rollup-plugin-filesize-check

A tiny Rollup plugin that validates that the output bundle size is within an expected range. Currently at version 1.2.0, it offers a simple API: provide an expected size (in kB) and a tolerance (warn) in kB. The plugin warns or errors if the actual size deviates beyond the tolerance. Unlike more feature-rich alternatives like rollup-plugin-filesize or rollup-plugin-sizes, this package focuses purely on size checking with minimal configuration and no visual reporting. It has stable, low release cadence, and is intended for developers who want CI-style size enforcement in their Rollup builds.
