rollup-plugin-output-size

A Rollup plugin that displays output bundle sizes (uncompressed and gzipped) for assets, chunks, and entries. Current stable version is 2.0.0, released 2025, with peer dependency on Rollup ^2.0.0 || ^3.0.0 || ^4.0.0. Ships TypeScript types. Key differentiators: lightweight (zero dependencies since v2.0.0), uses Node.js built-in gzip and util.styleText, provides customization options (bytes, hide, gzip, silent, summary, handle), and exports utility functions (format, summarize). Actively maintained, with breaking changes in v2.0.0 requiring Node >=20.12.0 and removal of deprecated RollupOutputSizeOptions interface.
