Error

Expected

Application loads with no issue.

Actual

When executing the application on Android API 28 it throws an error: Strict mode does not allow function declaration in a lexically nested statement.... If any reference to react-native-rss-parser is removed from the application, it runs flawlessly.

Thanks for the detailed bug report (and sorry for the delay). I will need to try and reproduce this bug and then i can see if i can come up with a solution by fixing my function declarations. It seems like changes were done to babel to force this strict mode.

I will post here once i find a solution

I am not able to reproduce this bug. If you are still using react-native-rss-parser can you try upgrading to the newest version (v1.4.0) and see if it still has the problem. I did some code cleanup in this release.
