What does an effective frontend architecture include?

An effective frontend architecture includes a component library built in a design-to-code workflow (Figma to React or Vue components), a consistent state management strategy (using tools like Redux, Zustand, or React Query for data fetching and caching), and a clearly defined rendering strategy (SSR, SSG, or ISR in Next.js depending on content update frequency and SEO requirements).

It also includes a design token system that maps brand colors, typography, and spacing from the design system into CSS custom properties or a framework like Tailwind CSS, ensuring visual consistency is enforced at the code level rather than relying on developer discipline. A component testing setup using Jest and React Testing Library, a visual regression testing tool like Chromatic, and a performance budget enforced through Lighthouse CI in the deployment pipeline complete a frontend architecture that supports both development velocity and production reliability.
