Why React Vite Apps in 2026 Don’t Fail on Bundle Size
React Vite apps lose Core Web Vitals not on bundle size, but in the moment of first render. Teams who chase Lighthouse scores build for the build system, not the eye—and trust is lost at launch.
React Vite apps reach strong Core Web Vitals in 2026 only if rendering is treated as an architecture strategy, not a checklist of isolated fixes. What matters is controlling what’s visible first, the priority of blocking tasks, and the layout contract before data lands—not just toolchain upgrades. The truth is in the production rendering chain, not the output directory.
