Compare mode

In compare mode, the metrics are compared against an existing(node_modules/.cache/bundle-stats/baseline.json) rollup stats file(baseline). To generate the baseline webpack stats, set BUNDLE_STATS_BASELINE environmental variable to true or set the plugin baseline option to true:

# Checkout to the branch/tag/commit where you want to generate the baseline
$ git checkout master

# Build your application with BUNDLE_STATS_BASELINE environmental variable
$ BUNDLE_STATS_BASELINE=true npm run build

# Checkout to the working branch/tag/commit
$ git checkout MY_FEATURE_BRANCH

# Build your application
$ npm run build

The option can be disabled by setting the plugin compare option to false.
