Hello meteor community. I’m sorry if the answer to my question is super obvious, but i already spent a significant amount of time trying to solve this: Let’s assume a newly created, blank meteor app with only the 2 react packages (react and react-dom) added. meteor npm install --save react react-…

I’m getting this too, I think its just appeared. There is another thread on this, worth keeping an eye on it… [image] New react-devtools: Check if your production build is really in production mode react With react-devtools 2.15 , you can check if your build h…

Use production build of react in meteor app
