Bundle buddy helps you find duplicated code across your bundle splits.

As code splitting becomes more and more common, there is not enough visibility into what is actually ending up in our bundles. This makes it trivial to end up shipping the same exact code in different bundles.

To detect duplicated code across bundles, bundle buddy uses source maps from each of our chunks to extract the overlap. Run bundle buddy with a path to each of your source maps to run the analysis.
