babel-plugin-prismjs

A Babel plugin that transforms ES6 imports of PrismJS to include only specified languages, plugins, and themes, enabling tree-shaking and reduced bundle sizes for syntax highlighting. Version 2.1.0 is current, with stable release cadence. Requires Babel and PrismJS v1.18+. Key differentiator: automatically configures Prism for bundlers like Webpack without manual setup. Caveats: only works with ES6 import syntax, not CommonJS (require).
