Webpack Visualizer

How do I get stats JSON from webpack?

webpack --json > stats.json

If you're customizing your stats output or using webpack-stats-plugin, be sure to set chunkModules to true (see here for an example).

This tool is also available as a webpack plugin. See here for usage details.

npm install webpack-visualizer-plugin

Due to limitations in Webpack's stats, the "actual" (minified) numbers reported here are approximate, but they should be pretty close.

Disc for Browserify did this first. Thanks also to this example from the D3 gallery for demonstating how to create sunburst charts.
