I have slowly been developing a custom app that interfaces with several external APIs that supply additional data to airtable entries. I started out with the utility as an automation script - here I was able to use remoteFetchAsync() to avoid any CORS issues with my fetch calls. However, since moving to the custom app and React, I am having to go through the proxy at https://cors-anywhere.herokuapp.com/ to run my API calls (and avoid the CORS preflight errors).
The issue is the proxy is only for development - I would like to either duplicate what it does myself or find a similar service that does the same thing. I am relatively new to JS and web development, so I am looking for a well documented solution that would be easy to implement in a few hours. Does anyone have any hints on where to look?
Since Airtable has the server fetch functionality built in for scripts, is it also possible to use it in custom apps?
