Rendering strategy selection depends on your route's content volatility, SEO needs, and performance targets. SPA suits interactive, user-specific content; SSR balances interactivity with SEO; SSG works for static content; ISR and RSC offer hybrid approaches. Assign a strategy per route based on these trade-offs, document the decision in an ADR, and define explicit boundaries to align team ownership.

Distinguish between local, shared, global, server, and URL state, then define caching and invalidation strategies for each. Plan how data flows through routes and modules, establish fetch boundaries, and document patterns in architecture artifacts. This prevents state collisions and enables independent team scaling.

Create Architecture Decision Records (ADRs) for major choices: rendering strategy per route, data fetching approaches, state boundaries, and module interfaces. Produce route maps and module diagrams as shared artifacts. This aligns teams, accelerates implementation, and makes trade-offs explicit and revisable.

Define performance budgets, accessibility standards, security posture, observability requirements, and delivery pipelines upfront. These concerns shape routing, state handling, and module boundaries. Document trade-offs between performance, user experience, and team velocity in your architecture artifacts.

Yes. Explicit module boundaries, ADRs, and artifact-driven ownership enable distributed teams to work independently. Clear state and data boundaries prevent coordination overhead. Define which team owns which route and module, then use checklists and evaluation criteria to maintain consistency as you scale.

CSR maximizes interactivity but delays SEO; SSR ensures SEO and faster first paint but increases server load; SSG offers best performance for static content; ISR and RSC enable hybrid strategies. Trade-offs span Time to First Byte, Time to Interactive, server cost, and content freshness. Choose per route based on your performance budget and user profile.
