AnonymousID typescript and safe access error

[connorpmullins]

Hi there, I'm working in a react native project using version 1.13.1 of the "@rudderstack/rudder-sdk-react-native" SDK.

ISSUE: In the below code you can see a red typescript warning

The error is that Type 'unknown' is not assignable to type 'string'.

PROPOSED SOLUTION:

• Could we type traits more strictly than Record<string, unknown>? I'm not sure what other values exist in traits, but manually typing unknown as string on my end is both a pain and unsafe.

EXTRA REQUEST:

• Could you remove nullability from anonymousID? It might not be possible, but I'm transitioning over from Segment and this is my only pain point so far. We rely on anonymousIDs for unauthenticated users in a number of places and having to handle it possibly being null is actually a little problematic.

Hey @connorpmullins,

I understand that you want a better way to fetch the anonymousId.

However, any value you set by calling our identify API is stored in traits. Since users can pass various types (String, Integer, Objects, etc.), we have defined the traits type as Record<string, unknown>. Therefore, it's not possible for us to change that.

As a temporary workaround, you can convert that value to a String.

A better solution would be for us to introduce a getAnonymousId API, which will return the anonymousId as a string. This API can be called after the SDK is initialized. I can forward this request to our team, and we will ensure to implement it in the future.

Please let me know if you have any further questions!

Thanks @1abhishekpandey !

Super helpful - mind updating here if/when getAnonymousId gets implemented?

Thank you!
