size-plugin

A webpack plugin that tracks and displays the gzipped sizes of your assets over time, showing deltas from the previous build. Current stable version is 3.0.0 (2021). Released as needed; maintained by Google Chrome Labs. Key differentiators: simple setup, built-in compression options (gzip, brotli, none), TypeScript types, and automatic file size persistence. Compare to webpack-bundle-analyzer which visualizes composition, or bundlesize which enforces thresholds.
