Webpack Compare

Fork of https://github.com/Southpaw17/webpack-compare

Install

npm i -g webpack-compare

Introduction

Ever wonder if a change you made, either to your build configuration or source, had a positive impact on the size of your Webpack bundles? webpack-compare aims to provide an easy-to-read comparison between a previous build and your latest build. Just use the StatsWriterPlugin to collect some info about your build and pass the stats.json into webpack-compare to see how your bundle sizes have changed over time.

Usage

Run your Webpack build to produce a stats.json from the StatsWriterPlugin. Store that somewhere so it doesn't get overwritten by a future build. Make whatever changes you want to test and run the Webpack build again to generate an updated stats.json. Then, run the cli to produce a report.

webpack-compare stats-old.json stats.json

Then open up compare/index.html in your favorite browser. If you want to change the output path just do the following:

webpack-compare stats-old.json stats.json -o /sweet/new/path

And you'll find your report at /sweet/new/path/index.html.
