Description
Faster and cheaper websites: integrating next-gen images in your Rails apps by JP Balarini Did you know loading images accounts for nearly 50% of your website’s total load time? Also, every additional second of load time results in a 5% decrease in conversion rates, which directly impacts your business. What if I told you there’s a simple way to decrease loading time? This talk will explore the latest and most effective options for web images that significantly reduce website size without compromising quality. We’ll discuss how using next-gen images can significantly impact website loading times, user conversion, and SEO. We’ll also go through the different challenges that I faced while integrating next-gen images into a Rails project and how I solved them. A new gem will be presented that streamlines the process of using WebP images with Ruby on Rails.

In the talk titled "Faster websites: integrating next-gen images in your Rails apps," JP Balarini discusses the critical role of image loading times in overall website performance and business conversion rates. He highlights that images account for nearly 50% of a site’s load time, leading to a 5% drop in conversions for every additional second it takes to load. Key points discussed include: - **Importance of Image Formats**: Traditional formats like JPEG and PNG are being replaced by next-gen formats such as WebP and AVIF that provide better compression without compromising quality. WebP is especially noted for its compatibility across most modern browsers. - **Performance Metrics**: Balarini presents compelling statistics from various studies showing that websites loading in under two seconds yield significantly higher conversion rates. Companies like Telefonica and BMW have seen marked improvements in click-through rates after improving their loading times. - **SEO Implications**: Faster-loading websites rank better in search engine results, as loading time is a recognized ranking signal by Google. Therefore, optimizing image loading is not just a technical issue but also has direct repercussions for online visibility. - **Cost Efficiency**: Optimizing image sizes can lead to substantial savings in storage and transfer costs, notably for platforms with high usage like Instagram, which processes vast amounts of data daily. - **Integrating Next-Gen Images in Rails**: Balarini discusses the challenges of integrating WebP images or using picture tags in Rails applications, given that Rails does not natively support these formats. He details the shortcomings of existing gems and the need for a custom solution, which led to the development of a new gem for streamlining this integration. - **Example of Implementation**: He shows how to configure Rails applications to automatically convert and serve WebP images, using a combination of Rake tasks and helper methods for both static and dynamic assets. In conclusion, by integrating next-gen image formats into Rails applications, developers can significantly reduce load times, improve SEO, and enhance the user experience while also saving costs. Balarini encourages the audience to contribute to developing better solutions for common challenges faced in web development, particularly within the Rails ecosystem.
