How Vercel adopted microfrontends

This post details Vercel's internal migration from a monolithic Next.js application to a vertical microfrontend architecture for its main website. It explains the rationale behind the migration (improving build times, developer velocity, and dependency management), the choice of vertical microfrontends over horizontal ones, and the incremental migration path using Next.js Multi-Zones and feature flags. The post highlights the benefits achieved, such as over 40% improvement in preview build times and local development compilation, and reduced page weight. It also touches upon leveraging Turborepo and Turbopack for build optimizations.
