Provide options to receive webpack --json

Versions

angular-cli: 1.0.0-beta.20-4
node: 6.9.1

Request

It would be very helpful if angular-cli did provide an option to receive output of webpack --json during ng build for further analysis of webpack chunks and code size (e.g. using the excellent webpack-visualizer: https://chrisbateman.github.io/webpack-visualizer/ or https://webpack.github.io/analyse/)

@JohannesRudolph I think this is a great idea for being able to produce dumps of information, in an attempt to see if it was possible, i ended up modifying 1 file and installing 1 package.

For those willing to play around with their node_modules for some fun, replace node_modules/angular-cli/models/webpack-config.js with this raw gist or you can view the gist

and then run npm install --save-dev webpack-stats-plugin and then whenever you do a build the stats are dumped in the outDir (typically dist/stats.json).

I agree that this would be helpful, but am unsure if we want to do it anytime soon because it would break the build system abstraction.

@filipesilva I agree this would be nice to have, the build system functioning is definitely more important than some stats, i would opt for a having people make the simple change i made if the stats are important to them (maybe for integration purposes). I've definitely grown accustomed to using the CLI and openly hacking away at anything that i'm curious on.
