Better Font Awesome Library

The easiest way to integrate Font Awesome into your WordPress project.

Introduction

The Better Font Awesome Library allows you to automatically integrate the latest available version of Font Awesome into your WordPress project, along with accompanying CSS, shortcode, and TinyMCE icon shortcode generator. Furthermore, it generates all the data you need to create new functionality of your own.

Features

Automatically fetches the most recent available version of Font Awesome, meaning you no longer need to manually update the version included in your theme/plugin.
Generates an easy-to-use PHP object that contains all relevant info for the version of Font Awesome you're using, including: version, stylesheet URL, array of available icons, and prefix used (icon or fa).
CDN speeds - Font Awesome CSS is pulled from the super-fast and reliable jsDelivr CDN.
Includes a TinyMCE drop-down shortcode generator.
Includes a local copy of Font Awesome to use as a fallback in case the remote fetch fails (or you can specify your own with the bfa_fallback_directory_path filter).
Utilizes transients to optimize for speed and performance.

Installation

The Better Font Awesome Library should ideally be installed via Composer:

composer require mickey-kay/better-font-awesome-library

Alternately, you can install the library manually, which can be useful for development and/or custom builds:

git clone https://github.com/MickeyKay/better-font-awesome-library.git
cd better-font-awesome-library
npm run build

Usage

Copy the /better-font-awesome-library folder into your project.
Add the following code to your main plugin file or your theme's functions.php file.

add_action( 'init', 'my_prefix_load_bfa' );
    /**
    * Initialize the Better Font Awesome Library.
    *
    * (see usage notes below on proper hook priority)
    */
    function my_prefix_load_bfa() {

    // Include the main library file. Make sure to modify the path to match your directory structure.
    require_once ( dirname( __FILE__ ) . '/better-font-awesome-library/better-font-awesome-library.php' );

    // Set the library initialization args (defaults shown).
    $args = array(
      'include_v4_shim'     => false,
      'remove_existing_fa'  => false,
      'load_styles'         => true,
      'load_admin_styles'   => true,
      'load_shortcode'      => true,
      'load_tinymce_plugin' => true,
    );

    // Initialize the Better Font Awesome Library.
    Better_Font_Awesome_Library::get_instance( $args );
}

If desired, use the Better Font Awesome Library object to manually include Font Awesome CSS, output lists of available icons, create your own shortcodes, and much more.

Usage Notes

The Better Font Awesome Library is designed to work in conjunction with the Better Font Awesome WordPress plugin. The plugin initializes this library (with its own initialization args) on the init hook, priority 5. When using the Better Font Awesome Library in your project, you have two options:

Initialize later, to ensure that any Better Font Awesome plugin settings override yours (this is the default behavior, shown above by initializing the library on the init hook with default priority 10.
Initialize earlier, to "take over" and prevent Better Font Awesome settings from having an effect.

Initialization Parameters ($args)

The following arguments can be used to initialize the library using Better_Font_Awesome_Library::get_instance( $args ):

$args['include_v4_shim']

(boolean) Include the Font Awesome v4 shim CSS stylesheet to support legacy icon.

true
false (default)

$args['remove_existing_fa']

(boolean) Attempts to remove existing Font Awesome styles and shortcodes. This can be useful to prevent conflicts with other themes/plugins, but is no guarantee.

true
false (default)

$args['load_styles']

(boolean) Automatically loads Font Awesome CSS on the front-end of your site using wp_enqueue_scripts().

true (default)
false - use this if you don't want to load the Font Awesome CSS on the front-end, or wish to do it yourself.

$args['load_admin_styles']

(boolean) Automatically loads Font Awesome CSS on the admin of your site using admin_enqueue_scripts().

true (default)
false - use this if you don't want to load the Font Awesome CSS in the admin, or wish to do it yourself.

$args['load_shortcode']

(boolean) Loads the included [icon] shortcode.

true (default)
false

load_tinymce_plugin

(boolean) Loads a TinyMCE drop-down list of available icons (based on the active Font Awesome version), which generates an [icon] shortcode.

true (default)
false

Deprecated

$args['version'] (2.0.0)

The library now always defaults to the latest available version of Font Awesome.

(string) Which version of Font Awesome you want to use.

'latest' (default) - always use the latest available version.
'3.2.1' - any existing Font Awesome version number.

$args['minified'] (2.0.0)

The library now always defaults to minified CSS.

(boolean) Use minified Font Awesome CSS.

true (default) - uses minifed CSS.
false - uses unminified CSS.

Shortcode

If either the $args['load_shortcode'] or $args['load_tinymce_plugin'] initialization arg is set to true, then the Better Font Awesome Library will include an [icon] shortcode that can be used as follows:

[icon name="star" class="2x spin" unprefixed_class="my-custom-class"]

name

The unprefixed icon name (e.g. star). The version-specific prefix will be automatically prepended.

class

Unprefixed Font Awesome icon classes. The version-specific prefix will be automatically prepended to each class.

unprefixed_class

Any additional classes that you wish to remain unprefixed (e.g. my-custom-class).

style

The specific icon style (e.g. brand vs. solid) to use.

Shortcode Output

The following shortcode:

[icon name="moon" style="solid" class="2x spin" unprefixed_class="my-custom-class"]

. . . will produce the following HTML:

<i class="fas fa-moon fa-2x fa-spin my-custom-class "></i>

get_stylesheet_url()

(string) Returns the Font Awesome stylesheet URL.

get_stylesheet_url_v4_shim()

(string) Returns the Font Awesome v4 shim stylesheet URL.

get_icons()

get_release_assets()

Deprecated

get_api_data() (2.0.0)

The library no longe relies on the jsDelivr CDN.

(object) Returns version data for the remote jsDelivr CDN (uses jsDelivr API). Includes all available versions and latest version.

Example:

// Initialize the library with custom args.
Better_Font_Awesome_Library::get_instance( $args );

$my_bfa = Better_Font_Awesome_Library::get_instance();

// Get info on the Better Font Awesome Library object.
$version = $my_bfa->get_version();
$stylesheet_url = $my_bfa->get_stylesheet_url();
$prefix = $my_bfa->get_prefix();
$icons = $my_bfa->get_icons();

// Output all available icons.
foreach ( $icons as $icon ) {
    echo $icon . '<br />';
}

Filters

The Better Font Awesome Library applies the following filters:

bfa_init_args

Parameters

$wp_remote_get_args (array)

bfa_fallback_release_data_path

Applied to the path for the fallback release data JSON file. Can be used to specify an alternate fallback data file.

Parameters

$fallback_release_data_path (string)

bfa_release_data_transient_expiration

This value controls how often the plugin will check for the latest updated version of Font Awesome. Can be used to increase/decrease the frequency of this check as desired.

Parameters

$api_expiration (int) (default: WEEK_IN_SECONDS)

bfa_icon_list

Applied to the icon array after it has been generated from the Font Awesome stylesheet, and before it is assigned to the Better Font Awesome Library object's $icons property.

Parameters

$icons (array)

bfa_icon_class

Applied to the classes that are output on each icon's <i> element.

Parameters

$class (string)

bfa_icon_tag

Applied to the tag that is output for each icon. Defaults is 'i', which outputs <i>.

The path must be to a local, non-remote, directory.

Parameters

$path (string)

bfa_api_transient_expiration (2.0.0)

Parameters

$css_expiration (int)

bfa_force_fallback (2.0.0)

There should no longer be a need to force a fallback.

Parameters

$force_fallback (false)

bfa_prefix (2.0.0)

Given the update to v5+ always, there should be no need to modify the icon prefix.

$prefix (string)

To Do

Ideas? File an issue or add a pull request!

Add README section on manually updating the fallback version.
Remove existing FA? - move to later hook so that it works for styles enqueued via shortcode (= wp_footer basically)
