terser-webpack-plugin

Webpack plugin that uses Terser to minify/minimize JavaScript output. Current stable version 5.5.0, with frequent releases (multiple per year). Ships TypeScript definitions. Key differentiator: integrates deeply with webpack's optimization pipeline, supports source maps, parallelization via worker threads, and custom minimizers (e.g., swc, esbuild). Requires webpack ^5.1.0. Active maintenance by webpack team.
