ts-essentials
A comprehensive collection of high-quality utility types for TypeScript to enhance type safety and developer experience.
What is ts-essentials?
ts-essentials is a TypeScript library that bundles a wide array of essential utility types and helper functions into a single package. It solves the problem of having to manually define or search for common but missing type utilities, providing stricter and more comprehensive alternatives to TypeScript's built-in types. The library enhances type safety and developer productivity by offering ready-to-use solutions for complex type transformations and validations.
TypeScript developers working on medium to large-scale applications who need advanced type utilities, stricter type safety, and tools for handling complex type scenarios like deep object transformations, nominal typing, and exhaustive checks.
Developers choose ts-essentials because it offers a well-tested, community-driven collection of utility types that are stricter and more predictable than many ad-hoc solutions. It fills gaps in TypeScript's standard library, provides runtime validation helpers, and ensures compatibility with modern TypeScript versions (4.5+), making it a reliable dependency for type-heavy projects.
