Informations about the package wp-assets
NYCO WordPress Assets
A developer plugin with helpers for managing assets in WordPress. It can be used to register and enqueue stylesheets with general defaults and hashed names as well as configure inline integrations such as Google Analytics, Rollbar, etc by using WordPress' native wp_enqueue/register_style/script()
and wp_add_inline_script()
methods. This properly loads them into the site, avoids conflicts, and exposes them to asset hooks for deeper configuration.

Installation using Composer
$1 This package uses Composer Installers to install the package in the Must Use plugins directory (/wp-content/mu-plugins):
Not using Composer? Download an archive of the code and drop it into the mu-plugins directory.
$2 Create a proxy PHP loader file inside the mu-plugins directory, or use the one included with the plugin:
Usage
Quickstart. Declare namespace in functions.php (or any php file) and instantiate.
Migrating a block such as this...
... can be done with...
Assuming main.831f1593.js
is a compiled script file and 831f1593
is a hash based on the contents of the script, the filename will change if the contents of the file change. This is useful for cache busting without forcing a browser to load the script on every load using a query variable ?ver=831f1593
. However, WordPress won't be able to locate scripts without a hard-coded source. ->addScript('main')
will register and enqueue the first script file it finds with any hash contents between main.
and .js
.
Note. The autoloader sample sets an instance of WpAssets
to the global scope which can be used as well;
Documentation
The core of the plugin is a single class with several methods that are available upon instantiation. For a full description of methods refer to the source.
Class (including namespace)
Methods
- Add Script
- Add Style
- Add Attribute
- Load Integrations
- Add Inline
- Register Rest Routes
Add Script
Register and/or enqueue a hashed script based on it's name. File name should match the pattern script.{{ hash }}.js
by default. The separator between the filename and the hash can be configured.
...args
String $handle
The name of the file without a hashname. Default:'scripts'
Boolean $enqueue
Wether to enqueue the file or not. Default:true
Array $deps
Maps towp_register
|enqueue_script
$deps
argument. Default:array()
String $ver
Maps towp_register
|enqueue_script
$ver
argument. Default:null
Boolean $in_footer
Maps towp_register
|enqueue_script
$in_footer
argument. Default:true
String $sep
The separator between the base name and the hash. Default:'.'
Returns Key/value pair including wp_register_script response, wp_enqueue_script response, and the source uri of the file.
Examples
This will scan the default scripts assets directory assets/scripts/ of the current theme using the default pattern script.{{ hash }}.js, register the script with the handle script
and enqueue it. To pick a different script named main.{{ hash }}.js do the following;
This script will be loaded into the footer of the document and be available to the script_loader_tag filter;

Add Style
Register and/or enqueue a hashed style based on it's name. File name should match the pattern styles.{{ hash }}.css
. The separator between the filename and the hash can be configured.
...args
String $handle
The name of the file without a hashname. Default:'styles'
Boolean $enqueue
Wether to enqueue the file or not. Default:true
Array $deps
Maps towp_register
|enqueue_style
$deps
args. Default:array()
String $ver
Maps towp_register
|enqueue_style
$ver
args. Default:null
String $media
Maps towp_register
|enqueue_style
$media
args. Default:'all'
String $sep
The separator between the base name and the hash. Default:'.'
Returns Key/value pair including wp_register_style response, wp_enqueue_style response, and the source uri of the file.
Examples
This will scan the default style assets directory assets/styles/ of the current theme using the default pattern style.{{ hash }}.css, register the style with the handle style
and enqueue it. To pick a different style named site.{{ hash }}.css do the following;
Back to top
Add Attr
Uses the script_loader_tag
filter to add an attribute and a value to a specific script. For example; crossorigin="anonymous".
Attribute values may be strings. To add a boolean attribute such as async
or defer
pass true
."
...args
String $name
The name of the script.String $attr
The name of the attribute.String|Boolean $value
The value set for the attribute.

Load Integrations
This retrieves an integration configuration file from the MU Plugins directory. By default it will look for a YAML file at config/integrations.yml that contains an array of individual configuration objects then it converts the YAML file to a PHP Array and returns it. This is meant to be used with the ->enqueueInline( ...args )
method.
...args
String $path
Accepts a custom to the integrations file within the Must Use Plugins directory. Default'config/integrations.yml'
Returns an array of individual configuration objects.
A configuration file may include multiple objects with the following parameters.
Back to top
Add Inline
Register and enqueue inline scripts and their source using wp_register/enqueue_script()
and wp_add_inline_script()
Useful for cloud service integrations that are configured on the client-side (Google Analytics, Webtrends, Rollbar.js, etc.) what require loading a remote source but are configured with an inline script code block.
Also enqueues inline styles if required by the configuration. This is not possible by default and uses a technique described in this article.
...args
Array $script
Accepts a single key/value array of a configuration. Refer to the->loadIntegrations( ...args )
method.
Returns the same array with additional inline script contents.
Examples
This will load the 'google-analytics'
integration. Below is the Google Analytics configuration in config/integrations.yml...
The config/integrations/scripts/google-analytics.js script should contain something like the following;
The constant GOOGLE_ANALYTICS
should be defined somewhere in another part of your configuration (wp-config.php, functions.php, or this plugin works nicely with the nyco-wp-config plugin);
The following will be printed in the head of the document;
Back to top
Register Rest Routes
Uses an array of configuration objects to register WP Rest Routes that act as JavaScript files instead of inline scripts.
...args
Array $scripts
Array of integration objects (use ->loadIntegrations() to retrieve them).Function $auth
The authentication function to use for routes (passed to register_rest_route() as the'permission_callback'
argument).
Returns the Array of integrations objects with all rest route details.
Back to top
Enqueue Inline Helper Function
Use the included enqueue_inline( ...handle... )
helper function to quickly add integrations. It wraps around the example described above to make it easier to call integrations based on their handle in the config/integrations.yml file. The sample autoloader includes the helper function automatically.
Integration ACF Options Page Add-on
This plugin ships with an Integrations Options page add-on to allow WordPress admins to toggle integrations on or off. It requires Advanced Custom Fields to display the options page. Create a copy of the add-on in your mu-plugins directory.
The page will then appear under the Integrations menu item.
Query Monitor Add-on
This plugin ships with an add-on for Query Monitor that displays the available integrations to the Load Integrations method and compares them to integrations that are registered. It uses the same method to display the details of the config/integrations.yml file. The sample autoloader includes the add-on automatically.
