Migrate a large, open-source React application to Next.js and Vercel

This post details the incremental migration of a large, open-source React application (BBC website) to Next.js and Vercel. Key technical contributions include: setting up Next.js with Emotion, configuring Webpack for import aliases and timezone data handling, adapting to Next.js's routing and data fetching mechanisms (getInitialData), and leveraging Vercel's preview deployments. The migration resulted in significant code reduction and improved local development iteration speed.
