Vite/Rollup plugin to detect unused files and unused exports in used files
Vite/Rollup plugin to detect unused files and unused exports in used files.
This package is a ported version of webpack-deadcode-plugin.
Important
This plugin cannot check for dependencies of non-JavaScript files or exports (for example: CSS, or types from TypeScript files), which may be misreported as unused, even if they actually appear in the compiled bundles. Please be careful!
Warning
Rolldown does not report removed exports during tree shaking currently. Therefore, unused exports will never be reported in Vite 8 or higher.
