@tsed/schema

Usage

import { UnionToIntersection } from "@tsed/specs/schema/src/domain/types";

See /packages/specs/schema/src/domain/types.ts.

Overview

type UnionToIntersection<U> = (U extends any ? (k: U) => void : never) extends (k: infer I) => void ? I : never;

Description

Converts a union type to an intersection type.

This advanced TypeScript utility transforms a union of types (A | B | C) into an intersection of types (A & B & C), which is useful for schema composition and merging operations.

Usage

type Union = { a: string } | { b: number };
type Intersection = UnionToIntersection<Union>;
// Result: { a: string } & { b: number }
