'React / Express Isssues with update values into a json file / db

I am trying to create a small application that maps over data and takes an input field which then can be updated to the json file. I am using Axios for get req and the put req but I need advice / help on connecting the json / db to my react app. Is this where I should use Express? Or Can Axios run the put / patch req?

Here is a code sandbox of my example

Any help is always appreciated :)

Cheers!!
