Move the HTML minifier implementations from `html-minimizer-webpack-plugin` into this plugin so HTML assets can be minified via the standard `TerserPlugin` interface. Adds four new static helpers: - `TerserPlugin.htmlMinifierTerser` (uses `html-minifier-terser`) - `TerserPlugin.swcMinifyHtml` (uses `@swc/html` for full documents) - `TerserPlugin.swcMinifyHtmlFragment` (uses `@swc/html` for fragments) - `TerserPlugin.minifyHtmlNode` (uses `@minify-html/node`) The HTML packages are declared as optional peer dependencies — install only the one you actually use. Documentation in the README now includes a dedicated HTML section with usage examples for each minimizer.
Replace the brief intro with a structured overview that groups every built-in minimizer (JS, JSON, HTML) under its asset type, names the static helper, links the upstream tool, and notes which optional peer dependency to install. This makes it easy to pick the right minimizer without reading the full Examples section.

Replace the standalone unit tests with end-to-end tests that go through the full webpack pipeline — same pattern used by `test/minify-option.test.js` for `terserMinify`, `swcMinify`, `esbuildMinify`, and `jsonMinify`. Each test now spins up a webpack compiler with `getCompiler`, applies a `TerserPlugin` configured for HTML, runs `compile`, and snapshots the emitted assets, errors and warnings via `readsAssets` / `getErrors` / `getWarnings`. New fixtures (`file.html`, `fragment.html`, plus matching `html.js`/`html-fragment.js` entries that reference them via `new URL(...)`) drive the asset emission, mirroring the existing `fixtures/json.js` / `fixtures/file.json` setup for `jsonMinify`. Coverage: each HTML minimizer (`htmlMinifierTerser`, `swcMinifyHtml`, `swcMinifyHtmlFragment`, `minifyHtmlNode`) is exercised with default options, plus dedicated cases for custom `minimizerOptions`, `parallel: true` / `false` (htmlMinifierTerser, which supports worker threads), and an array-of-`minify` chaining case.
Fold the 10 HTML-minimizer cases (and their snapshots) into the existing `minify option` describe block in `test/minify-option.test.js`, alongside the JS, JSON, and esbuild cases that already live there. The standalone `test/htmlMinimizers.test.js` and its dedicated snapshot file are removed. The HTML fixtures (`fixtures/file.html`, `fixtures/fragment.html`, `fixtures/html.js`, `fixtures/html-fragment.js`) stay where they are and are now consumed from `minify-option.test.js`.
- Quote `parallel` and `true`/`false` with double quotes (matching the existing 'should work when the "parallel" option is "true"' style at the top of the file). - Rename the array-of-`minify` chaining case to mirror the existing "should work when \`minify\` is an array of functions" wording. Snapshots are regenerated under the new keys; obsolete keys removed.
