TopicsPerformance Architecture
Part of the Frontend Developer Roadmap.
Summary
Making performance a first-class architectural concern — rendering strategy, code splitting boundaries, and data-fetching patterns chosen upfront rather than patched in later.
How to Learn This
- 1Decide your rendering strategy (SSR/SSG/CSR) per route before building it, not after.
- 2Set a performance budget (e.g. bundle size, LCP target) for the project.
- 3Review architectural decisions periodically against real Lighthouse/Web Vitals data.
