NextFaster is a high-performance e-commerce template built with Next.js 15, designed to demonstrate the capabilities of Partial Prerendering (PPR), server actions, and the Vercel platform. It features over 1 million AI-generated art supply products with categories, subcategories, and product pages. The application uses Drizzle ORM on Neon Postgres for data storage, Vercel Blob for image hosting, and Upstash for rate limiting. Authentication is handled via JWT sessions with bcrypt password hashing. The architecture follows a monolithic Next.js app router pattern with server actions for all mutations (cart, auth). Pages are rendered using PPR: the static shell is precomputed and served from the edge, while dynamic data (cart count, user state) is streamed in. The site leverages Incremental Static Regeneration (ISR) for caching product pages and uses a custom prefetching system that preloads images on link hover via an API route that parses target page HTML. Key features include a search dropdown with full-text search (tsvector) and ILIKE fallback, a cookie-based cart, user authentication with sign up/sign in, and an order page with cart summary. The codebase demonstrates advanced Next.js patterns including React 19's useActionState, Radix UI primitives for accessible components, and the Effect library for concurrent data generation scripts.
