Is it advisable to defer the loading of the cart on an e-commerce store until the page has been painted, to prevent script bottleneck?

Deferring the loading of the cart on an e-commerce store until the page has been painted can be a beneficial strategy to prevent script bottleneck and improve the overall performance of your website. By deferring the loading of the cart, you allow the essential elements of the page to load first, such as text, images, and other content, without causing delays due to the cart script.

Here are a few reasons why deferring the loading of the cart can be advisable:

1. Improved user experience: By deferring the cart loading, you ensure that users can start consuming the content of the page without waiting for the cart script to load. This improves the perceived performance of your website and provides a better browsing experience for users.

2. Faster page load times: Loading the cart script can potentially slow down the initial page load time, especially if the script contains heavy functionalities or makes multiple requests to external resources. By deferring the cart, you can prioritize the loading of crucial elements, reducing the overall time required to load the page.

3. Reduced script bottleneck: If the cart script is resource-intensive or relies on external dependencies, it can create a script bottleneck, where the execution of other scripts on the page is delayed or slowed down. By deferring the loading of the cart, you allow other scripts to run smoothly and minimize the potential performance impact.

To implement deferred cart loading, you can utilize techniques like lazy loading or asynchronous loading. Lazy loading defers the loading of resources until they are needed, while asynchronous loading allows scripts to load in the background without blocking the rendering of the page.

However, it's important to consider the specific requirements and functionalities of your e-commerce store before implementing deferred cart loading. Some factors to consider include the complexity of your cart script, any potential data dependencies, and the impact on user interactions (e.g., adding items to the cart). It's recommended to perform thorough testing and monitoring to ensure a smooth user experience and optimal performance.

Should I download and upload Google fonts as custom fonts to reduce the number of requests on my website?

While it is possible to download and upload Google fonts as custom fonts to reduce the number of requests on your website, it is generally not advisable, especially if you want to take advantage of the benefits offered by Google Fonts.

Here are a few considerations to help you make an informed decision:

1. Performance Impact: Using Google Fonts' CDN (Content Delivery Network) to load fonts provides several performance benefits, including faster loading times and optimized caching. By downloading and uploading custom fonts, you lose these benefits, as the fonts will be hosted on your server instead of Google's optimized infrastructure.

2. Variety and Availability: Google Fonts offers a wide range of font families and styles, ensuring compatibility across different devices and browsers. When you download and upload fonts as custom fonts, you might limit the available options and the overall design flexibility of your website.

3. Ease of Use and Updates: By using the standard Google Fonts API, you can easily integrate and manage fonts on your website by importing them through CSS. With custom fonts, you need to manually handle the font files, ensuring compatibility, implementing font formats, and managing updates and versioning.

If reducing the number of external requests on your website is a primary concern, there are alternative strategies to consider. One option is to use font subsetting, which allows you to include only the characters and styles you need in your font files, reducing file size and optimizing performance. Another option is to self-host fonts, where you host the font files on your server, ensuring control over their delivery while still benefiting from the use of web font formats like WOFF2.

In summary, while downloading and uploading Google fonts as custom fonts may reduce the number of requests on your website, it often comes with trade-offs in terms of performance, variety, ease of use, and updates. Carefully evaluate your specific needs and consider alternative optimization techniques before making a decision.
