Video is everywhere on the web, from hero banners to product videos to full-blown streaming. However, while Lighthouse reports issues related to images, scripts, and more, it doesn't really address video performance. That means streaming can suffer for end users, resulting in buffering and slow starts, while businesses incur huge data transfer costs due to unoptimized delivery.
In this lightning talk, we'll explore some quick wins every developer should know: optimizing video size and format, optimizing streaming for every device and network, and different video loading strategies to improve performance. In just seven minutes, you'll leave with a toolkit to make your videos load faster, play smoother, and feel as polished as the rest of your app, closing a significant gap that performance audits often overlook.
This talk has been presented at React Summit US 2025, check out the latest edition of this React Conference.
