rollup-plugin-eslint-bundle

Rollup plugin that runs ESLint validation on the final bundled output rather than individual source files, allowing you to check and auto-fix the generated bundle. Current stable version is 9.0.0, targeting Node >=20, Rollup 4.x, and ESLint >=8.x. The plugin works as a build-time step, useful for enforcing lint rules on the bundle itself (e.g., code style, prohibited patterns). Differentiators: operates on the bundle, not sources; supports ESLint's fix mode; includes both Rollup config and JavaScript API usage. This plugin is actively maintained.
