babel-plugin-add-filehash

A Babel plugin that forces output to change whenever the input file changes, even for trivial/whitespace changes. Version 7.6.0 is current, but the primary use case (forcing Webpack to show updated eslint messages on unchanged files) has been obsolete since Webpack v3.5.4 fixed the underlying issue. The plugin remains functional for anyone needing deterministic output changes, but it is effectively a legacy tool. It has no dependencies beyond Babel itself and is a zero-config plugin.
