Requirements ------------ [](#requirements) - Silverstripe CMS 6.x - [voku/html-min 4 || 5](https://packagist.org/packages/voku/html-min) Note: this version is compatible with SilverStripe 6. For SilverStripe 5, please see the [2 release line](https://github.com/xini/silverstripe-minify-html/tree/2). Installation ------------ [](#installation) Install the module using composer: ``` composer require innoweb/silverstripe-minify-html dev-master ``` Then run dev/build. Enabling minification --------------------- [](#enabling-minification) Once installed, HTML minification is enabled by default. See the example configuration in `config/envtoggle.yml.example` for how to toggle minification on/off for your environment via a `.env` variable. In the example, a `.env` variable named `HTML_MINIFICATION_ENABLED` can be added, which will enable/disable minification based on whether the value is true or false/absent. Configuration ------------- [](#configuration) The config variables are derived from voku's library and adjusted to work with Silverstripe. The following config values are available: ``` Innoweb\MinifyHTML\Util\HTMLMinifier: // Disable all optimisations, e.g. for dev environment enable_minification: true // optimize html via voku's "HtmlDomParser()" optimize_via_html_dom_parser: true // remove default HTML comments // (depends on optimize_via_html_dom_parser: true) // (disabled by default) remove_comments: false // sum-up extra whitespace from the Dom // (depends on optimize_via_html_dom_parser: true) sum_up_whitespace: true // remove whitespace around tags // (depends on optimize_via_html_dom_parser: true) remove_whitespace_around_tags: true // optimize html attributes // (depends on optimize_via_html_dom_parser: true) optimize_attributes: true // remove optional "http:"-prefix from attributes // (depends on optimize_via_html_dom_parser: true) // (disabled by default) remove_http_prefix_from_attributes: false // remove optional "https:"-prefix from attributes // (depends on optimize_via_html_dom_parser: true) // (disabled by default) remove_https_prefix_from_attributes: false // remove defaults // (depends on optimize_via_html_dom_parser: true) // (disabled by default) remove_default_attributes: false // remove deprecated anchor-jump // (depends on optimize_via_html_dom_parser: true) // (disabled by default) remove_deprecated_anchor_name: false // remove deprecated charset-attribute - the browser will use the charset from the HTTP-Header, anyway // (disabled by default) remove_deprecated_script_charset_attribute: false // remove deprecated script-mime-types remove_deprecated_type_from_script_tag: true // remove "type=text/css" for css links remove_deprecated_type_from_stylesheet_link: true // remove "media="all" from all links and styles // (disabled by default) remove_default_media_type_from_style_and_link_tag: false // remove type="submit" from button tags // (disabled by default) remove_default_type_from_button: false // remove some empty attributes // (depends on optimize_via_html_dom_parser: true) remove_empty_attributes: true // remove 'value=""' from empty // (depends on optimize_via_html_dom_parser: true) remove_value_from_empty_input: true // sort css-class-names, for better gzip results // (depends on optimize_via_html_dom_parser: true) sort_css_class_names: true // sort html-attributes, for better gzip results // (depends on optimize_via_html_dom_parser: true) sort_html_attributes: true // remove more (aggressive) spaces in the dom // (disabled by default) remove_spaces_between_tags: false // remove quotes e.g. class="lall" => class=lall // (disabled by default) remove_omitted_quotes: false // remove ommitted html tags e.g. lall => lall // (disabled by default) remove_omitted_html_tags: false ``` License ------- [](#license) BSD 3-Clause License, see [License](license.md) ### Health Score 51 — FairBetter than 95% of packages Maintenance88 Actively maintained with recent releases Popularity27 Limited adoption so far Community14 Small or concentrated contributor base Maturity61 Established project with proven stability Bus Factor1 Top contributor holds 78.6% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
