bundle-cop 👮‍♀️

Generate a bundle size comparison between two different branches

You can see an example here

Usage

$ bundle-cop --branch master

Bundle cop compares the current branch with the one specified using the --branch command.

After comparing, it will generate an index.html file which is automatically has a breakdown of file size changes

Both branches will need to contain a npm run build-analyze script that ensures we're using our webpack-bundle-analyzer plugin.

You'll want to use this webpack plugin as well

npm i webpack-bundle-analyzer --save-dev

and your next.config.js will need something like this:

const { BundleAnalyzerPlugin } = require('webpack-bundle-analyzer')

..

if (process.env.ANALYZE) {
  config.plugins.push(new BundleAnalyzerPlugin({
    statsFilename: 'stats.json',
    analyzerMode: 'disabled',
    generateStatsFile: true
  ))
}
