rollup-plugin-combine

library2.1.1jsnpmunverified

A Rollup plugin that merges multiple JavaScript files into a single output, supporting both library and application builds. The current stable version is 2.1.1, released with a moderate cadence. It differentiates from similar plugins by offering fine-grained control over file ordering and custom transforms during concatenation. However, it lacks TypeScript support and is primarily used in legacy workflows where bundle splitting is not required.
