While trying to use the express server, i was somehow not able to debug apps in Chrome by setting breakpoints. I tried changing the devtool option within the config file as well to source-map, but it didnt work.
After that, i tried using webpack-dev-server and then i was able to debug the application within Chrome. Anyone else facing this issue while using express server rather than webpack-dev-server? I was using the branch: react-router-redux.
