Utility function to create a promise, and return the promise + reject + resolve

makeResolvablePromise.ts

type ResolvablePromise<Value = void> = {
    promise: Promise<Value>;
    resolve: (value: Value | PromiseLike<Value>) => void;
    reject: (reason?: any) => void;
};

export function makeResolvablePromise<Value = void>(): ResolvablePromise<Value> {
    let resolveFunction: (value: Value | PromiseLike<Value>) => void;
    let rejectFunction: (reason?: any) => void;

    // Create a promise and store its resolve and reject functions
    const promise = new Promise<Value>((resolve, reject) => {
        resolveFunction = resolve;
        rejectFunction = reject;
    });

    // Ensure resolve and reject functions are initialized
    if (!resolveFunction || !rejectFunction) {
        throw new Error("Failed to initialize resolve and reject functions");
    }

    return {
        promise,
        resolve: resolveFunction,
        reject: rejectFunction,
