rollup-plugin-peer-deps-external

Automatically externalizes peerDependencies in Rollup bundles. Current stable version is 2.2.4 (last released October 2020), with a maintenance status. It eliminates manual enumeration of peer dependencies in the `external` config, supports module paths (e.g., `lodash/map`), and includes an optional `includeDependencies` flag. Compared to manually listing externals or using pattern-based approaches, this plugin provides a zero-config solution that reads from package.json. It is widely used in library bundling workflows and has minimal dependencies (only `rollup` as a peer dependency). Release cadence is low; no new features since 2.2.0.
