Loading global environment variables in a single page app (SPA) in react/redux

I was trying to pass config variables from a backend written in Go to a single page app (SPA) written in react. For example, I wanted to set an "Env" flag to dev or prod or control whether you have to log in or not. Here's an example of the /api/config route that supplies this data:

{
    "Auth0ClientDomain": "odewahn.auth0.com", 
    "Auth0ClientID": "gcSxq9GfpUdVWNIvYiOsP7rh1s8u6ftA", 
    "ClientBrowser": "HTTPie", 
    "ClientOS": "darwin", 
    "Env": "dev", 
 "FirstClientLoad": "true",
