Essential TypeScript Utility Types

util-ts-types is a TypeScript utility library providing a curated collection of essential, reusable type constructs designed to simplify complex type manipulations within TypeScript projects. Currently at version 1.0.0, this package appears to be primarily maintained for internal consumption, evidenced by its 'private' designation in the README. As a type-only library, its release cadence is likely tied to internal project needs rather than public API changes, implying stability but infrequent external updates for the broader community. Key differentiators typically involve a set of opinionated or project-specific utility types that might not be available directly in TypeScript's built-in `lib.d.ts` or widely adopted libraries like `type-fest`, focusing on solving specific organizational typing challenges without introducing runtime dependencies.
