- Metaframeworks handle complexity (Next.js, Nuxt, SvelteKit, SolidStart, Analog)
- Streaming SSR becoming standard
- Hybrid rendering (SSG + SSR) common
Reactivity Models Converging
- Signals pattern appears in Vue Vapor, Angular, Svelte Runes, Solid
- Fine-grained reactivity as goal
- Less re-rendering, more precise updates
TypeScript Everywhere
- First-class TypeScript in all frameworks
- Type inference improvements
- Better IDE support
Migration Considerations
React to Solid
- Easiest migration (similar syntax)
- Different mental model (no re-renders)
- Rewrite components with reactive primitives
React to Svelte
- Different syntax requires rewrite
- Simpler code often results
- Performance gains significant
Vue to React or vice versa
- Different philosophies
- Component-by-component migration possible
- Tooling and ecosystem shift
Future Outlook
Next 12-24 Months
- Server components pattern spreading beyond React
- Signals-based reactivity becoming standard
- Performance gaps narrowing
- Framework interoperability improving (Web Components)
- AI-assisted development for all frameworks
- Build tools reaching near-instant
Consolidation vs Fragmentation
