With Stock Dependencies for WooCommerce, you can make the products and 
variations in your WooCommerce store dependent on the inventory of your other 
products or variations. Customers will be able to select and purchase the 
product without seeing the products on which it depends in their cart, during 
their checkout, or on their receipt. Inventory management in Woo Commerce is 
greatly simplified since you only have to manage inventory levels for the 
item(s) on which your product or variation is dependent.
Stock Dependencies for WooCommerce works for Simple and Variable product types 
in WooCommerce and you can make a product or variation dependent on a 
combination of other products and variations. Stock Dependencies for WooCommerce 
lets you create dependencies on quantities of one or more of the other products.
Stock Dependencies for WooCommerce is ideal for:
<ul>
<li>Selling products in multiple quantities. For an product you already have in 
your inventory, you can use Stock Dependencies for WooCommerce to sell, for 
example, a package of six items and and package of 12 items. With Stock 
Dependencies for WooCommerce you do not need to maintain inventory levels for 
each quantity of the product as the product inventory is managed for only the 
single quantity item.</li>
<li>Selling bundled products. You can create a bundle of 
multiple items and sell them as a single item. With Stock Dependencies for 
WooCommerce your customers will only see the bundle product in their cart, 
during the checkout process, and on their order receipt.</li>
</ul>
When a product with stock dependencies is displayed in your store, Stock 
Dependencies for WooCommerce will check the inventory of the products on which 
it depends and will only show the product as being available if all the 
dependent stock items are available. When a product with stock dependencies is 
added to a shopping cart and eventually purchased, the customer will only see 
the single product in their cart and order, and will not see the products on 
which it is dependent. When the product is purchased, Stock Dependencies for 
WooCommerce will reduce the inventory of the items on which it is dependent by 
the appropriate amount.
<h3>Configuring</h3>
Stock Dependencies for WooCommerce is easy to configure for any simple or 
variable product in your WooCommerce store. A single checkbox is added to each 
simple product or variation in your WordPress admin that allows you to enable 
stock dependencies for that product or variation. Once checked, two fields are 
added for the SKU and the quantity of the dependency. Additional dependencies 
can be easily added.
<h3>Shopping</h3>
When a customer views a product with dependencies in your WooCommerce store, 
they will see the product as you have configured it, but the available quantity 
and in-stock status will be determined by Stock Dependencies for WooCommerce 
from the available quantities of each of the products and variations on which it 
is dependent.
<h3>Cart, Checkout, and Receipt</h3>
Customers will only see the product they selected, and not the products upon 
which it is dependent, in their shopping cart, during the checkout process, and 
on their receipt.
<h3>Restocking Refunds and Cancelled Orders</h3>
When you issue a refund or cancel an order that has stock dependencies, the 
plugin will restock the dependency products.
<h3>Privacy</h3>
The Stock Dependencies for WooCommerce plugin does not affect the way personal 
information is collected or stored within your WooCommerce store or your 
WordPress installation.
<h3>Open Source</h3>
The Stock Dependencies for WooCommerce plugin is open source software. Feel free 
to contribute or fork this code on

This plugin takes all scripts and stylesheets that have been added via <code>wp_enqueue_script</code> and <code>wp_enqueue_style</code> 
and automatically concatenates and minifies them into logical groups. For example, scripts in the footer get grouped 
together and styles with the same media (e.g. <code>print</code>) get minified together. Minification is done via WP-Cron in order 
to prevent race conditions and to ensure that the minification process does not slow down page responses.
This is a reincarnation and rewrite of the <a href="https://wordpress.org/plugins/optimize-scripts/" rel="ugc">Optimize Scripts</a> plugin, 
which this plugin now supersedes.
Features:
<ul>
<li>Minified sources are stored in the WP Options table so no special filesystem access is required.</li>
<li>Endpoint for minified requests is at <code>/_minified</code>, which can be configured.</li>
<li>Admin page for taking inventory of minified scripts and stylesheets, with methods for expiring or purging the cached data.</li>
<li>Dependencies which must not be minified may be excluded via the <code>dependency_minification_excluded</code> filter.</li>
<li>Dependencies hosted on other domains are by default excluded, but this behavior can be changed by filtering the <code>default_exclude_remote_dependencies</code> option via the <code>dependency_minification_options</code> filter, or on a case-by-case basis via the filter previously mentioned.</li>
<li>By default excludes external scripts from being concatenated and minified, but they can be opted in via the <code>dependency_minification_excluded</code> filter.</li>
<li>The length of time that a minified source is cached defaults to 1 month, but can be configured via the <code>cache_control_max_age_cache</code> option.</li>
<li>If a minified source is not available yet, the page source will note that the dependency minification process is pending.</li>
<li>Any errors that occur during minification will be shown on the frontend in comments if the <code>show_error_messages</code> option is enabled; such errors are enabled by default if <code>WP_DEBUG</code>.</li>
<li>If the minification process errors out, the original unminified sources are served and the error is cached for 1 hour (by default, configured via <code>cache_control_max_age_error</code>) to prevent back-to-back crons from continually attempting to minify in perpetuity.</li>
<li>Cached minified sources are served with <code>Last-Modified</code> and <code>ETag</code> responses headers and requests will honor <code>If-None-Match</code> and <code>If-Modified-Since</code> to return <code>304 Not Modified</code> responses (configurable via the <code>allow_not_modified_responses</code> option).</li>
<li>Data attached to scripts (e.g. via <code>wp_localize_script</code>) is also concatenated together and attached to the newly-minified script.</li>
<li>WP-Cron is utilized to initiate the minification process in order to prevent race conditions, and to ensure that page responses aren’t slowed down.</li>
<li>Stale minified scripts and stylesheets remain until replaced by refreshed ones; this ensures that full-page caches which reference stale minified sources won’t result in any 404s.</li>
<li>Can serve compressed responses with <code>gzip</code> or <code>deflate</code>.</li>
<li>Transforms relatives paths in stylesheets (e.g. background-images) to absolute ones, so that they don’t 404.</li>
</ul>
Development of this plugin is done <a href="https://github.com/x-team/wp-dependency-minification" rel="nofollow ugc">on GitHub</a>. Pull requests welcome. Please see <a href="https://github.com/x-team/wp-dependency-minification/issues" rel="nofollow ugc">issues</a> reported there before going to the plugin forum.
If you are using Nginx with the default Varying Vagrant Vagrants config, you’ll want to remove <code>css|js</code> from this rule in <code>nginx-wp-common.conf</code> (or remove the rule altogether):
<pre><code># Handle all static assets by serving the file directly. Add directives 
# to send expires headers and turn off 404 error logging.
location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
 expires 24h;
 log_not_found off;
}
</code></pre>

Dependency Minification

Automatically concatenates and minifies any scripts and stylesheets enqueued using the standard dependency system.
