summary

Covers using React 18’s Suspense API to avoid hydrating every server-rendered component by dynamically loading and hydrating components only when they enter the viewport. Describes the practical approach Wix used—promise-based Suspense rendering plus viewport-triggered hydration—to reduce JavaScript execution and improve interaction times, with a technical deep dive and code examples.
