What is the ideal way to utilize a Promise in order to retrieve this forthcoming value?

Here is a simplified version of my current code:

const getAuthorizedConnection = () => {
    let myAuthorizedConnection;
    flowable.subscribe({
        onComplete: connection => {
            connection
                .authorize(
                    authorizedConnection => {
                        myAuthorizedConection = authorizedConnection;
                    }
                )
                .subscribe(
                    messageFromConnection => {
                        processMessage(messageFromConnection);
                    }
                );
        }
    });
    return myAuthorizedConnection;
}

While the above code is incorrect, I believe using a Promise could help in returning the authorizedConnection when it's ready and saving it to a variable for reusability. However, I am struggling to implement this change. Can anyone provide guidance on how to correct this?

Answer №1

Could you provide further details regarding the concept of flawable? Assuming that flawable.subscribe serves as an observer and RxJS is a feasible choice, I might explore utilizing switchMap to convert the flowable observable (along with the connected response) into the result from .authorize
