tsafe

A collection of utility functions and type helpers for TypeScript, currently at version 1.8.12. Released frequently (multiple releases in 2024). Provides runtime functions like assert and assertDeepEqual, along with type-level utilities such as Equals, EqualsT, ReturnType of, UnpackPromise, Assert, Id, etc. No runtime dependencies. Tree-shakable and supports Deno. Differentiates by offering TypeScript utility types that require runtime implementations (e.g., assertion functions), complementing the standard library.
