summary

Walks through modernizing a demo React app by incrementally replacing old patterns (heavy effects, memoization) with React 19+ features: the stable React Compiler, the new useEffectEvent hook, the <Activity /> API, and improved SSR primitives like Partial Prerendering. Demonstrates concrete code changes and upgrades applied step by step to the example app.
