Strips redundant whitespace, comments, optional tags, and default attributes, then sorts what's left so your gzip layer has less work to do. Built on native `\DOMDocument` — no third-party DOM dependencies. Requirements ------------ [](#requirements) - PHP **8.3**, 8.4, or 8.5 - ext-dom, ext-libxml, ext-mbstring Installation ------------ [](#installation) ``` composer require akankov/html-min ``` Usage ----- [](#usage) ``` use Akankov\HtmlMin\HtmlMin; $html = doRemoveComments(true) // drop HTML comments (conditional comments are preserved) ->doSumUpWhitespace(true) // collapse runs of whitespace in text nodes ->doRemoveWhitespaceAroundTags(false)// aggressive: also trim whitespace adjacent to block tags ->doRemoveSpacesBetweenTags(false) // aggressive: remove whitespace-only text nodes between elements // Attribute optimization ->doOptimizeAttributes(true) ->doSortHtmlAttributes(true) // canonical attribute order → better gzip ->doSortCssClassNames(true) // canonical class order → better gzip ->doRemoveOmittedQuotes(true) // class="foo" → class=foo when safe ->doRemoveOmittedHtmlTags(true) // x → x where the closing tag is optional ->doRemoveOmittedHtmlStartTags(false)// aggressive: also omit the // START tags ->doRemoveEmptyAttributes(true) ->doRemoveValueFromEmptyInput(true) ->doRemoveDefaultAttributes(false) // opt-in: drop defaults like form method=get // URL attribute trimming ->doRemoveHttpPrefixFromAttributes(false) ->doRemoveHttpsPrefixFromAttributes(false) ->doKeepHttpAndHttpsPrefixOnExternalAttributes(false) ->doMakeSameDomainsLinksRelative([]) // e.g. ['example.com'] → strip host from same-site links // Deprecated attribute cleanup ->doRemoveDeprecatedAnchorName(true) ->doRemoveDeprecatedScriptCharsetAttribute(true) ->doRemoveDeprecatedTypeFromScriptTag(true) ->doRemoveDeprecatedTypeFromStylesheetLink(true) ->doRemoveDeprecatedTypeFromStyleAndLinkTag(true) ->doRemoveDefaultMediaTypeFromStyleAndLinkTag(true) ->doRemoveDefaultTypeFromButton(false) // Inline CSS / JS minification (opt-in, off by default) ->doMinifyInlineCss(false) // minify the contents of inline blocks ->doMinifyInlineJs(false); // minify the contents of inline blocks echo $htmlMin->minify($html); ``` Each setter returns `$this`, so you can configure and call `minify()` in one chain. ### Presets [](#presets) `MinifierOptions` ships three named starting points so you don't have to reason about all 27 flags at once: ``` use Akankov\HtmlMin\Config\MinifierOptions; use Akankov\HtmlMin\HtmlMin; $balanced = new HtmlMin(MinifierOptions::defaults()); // same as new HtmlMin() $smallest = new HtmlMin(MinifierOptions::aggressive()); $shapeStable = new HtmlMin(MinifierOptions::conservative()); ``` - **`defaults()`** — the balanced configuration shown above. Safe for almost any HTML; output is spec-equivalent to the input. - **`aggressive()`** — maximum byte savings within what the HTML5 spec allows. Adds block-tag whitespace trimming, whitespace-only text-node removal, ``/``/`` start-tag omission, spec-default attribute removal, and inline CSS/JS minification. Two trade-offs to know: whitespace between *inline* elements is rendering-significant, so markup that relies on ` ` spacing can render tighter; and start-tag omission can reduce an effectively-empty document — a bare html/head/body skeleton — to an empty string, which is correct per spec but surprising the first time. URL scheme stripping stays off even here because protocol-relative URLs change meaning outside an http(s) context. - **`conservative()`** — shape-preserving: only collapses whitespace runs, strips comments, and drops spec-redundant deprecated attributes. Keeps optional end tags, attribute quotes, attribute/class order, and empty attributes. Use it when output is diffed against input, post-processed by shape-sensitive tools, or styled via selectors like `[data-x=""]`. Presets are plain constructors — start from one and override per-flag with the fluent setters if you need a variation. Inline CSS and JS minification ------------------------------ [](#inline-css-and-js-minification) By default the contents of `` and `` blocks round-trip untouched. Enable the two opt-in toggles to minify them: ``` $htmlMin = (new HtmlMin()) ->doMinifyInlineCss(true) ->doMinifyInlineJs(true); echo $htmlMin->minify($html); ``` The bundled minifiers are zero-dependency and conservative: - **CSS** — strips `/* … */` comments and collapses whitespace; the contents of strings and `url(…)` are preserved. - **JS** — removes comments and collapses horizontal whitespace while preserving newlines (so Automatic Semicolon Insertion is unaffected), strings, regex literals, and template literals. Identifiers are never renamed. Scripts that are not JavaScript are left alone automatically: a ``whose `type` is, for example, `application/ld+json` or `text/x-template`, and any ``, passes through unminified. ### Using a different minifier [](#using-a-different-minifier) For aggressive minification (identifier renaming, dead-code removal), plug in a third-party tool with `setInlineCssMinifier()` / `setInlineJsMinifier()`. Each takes any `callable(string): string`; pass `null` to restore the bundled default. ``` use MatthiasMullie\Minify; // composer require matthiasmullie/minify $htmlMin = (new HtmlMin()) ->doMinifyInlineCss(true) ->doMinifyInlineJs(true) ->setInlineCssMinifier(static fn (string $css): string => (new Minify\CSS($css))->minify()) ->setInlineJsMinifier(static fn (string $js): string => (new Minify\JS($js))->minify()); echo $htmlMin->minify($html); ``` If a bundled minifier throws, the original source is kept and a warning is sent to the PSR-3 logger (when one is set via `setLogger()`), so a minifier bug can never corrupt the page. User-supplied callables let their exceptions propagate. Command line ------------ [](#command-line) The package ships a small CLI at `vendor/bin/html-min` — handy for one-off minification, build pipelines, and inspecting what a config change does: ``` vendor/bin/html-min page.html # minify a file to stdout vendor/bin/html-min page.html --output=page.min.html cat page.html | vendor/bin/html-min # stdin → stdout vendor/bin/html-min page.html --minify-inline-css --minify-inline-js ``` Exit codes: `0` success, `1` I/O failure (unreadable input / unwritable `--output`), `2` invalid argument. `--help` prints the full usage text. `make phar` builds a self-contained `dist/html-min.phar` for use outside a Composer project. Extending --------- [](#extending) To run your own pass over every element during minification, implement `Akankov\HtmlMin\Contract\DomObserver` and register it: ``` use Akankov\HtmlMin\Contract\DomObserver; use Akankov\HtmlMin\Contract\HtmlMinInterface; use Akankov\HtmlMin\HtmlMin; final class StripDataTestIds implements DomObserver { public function domElementBeforeMinification(\DOMElement $element, HtmlMinInterface $htmlMin): void { } public function domElementAfterMinification(\DOMElement $element, HtmlMinInterface $htmlMin): void { if ($element->hasAttribute('data-testid')) { $element->removeAttribute('data-testid'); } } } $htmlMin = new HtmlMin(); $htmlMin->attachObserverToTheDomLoop(new StripDataTestIds()); echo $htmlMin->minify($html); ``` Observer practicalities worth knowing before you ship one: - **Phases.** `attachObserverToTheDomLoop()` takes an optional `ObserverPhase` (`Before`, `After`, or the default `Both`): `domElementBeforeMinification()` runs in the pre-pass, before attribute optimization; `domElementAfterMinification()` in the post-pass. Register for only the phase you need — each hook fires for **every element** on every `minify()` call, so heavy work multiplies across the document. - **Ordering.** Observers run in registration order within a phase, and the built-in `OptimizeAttributes` observer is registered first (in the `After` phase) — your after-phase observers see already-optimized attributes. There is no priority system. - **Branch on the live config.** The second argument is the owning `HtmlMinInterface`; its `isDo*()` getters reflect the actual flags, so an observer can follow e.g. `isDoRemoveHttpPrefixFromAttributes()` instead of duplicating configuration. - **Exceptions propagate.** The DOM walk does not wrap observer calls — a throwing observer aborts the whole `minify()` call. Catch inside the observer if a page must never break on observer bugs. - **Mutating the tree is the point**, but removing the element you were just handed (or re-parenting its ancestors) mid-walk can skip nodes — prefer attribute and text mutations, and removal of *descendants*.
