Load Only Necessary WordPress Block Assets

Uncategorized

Hello, WooCommerce enthusiasts!

If you’ve found your way to this post, you’re probably already familiar with the exceptional platform that is WooCommerce – a user-friendly, customizable e-commerce solution built on WordPress. While it’s a fantastic tool, as with any complex system, there can sometimes be inefficiencies. This blog post will delve into one of these areas and present an optimization strategy that can help your WooCommerce store run smoother and faster: Loading only necessary WordPress block assets.

Before we dive into the heart of the matter, let’s take a moment to understand the role of block assets in WordPress.

WordPress Block Assets and Their Role

Block assets in WordPress are scripts and styles that each block type in the Gutenberg editor uses. Each of these blocks – from Paragraph to Image, from Gallery to Quote – have their own scripts and styles, collectively called block assets. These block assets are loaded on every page where the block library is loaded, even when you’re not using all the block types. This can slow down your site, even when you’ve optimized it in other ways.

The Solution

To address this, WordPress introduced a filter should_load_separate_core_block_assets in WordPress 5.8. This filter allows you to control how and when the block assets are loaded, providing an opportunity to optimize the loading of block assets and, thus, improve the overall speed of your WooCommerce site.

To use this filter, you simply add the following line of code to your theme’s functions.php file:

phpCopy codeadd_filter( 'should_load_separate_core_block_assets', '__return_true' );

This line of code tells WordPress to load only the assets for the blocks used on each page, instead of loading the assets for all blocks. This way, you’re making sure that only the necessary scripts and styles are loaded, thus speeding up your site.

Impact and Limitations

The impact of this code is profound. You can expect a decrease in the number of HTTP requests and an overall reduction in the page size, leading to faster loading times.

However, keep in mind that this optimization does not apply to third-party blocks, only the core WordPress blocks. Also, if your server is using HTTP/2, the speed improvement might be less noticeable as HTTP/2 is designed to handle multiple small files more efficiently.

Wrapping Up

In the world of e-commerce, every second counts. Faster page loads can improve user experience, SEO ranking, and ultimately, conversions and sales. By taking advantage of the should_load_separate_core_block_assets filter in WordPress, you’re taking a step towards enhancing your WooCommerce store’s performance.

Remember that this is just one aspect of optimization. To truly harness the full potential of your WooCommerce store, you should consider other optimizations too, such as image compression, caching, and using a quality hosting provider.
