The New York Times recently upgraded its website to React 18, aiming to enhance performance and access new features. The upgrade introduced Concurrent Mode for smoother rendering, automatic batching for optimized performance, and new functionalities like server-side rendering. The move was crucial for improving Interaction to Next Paint scores, a key metric for search engine ranking. The migration process involved removing deprecated dependencies, upgrading major components, and integrating React 18 features like createRoot and hydrateRoot. However, challenges arose with highly trafficked content called "embedded interactives," impacting the site's performance. These interactives, rendered server-side with dangerouslySetInnerHTML, posed issues due to React 18's stricter hydration requirements. The team had to address script load ordering and execution nuances to ensure these interactive elements functioned correctly post-upgrade. Despite the hurdles faced, the React 18 upgrade ultimately led to significant performance gains and opened doors for future improvements on The New York Times website.
