I’m working on a React Native App and AppSync, this will greatly help.

Thank you!

Wow, I have been looking for this for a long time! Thank you, I appreciate it.
I would like to know more about how to do calculations in GraphQL before showing the results to users.
For example: What is the average age for the employees? or How many employees are in this project (without getting all the employees. Let say there are 130 employees for this project but I don't want to get all of them to know how many employees assigned to it).

I get this error!
Do I need to setup something initially, I didn't have an cognito account or user pool configured already, if yes can be done later and if yes which files are then supposed to be modified ?
