Over the weekend, I converted an app from JS + Create React App to Typescript + Parcel v2.

The typescript tooling was extremely simple to setup with only a few added packages... until I had to setup eslint. That's when I had to install a half dozen plugins, adapters, parsers, etc like you said.

Granted, the linked eslint rewrite seems to have plans to make the typescript linting tooling simpler. However, I might end up switching to Rome in the meantime just for simpler dependency management.
