JavaScript Optimization Techniques For Speed Up Magento 2 Website

Now the major concern is how to speed up Magento 2 website? Well, fear as you will discover the best tips that will help you skyrocket your website’s speeds.

Unleash the Caching Wizardry 

One of the simplest ways to speed up your Magento 2 website is caching! By enabling full-page caching, you’ll drastically reduce the time it takes to load your web pages. You may embrace Magento’s built-in caching mechanisms and get magical results. When your customers experience lightning-fast loading times, they’ll feel content and come for more.

Minify the Codes

Another helpful technique is to cast the minification spell on your JavaScript, CSS, and HTML files! When you minify these codes, you can strip them of unnecessary spaces and comments, making them sleek and efficient. And right after that, you should bundle your magical scripts together to minimize the number of requests and deliver them as one powerful package.

Enchant Images with Lazy Loading

Images hold the power to capture hearts and imagination, but they can also slow down your website’s performance.

By using the sorcery of lazy loading, images will only load when they’re about to appear on the screen, conserving precious loading time. As a result, your customers will be entranced by the seamless experience as they browse through your website’s pages.

Optimize Code For JavaScript and CSS 

Weave a performance-enhancing spell on your JavaScript and CSS files! Tame and eliminate any unused code or styles, as they can weigh down your website’s performance like heavy chains.

Embrace tree shaking for JavaScript to remove unnecessary branches and employ CSS minification for leaner, meaner styles. As a result, your web pages will dance gracefully across the digital realm, feeling as light as a feather.

Utilize the Power of Content Delivery Networks.

You may utilize the power of Content Delivery Networks (CDNs) to distribute your website’s resources across the globe. By strategically placing these enchanting mirrors on your site, your visitors can access the content from the nearest CDN server.

This technique boosts loading times and ensures a delightful experience for users, no matter where they wander in the vast online offerings.

Embrace the Async and Defer 

You can unleash the magic of async and defer attributes on your JavaScript spells.

Applying these attributes ensures that certain scripts load asynchronously or after the page has fully loaded.

This allows your website to render faster, preventing scripts from locking the loading process. As if by sorcery, your customers will enjoy a seamless browsing experience, free from interruptions, like attending a mesmerizing firework display.

Consider Compilation

Once upon a time, compilation was the norm for Magento 2 websites. But as technology advances, its enchanting capabilities are more likely to be forgotten.

Nevertheless, you can still rediscover its power. Your website will transform into a speed-optimized marvel by enabling JavaScript and CSS compilation. Every time a customer visits your site, the spells will have already been cast, delivering a swift and delightful experience from the first click.

Audit and Monitor

Just like every machinery needs a skillful technician to ensure smooth operations, the same case applies here. Your Magento 2 website needs your watchful eye. So make sure to regularly audit and monitor your site’s performance, using tools like Lighthouse or PageSpeed Insights, and fine-tune accordingly.
