    rollup-config-analyzer

    See what's bloating your bundle, how treeshaking has treated you, and other great stuff. Perfect for console printing an analysis of your bundle or integrating in your CI workflows.

    Comes in two scrumptious flavors:

    rollup-plugin-analyzer

    Adding as a plugin to your rollup config or build script will allow you to print a well formatted analysis to the console upon bundling or get a full analysis object for CI purposes.
