Invocable

An Invocable represents a callable entity, which can be either:

1. A function InvocableFn
2. An object with a specific invocation signature (IInvocableObject)

Types

• Invocable - Union type of InvocableFn and IInvocableObject
• InvocableFn - Function signature
• IInvocableObject - Object with invoke method

Function Invocable (InvocableFn)

Represents a standard function with typed parameters and return value.

import type { InvocableFn } from "eridu-tech/utilities";

// Using InvocableFn
type AddFunction = InvocableFn<[arg1: number, arg2: number], number>;

// Equivalent to:
type TraditionalFunction = (arg1: number, arg2: number) => number;

Object Invocable (IInvocableObject)

An object that implements a callable contract through an invoke method. This pattern is especially useful for dependency injection (DI) integration, as most DI frameworks are adapted for class-based resolution.

import type { IInvocableObject } from "eridu-tech/utilities";

class InvocableObject implements IInvocableObject<
    [arg1: number, arg2: number],
    number
> {
    invoke(arg1: number, arg2: number): number {
        throw new Error("Method not implemented.");
    }
}

const invocableObject: IInvocableObject<[arg1: number, arg2: number], number> =
    {
        invoke(arg1: number, arg2: number): number {
            throw new Error("Method not implemented.");
        },
    };
