NuclearJS is a reactive Flux state management library built on ImmutableJS data structures, with all application state in a single immutable map. It is framework agnostic, using functional 'getters' for derived state and offering integrations with React and Vue.

Use cases

• manage application state with immutable data structures
• implement Flux architecture in a JavaScript app
• build reactive dataflow between stores and React or Vue views
• keep all app state in a single debuggable immutable map
• derive and compose state without stores referencing each other
• run Flux state logic on a Node.js server without a UI

When to choose

• you want immutable, functional Flux-style state management decoupled from any UI framework
• you prefer a single immutable state map with declarative stores and composable getters
• you need state logic that runs identically on server and client

When to avoid

• you are starting a new project where modern solutions like Redux, Zustand, or MobX are better supported
• you need a library with active development and a large current community
• you want built-in async action handling or modern ecosystem tooling
