Reactive state management across React and Vue uses framework-agnostic store primitives with specific adapters to bind values to the UI. You create a central Store and use corresponding hooks or composables for React, Vue, Solid, Angular, or Svelte to ensure automatic UI updates.

Building derived computations for reactive state involves chaining Derived instances to create transformations like filter, sort, and paginate. You mount these instances to activate reactivity, ensuring computed values update automatically when the underlying central Store data changes.

Batch in immutable state updates groups multiple Store modifications together for atomic updates and coordinated compositions. This ensures derived computations and UI renders trigger only once after the batch completes, preventing intermediate inconsistent states.

Handling reactive side effects with signals-like stores uses the Effect primitive, which supports optional lifecycle cleanup. You mount the Effect instance to activate reactivity, allowing it to execute side effects and run cleanup functions when dependencies change or the instance unmounts.

TanStack Store works without a specific UI framework by providing framework-agnostic immutable reactive state primitives. Core Store, Derived, Effect, and batch functionalities operate independently, while framework adapters are optionally available for binding to React, Vue, Solid, Angular, and Svelte.

A signals-like store for app-level data is not suited for scenarios requiring heavy relational data persistence or complex schema validation. It targets reactive application state, derived views, and lifecycle side effects, rather than serving as a full database replacement.
