Invokable

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

1. A function InvokableFn
2. An object with a specific invocation signature (IInvokableObject)

Types

• Invokable - Union type of InvokableFn and IInvokableObject
• InvokableFn - Function signature
• IInvokableObject - Object with invoke method

Function Invokable (InvokableFn)

Represents a standard function with typed parameters and return value.

import type { InvokableFn } from "@daiso-tech/core/utilities";

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

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

Object Invokable (IInvokableObject)

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 { IInvokableObject } from "@daiso-tech/core/utilities";

class InvokableObject
    implements IInvokableObject<[arg1: number, arg2: number], number>
{
    invoke(arg1: number, arg: number2): number {
        throw new Error("Method not implemented.");
    }
}

const invokableObject: IInvokableObject<[arg1: number, arg2: number], number> =
    {
        invoke(arg1: number, arg: number2): number {
            throw new Error("Method not implemented.");
        },
    };
