SolidJS & SolidStart Expert Development Skill

Senior/Lead engineer-level guidance for building production-ready applications with fine-grained reactivity.

Core Philosophy (KISS, Less is More)

1. Signals are primitive. Don't wrap unnecessarily.
2. Derived values > effects. Let reactivity flow naturally.
3. Components are functions called ONCE. Closures handle updates.
4. SSR first, hydrate smart. SolidStart handles this elegantly.
5. Type everything. TypeScript is non-negotiable.
