Question about minification #21

I found that "npm run build" produces very small js file comparing to just using uglify. Just wondering what you did to achieve such high level of compression? I tried to look at make-webpack-config.js, but couldn't find anything special there. Thanks.

react has a lot for debug code which is garded with if(process.env.NODE_ENV !== "production"). The DefnePlugin + uglify removes this code in the production build.

Thanks a lot, I thought if(process.env.NODE_ENV !== "production") was for nodejs server. It all makes sense now.
