Attribute based event subscriptions

[bryanapellanes-okta]

User story

"As an okta-oidc-xamarin third party developer, I want to mark class methods with event related custom attributes so that they are automatically subscribed to Okta authentication related events."

Proposed solution

• Define custom attributes that relate one for one to each event defined in OktaContext.
• During Okta platform initialization scan asynchronously for methods adorned with event based custom attributes, accepting a filter to limit the total number of assemblies/classes/methods scanned, and automatically subscribe those methods to the relevant events.

Alternatives considered

Manually write code that subscribes to events of interest.

Additional information

Looking for feedback and comments to determine how valuable this would be.

Can you provide an example in pseudo-code?

Can you provide an example in pseudo-code?

The idea is to allow someone to write a class similar to the following and have methods automatically subscribed to relevant events without additional code needed:

public class MyOktaEventHandlers
{
    [OnSignInCompleted]
    public void LogSignIn(object sender, SignInEventArgs signInEventArgs)
    {
        ClaimsPrincipal claimsPrincipal = signInEventArg.StateManager.GetClaimsPrincipalAsync().Result;
        // ... do something with claims principal
        Console.WriteLine("Sign in completed");
    }
}
