Creating modules

To create your very own Modularity module you simply create a plugin with a class that extends our Modularity\Module class.

A module actually is the same as a custom post type. However we've added a few details to enable you to use them as modules.

Use the $this->register() method to create a very basic module.

Here's a very basic example module for you:

/*
 * Plugin Name: Modularity Article Module
 * Plugin URI: -
 * Description: Article module for Modularity
 * Version: 1.0
 * Author: Modularity
 */

namespace MyArticleModule;

class Article extends \Modularity\Module
{
    public function __construct()
    {
        $id = 'article';
        $nameSingular = 'Article';
        $namePlural = 'Articles';
        $description = 'Outputs a full article with title and content';
        $supports = array('editor'); // All modules automatically supports title
        $icon = '[BASE-64 encoded svg data-uri]';
        $plugin = '/path/to/include-file.php' // CAn also be an array of paths to include 
        $cacheTTL = 60*60*24 //Time to live for fragment cache (stored in persistent object store redis / memcached). 

        $this->register(
            $id,
            $nameSingular,
            $namePlural,
            $description,
            $supports,
            $icon,
            $plugin,
            $cacheTTL
        );
    }
}

new \MyArticleModule\Article;

Module templates

You can easily create your own module templates by placing them in: /wp-content/themes/[my-theme]/templates/module/.

Name your template file with the following pattern: modularity-[module-id].php. You can get your module's id from the Modularity options page.

Module boilerplate

You can download our module boilerplate. It will be a good starting point for any custom module that you would like to build.

Module Attributes API

Some module features are available by setting certain attributes on the module's outmost element.

data-module-refresh-interval

Creates an interval on which the module is refreshed via XHR by calling the REST API. This attribute also requires that the data-module-id attribute is set on the same element.

The value of the attribute should be the number of seconds on which to run the refresh interval.

Example:

<div data-module-id="123" data-module-refresh-interval="60">
    This content will get refreshed every 60 seconds.
</div>

Rest API

The WordPress REST API is extended with the following endpoints.

modularity/v1/modules/{id}

This endpoint returns the markup for a specific module.

• Method: GET
• Params:
  • id: The ID of the module to retrieve.
• Response: The html markup of the module.

Upgrade

In some updates, database migrations might need to be run (will be in the release docs). To run the upgrade action on all sites in a multisite network, run the following command in the document root of your site.

wp site list --field=url --public=1 --archived=0 --deleted=0 --allow-root | xargs -n1 -I % wp modularity upgrade --url=% --allow-root

Or for a single site installation:

wp modularity upgrade

Constants

MODULARITY_DISABLE_FRAGMENT_CACHE

Disabling the built-in fragment cache means that each module's output will not be stored as an HTML cache. As a result, every time a visitor reloads the page, each module will have to be rendered again. However, it is important to consider this option only if you do not have any object cache enabled, such as Redis or Memcached. We strongly advise enabling the fragment cache feature in your application to enhance performance and caching efficiency, allowing modules to be rendered more quickly and reducing the need for repetitive rendering upon page reloads.

By defining this as true, cache will be turned off. Default: Undefined.

If enabled, each cached module will be rendered with a timestamp and cache ID in the following format:
