Local-first apps shift the user experience from waiting on the network to reconciling with it. The spinner becomes the exception, not the default.

Islands architecture keeps static HTML as the baseline and hydrates only the interactive parts. That split can reduce JavaScript cost without giving up rich UI.
Hydration can turn fast HTML into a slow interaction path. Zero-JS rendering and server components help teams reserve client JavaScript for where it is needed.
React Server Components can reduce client-side JavaScript when teams draw the right boundary between server-rendered data and interactive UI.
Design systems can improve consistency without bloating the frontend. Performance-aware tokens, components, and CSS choices keep interface reuse from becoming runtime cost.
Fast build pipelines depend on incremental work, clear dependency boundaries, and practical caching. Build strategy is now part of developer experience and release reliability.
Caching works best as a layered system across browser, server, CDN, and edge runtime. The hard part is keeping data fresh while avoiding unnecessary requests.
React Server Components move more rendering work off the client and reduce the JavaScript shipped to users. The benefit depends on data flow, boundaries, and caching strategy.
