module imports to `require()` (because Yarn PnP).
I also moved `logging.js` directly into `tgui-dev-server` package, because that's where it is used. One less internal dependency.
**Sidegrades:**
- Removed creation of a common tgui chunk, because in practice it creates unnecessary complexity (devs sometimes get a white screen due to this chunk being invalid) and doesn't really save that much data on CDN, and **definitely** doesn't make tgui load faster.
I think that is all. I tested it a bit and everything seemingly works.
