My formatting is based on the airbnb-base through eslint and prettier, which depends on the eslint, eslint-config-airbnb-base, eslint-config-prettier, eslint-plugin-import, eslint-plugin-prettier and prettier devDependencies. I also have the eslint extension https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint installed that surfaces the formatting issues into the problem tab.

Maybe eslint settings should be included in the repo? Just enabled it on my end and every file has "issues", because my settings are not the same...

They already were (.eslintrc.json, .prettierrc.json).

I just realized that I didn't include a link to the Prettier extension, which I also have installed, but I feel like it's only for formatting and wouldn't have an effect on seeing issues everywhere since all of that is covered through ESLint.
