RSC made our site much faster

React Server Components (RSC) enhance web applications by allowing secure server-side API calls and efficient client-side browser API use, thus optimizing code by reducing server-only dependencies in client bundles. A case study conducted on productonboarding.com using Next.js and RSC demonstrated a 62% reduction in bundle size and a 63% improvement in Google's Speed Index compared to a non-RSC version, showcasing the significant performance advantages of RSC. The experiment utilized Vercel for deployment and various performance tests, revealing that while the RSC version's served page size increased, it achieved a quicker first contentful paint than its client-side counterpart. With the Frigade React SDK now compatible with RSC, there is an anticipated growth in demand for RSC-compatible libraries as developers seek to reduce their bundle sizes dramatically.
