A free WordPress plugin that makes popular open-source icon packs available as native WordPress icons: in the core Icon block, in a shortcode, and in your own PHP.

Requires WordPress 7.1 (for the Icons API) and PHP 7.4.

[infinite_icon name="lucide/heart" size="32" color="#c00"]
echo infinite_icons_get( 'lucide/star', array( 'size' => 32, 'label' => 'Featured' ) );

How it works

WordPress core sanitizes every registered icon with wp_kses() and keeps only <svg>, <path> and <polygon>; all stroke attributes are removed. Stroke-drawn outline sets (Lucide, Tabler outline, Heroicons outline) would therefore render as nothing.

Icons are converted ahead of time instead, by a separate pipeline in infinite-icons-packs: strokes are expanded to filled outlines, all shapes are boolean-united into one path, and each result is compared against a render of the original before it ships. What the plugin registers is already in the exact form the sanitizer preserves:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path fill="currentColor" d="…"/></svg>

Icons register with file_path, so core reads and sanitizes each SVG only when it is first rendered: 1,815 registered icons cost no file reads on a request that renders none.

Packs

Lucide is bundled with the plugin. Packs are directories, either in this plugin's packs/ directory or in uploads/infinite-icons/packs; a pack in uploads supersedes a bundled pack with the same slug.

Development

composer install
composer lint          # PHPCS: WordPress-Extra + WordPress-Docs
composer analyse       # PHPStan level 6
composer test          # PHPUnit

Running the tests

The suite needs the WordPress test library and a throwaway database:

# 1. A database the tests may DROP tables in.
mysql -e "CREATE DATABASE wordpress_test"

# 2. The test library, matching the WordPress version under test.
curl -sSL https://github.com/WordPress/wordpress-develop/archive/refs/tags/7.1.0.tar.gz \
  | tar -xz --strip-components=3 -C /tmp/wordpress-tests-lib \
      wordpress-develop-7.1.0/tests/phpunit/includes \
      wordpress-develop-7.1.0/tests/phpunit/data

# 3. Point the suite at both, plus a wp-tests-config.php.
export WP_TESTS_DIR=/tmp/wordpress-tests-lib
export WP_TESTS_CONFIG_FILE_PATH=/path/to/wp-tests-config.php
composer test

WP_TESTS_CONFIG_FILE_PATH must point at a wp-tests-config.php whose ABSPATH is a WordPress 7.1 install. Start from wp-tests-config-sample.php in the same tarball.
