It ships with several built-in minimizers covering JavaScript, JSON, HTML, and CSS — pick one with the [`minify`](#minify) option and target the right files with [`test`](#test). JavaScript minimizers: - [`terser`](https://github.com/terser/terser) — `MinimizerPlugin.terserMinify` (default). The same JavaScript-based minifier that webpack uses out of the box; produces small, well-tested output and supports the full set of `extractComments` modes. - [`uglify-js`](https://github.com/mishoo/UglifyJS) — `MinimizerPlugin.uglifyJsMinify`. ES5-only minifier, useful when you specifically need UglifyJS-compatible output. Requires `npm install --save-dev uglify-js`. - [`@swc/core`](https://github.com/swc-project/swc) — `MinimizerPlugin.swcMinify`. A very fast Rust-based JavaScript/TypeScript minifier. Requires `npm install --save-dev @swc/core`. - [`esbuild`](https://github.com/evanw/esbuild) — `MinimizerPlugin.esbuildMinify`. An extremely fast JS bundler/minifier; legal comments are always preserved (no `extractComments` support). Requires `npm install --save-dev esbuild`. JSON minimizer: - `JSON.stringify` — `MinimizerPlugin.jsonMinify`. Built in (no extra dependency); supports `space` and `replacer` options. HTML minimizers: - [`html-minifier-terser`](https://github.com/terser/html-minifier-terser) — `MinimizerPlugin.htmlMinifierTerser`. The default HTML minimizer. JavaScript-based, no native dependency. Requires `npm install --save-dev html-minifier-terser`. - [`@swc/html`](https://github.com/swc-project/swc) — `MinimizerPlugin.swcMinifyHtml` (full HTML documents) and `MinimizerPlugin.swcMinifyHtmlFragment` (HTML fragments, e.g. `
