Type Error: Argument of type 'string | undefined' in shoutConnected

[heydarideveloper]

Hi there,
I encountered a TypeScript error while using the shoutConnected(connection.id) function in the react-signalr package. The error message is as follows:

Argument of type 'string | undefined' is not assignable to parameter of type 'string | null'.
Type 'undefined' is not assignable to type 'string | null'.

Issue Description
The issue occurs because connection.id can potentially be undefined, but the shoutConnected function expects a parameter that is either a string or null.
Proposed Solution
To fix this issue, I modified the function call to ensure it only passes a valid string or null value. I implemented the following change:

shoutConnected(connection.id || null);

This adjustment ensures that if connection.id is undefined, it will pass null instead, which aligns with the expected parameter type.
Merge Request
I have created a merge request with this fix. You can find it here: #40 (comment)
Thank you for your attention to this matter! I hope this helps improve the package for everyone.
Best regards,
