* Declare return types on functions And a very few other type related minor fixes * Minor syntax fixes * Remove unnecessary escape chars in regexes * Remove unnecessary awaits * Replace deprecated req.connection with req.socket * Replace deprecated upload with uploadOne * Remove unnecessary eslint-disable-next-line comments * Comment empty functions / catch or finally clauses * Fix irregular whitespaces * Add missing returns (null) * Remove unreachable code * A few logical fixes * Remove / Handle non-null assertions which are certainly unnecessary (e.g. in tests)
