Beautify & Minify

Make your HTML source code pretty and/or compact.

The Beautify module buffers the HTML output of Drupal and processes it through a formatter - aka beautifier plugin.

Available beautifiers:
- Default (HTML): custom set of built-in search/replace functions
- htmLawed: custom battle-tested script (still WIP in #3301617: Implement htmLawed beautifier)
- Tidy: requires Tidy PHP extension installed on your environment

Beautifiers are plugins thus are configurable and extensible. You can create your own beautifier in your custom module too if you want. The default plugin provides functions for beautifying (auto-indentation), flattening (removing indentations) and compacting the HTML source output to the browser.

Page caching is an work in progress in #484756: Cache strategy . This module aims to leverage Drupal's cache so there should be no significant performance penalty, unless of course the chosen processing method increases the HTML file size (e.g. when using beautification over flattening or compacting). In general the flattening mode would provide a nice middle ground between performance improvement and code beautification. Not all options are available from all methods.

How to install

• Download the module
  composer require drupal/beautify
• Enable the module
  drush en beautify
• Go to admin page Admin > Config > Development > Beautifiers
