The new Next.js Commerce 2.0 is a highly performant, dynamic storefront that leverages the latest features of Next.js 13 and Vercel's Frontend Cloud to achieve incredible performance. It introduces a caching architecture in the App Router, which enables server-rendered storefronts to feel static while still being dynamic. The new version also includes React Server Components, Streaming, and Suspense, allowing for more control over when and where to serve static or dynamic content. Additionally, it features Edge Runtime, which allows for fast web access regardless of location by running code close to visitors. With Server Actions, server-side data mutations can be colocated with the UI that invokes them, reducing client-side JavaScript and bundle size. Next.js Commerce 2.0 has also simplified its architecture, removing roughly 145,000 lines of code from the previous version, making it more maintainable and easier to understand. The new version is designed for highly dynamic ecommerce sites and provides a better ecommerce experience with features such as dynamic storefronts, improved performance, and reduced latency.
