rollup-plugin-copy-merge

A Rollup plugin that copies files and folders with glob support and adds file merging capability on top of rollup-plugin-copy. Current version 1.0.3, stable, maintained. Key differentiator: allows merging multiple source files into a single destination file via the 'file' target property, unlike its predecessor. Requires Node >=14, ships TypeScript types, and relies on fs-extra, globby, and colorette as peer dependencies.
