I'm using AWS Amplify to handle my ReactJS app. While it is convenient that AWS Amplify handles all backend functionality, I don't see any way I can write any of my own backend code to hide from the users. In particular, I'd like to hide my 3rd party API Key, and all the logic associated with the API results. Is there a way I can do this with Amplify or should I just try a different Amazon Compute service?
