Type Alias ComposeMany<Fns>

ComposeMany: Fns extends [infer F, infer G, ...(infer Rest)]
    ? F extends (...args: any[]) => any
        ? G extends (...args: any[]) => any
            ? ComposeMany<
                [Compose<F, G>, ...Extract<Rest, ((...args: (...)[]) => any)[]>],
            >
            : never
        : never
    : Fns extends [infer F] ? F : never

Compose multiple functions in sequence.

Type Parameters

Fns extends ((...args: any[]) => any)[]
Array of function types to compose

Remarks

Chains several functions together, ensuring type compatibility. The output of each function must match the input of the next. Used Compose recursively.

Example

type F1 = ( x: number ) => string;
type F2 = ( y: string ) => boolean;
type F3 = ( z: boolean ) => Date;
type ComposedMany = ComposeMany< [ F1, F2, F3 ] >; // ( arg: number ) => Date
