@typescript-eslint/type-utils

Type utilities for working with TypeScript within ESLint rules.

The utilities in this package are separated from @typescript-eslint/utils so that that package does not require a dependency on typescript.

See https://typescript-eslint.io for general documentation on typescript-eslint, the tooling that allows you to run ESLint and Prettier on TypeScript code.
