Ah - just read https://hackernoon.com/whats-new-with-server-side-rendering-in-react-16-9b0d78585d67#d14d which I didn't know about...

Yeah, let's avoid any possible performance issues as it is very possible the process.env would be hit per request in an SSR environment. Fixing the property name definitely helps though!! 😊

We could consider more docs around this to educate adopters and allow them to choose a performance strategy that suits them. 👍

[ctrlplusb]

Woops. I'll fix. Ta
