Type Alias MergeMany<T>

MergeMany: Simplify<
T extends [infer H, ...(infer R)] ? Merge<H, MergeMany<R>> : {},
>

Merge multiple object types sequentially.

Type Parameters

T extends unknown[]
Tuple of object types

Remarks

Applies shallow merges from left to right over a tuple of object types.

Example

type A = { a: number };
type B = { b: string };
type C = { b: number };
type D = { c: boolean };
type Merged = MergeMany< [ A, B, C, D ] >;
// { a: number, b: number, c: boolean }
