saqqdy/rollup-plugin-add-banner

rollup-plugin-add-banner is a Rollup (and Vite‑compatible) plugin that automatically prepends customizable banner comments to generated bundles. It lets developers inject information such as package name, version, author, or any custom variables—directly from package.json or a user‑defined source—supports different banners per file type, include/exclude glob patterns, environment‑based toggling, and works with source maps. The tool is aimed at front‑end library or application authors who want a simple way to add licensing or build‑metadata headers to their distributed JavaScript/CSS assets.
