Namespace ts-types

Package: @litert/utils-ts-types

This namespace provides static TypeScript utility types for use in generic constraints, type-level programming, and common type transformations. It contains no runtime code — all exports are compile-time-only type declarations.

Install

Use this package only:

npm i @litert/utils-ts-types

Or install the full bundle:

npm i @litert/utils

And then import from it.

import type * as LibUtils from '@litert/utils';
type MyObj = LibUtils.IObject;

// or
import type { IObject } from '@litert/utils';

Errors
