Easy Steps for Removing Unused Javascript in Shopify

Are you tired of cluttered code in your Shopify store? Have you ever wondered why your website is loading slower than usual? You might have unused Javascript lying around, taking up valuable space and slowing down your site’s performance.

But don’t worry, we’ve got you covered! In this blog post, we will guide you through the steps for removing unused Javascript from your Shopify store. Say goodbye to cluttered code and hello to a faster loading website!

What is Unused Javascript?

Unused Javascript refers to the code that is present in your Shopify store but not being used or executed. This can occur due to several reasons such as changes in the theme, removal of apps or simply outdated features.

It’s important to note that unused Javascript can cause various issues for your website including slower page load times and increased server requests which ultimately affects user experience.

For example, imagine a customer visiting your online store and trying to purchase a product but the checkout process takes an abnormally long time due to unnecessary scripts running on the backend. This could lead them to abandon their cart and look elsewhere.

Therefore, it is crucial for every Shopify store owner who cares about their website performance and user experience, to regularly remove any unused Javascript from their website.

Why Remove Unused Javascript?

Removing unused Javascript from your Shopify website is not just a matter of optimizing website performance; it has several other benefits. For instance, having too much unused code can be detrimental to the user experience, as it makes pages load slower than necessary. Slow loading times are one of the primary causes of high bounce rates and low conversions.

Furthermore, removing excess Javascript from your site can simplify its structure significantly. This simplification process will make debugging any issues that arise in the future much easier and more straightforward since there will be less code to sift through.

Another benefit of removing unused Javascript is reducing security risks on your website. Unused code creates an attack surface for hackers who could exploit vulnerabilities in that code to gain access or control over your site’s functionality.

In summary, there are many reasons why you should remove unused Javascript from your Shopify website. Doing so can improve page speed, enhance user experience, simplify maintenance processes and reduce potential security threats on your site.

How to Remove Unused Javascript from Shopify

Removing unused Javascript from Shopify is a crucial step to optimize your website’s performance. The first thing you need to do is identify the unused Javascript on your website by analyzing its codebase. You can either manually search for it or use online tools that scan your website and provide a detailed report of all the unused scripts.

Once you have identified the unused Javascript, simply remove it from your Shopify theme files. It’s essential to make sure that you don’t accidentally delete any important scripts while removing them. Therefore, always make backups of your theme files before making any changes.

Another way to ensure that you’re not removing necessary code is by using conditional logic in your theme files. This allows specific scripts to load only when they’re needed, reducing the amount of unnecessary code on each page and improving site speed.

Regularly review and update your website’s codebase as new features or updates are added over time. By keeping an eye out for unnecessary codes, you’ll be able to keep optimizing the performance of your Shopify store and improve customer experience overall.

Tools for Identifying and Removing Unused Javascript

When it comes to identifying and removing unused Javascript from your Shopify store, there are several tools available that can help make the process easier. These tools are specifically designed to scan your website’s code and identify any lines of Javascript that aren’t being used.

One popular tool for identifying unused Javascript is Google’s Chrome DevTools. This free tool allows you to inspect individual elements on your web page, view the associated code, and see which scripts are actually being executed.

Another useful tool for identifying unused Javascript is Lighthouse. This open-source project provides automated audits for performance, accessibility, and other best practices in web development. It can also generate a report on which scripts aren’t being used so you can remove them quickly.

If you’re looking for an all-in-one solution for optimizing your Shopify store’s performance, then consider using a dedicated app like NitroPack or Script Optimizer by Space Squirrel. These apps will automatically detect and remove any unnecessary code from your website without requiring manual intervention.
