Ouch! This will make for a huge bundle. See https://webpack.github.io/docs/configuration.html#devtool

Surely the sourcemap is externalized to a separate file and only loaded if you attach a debugger, if the sourcemap is even deployed to prod together with the bundle at all (unlikely in my experience). 'source-map' produces much nicer traces than 'cheap-module-source-map', and both type of maps are going to be huge in any case.
