Type-safe Zustand stores leverage generics and type inference to ensure compile-time safety. Define a store interface, use generic constraints to enforce shape, and apply type predicates for runtime validation. This prevents state mutation errors and enables IDE autocompletion across your PRISM.node editor workflow.

Conditional types enable type-level logic—inferring one type based on another. Use them to build flexible APIs that adapt behavior based on input types, extract nested types from libraries, and create overloaded function signatures. They're essential for scaling reusable components without sacrificing type safety.

Utility types transform existing types to create derived versions: Partial makes properties optional, Pick selects a subset, Omit removes fields, and Record maps keys to values. Apply them to reduce duplication, enforce constraints on component props, and adapt external types for internal use.

Generic components accept type parameters with constraints, enabling single implementations to work across multiple data shapes. Define a base interface, use type bounds to restrict allowed inputs, and leverage mapped types to transform properties. This scales PRISM.node components without code duplication.

Yes—use the `typeof` operator and conditional type inference to extract types from library exports. Apply `ReturnType`, `Parameters`, or custom type predicates to derive accurate types. This ensures your PRISM.node integrations remain type-safe even when third-party APIs change.

Type guards narrow types at runtime; type predicates are functions returning `arg is Type` that signal type narrowing to TypeScript. Use predicates to validate Zustand store state, filter arrays by type, and enforce runtime contracts. Both are critical for bridging compile-time safety and runtime behavior.
