Atomic State Management: Why Nucleux Stands Out from Jotai and Zustand

State management in React has evolved dramatically. Gone are the days when Redux was your only choice for complex applications. Today's atomic state management libraries offer fine-grained reactivity, minimal boilerplate, and better performance. But which one should you choose?

The Rise of Atomic State Management

Traditional state management forces entire components to re-render when any part of the state changes. Atomic state management flips this approach - only components subscribed to specific pieces of state update when those pieces change.

This granular approach offers several key benefits:

• Performance: Eliminates unnecessary re-renders
• Simplicity: No complex provider trees or reducer boilerplate
• Scalability: Independent state atoms that don't interfere with each other
• Developer Experience: Intuitive APIs that feel natural to use

Popular Solutions: Jotai and Zustand

Jotai: Bottom-Up Atomic Approach

import { atom, useAtom } from 'jotai'

const countAtom = atom(0)
const nameAtom = atom('John')

function Counter() {
  const [count, setCount] = useAtom(countAtom)
  return <button onClick={() => setCount(c => c + 1)}>{count}</button>
}

Pros: True atomic approach, excellent for complex data relationships
Cons: Requires wrapping your app in a Provider, atoms scattered across files

Zustand: Simple Global Store

import { create } from 'zustand'

const useStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
}))

function Counter() {
  const { count, increment } = useStore()
  return <button onClick={increment}>{count}</button>
}

Pros: No providers needed, simple API, great for global state
Cons: Not truly atomic - all subscribers update when any state changes

Enter Nucleux: The Best of Both Worlds

Nucleux combines the atomic precision of Jotai with the simplicity of Zustand, while adding some unique advantages:

import { Store, useNucleux } from 'nucleux'

class CounterStore extends Store {
  count = this.atom(0)
  name = this.atom('John')

  increment() {
    this.count.value += 1
  }
}

function Counter() {
  const { count, increment } = useNucleux(CounterStore)
  return <button onClick={increment}>{count}</button>
}

Why Nucleux Wins

1. True Atomic Updates, Zero Providers

Unlike Jotai, Nucleux requires no providers. Unlike Zustand, it offers genuine atomic updates - only components using count re-render when count changes, not components using name.

2. Organized State Architecture

Instead of scattered atoms or monolithic stores, Nucleux uses classes to group related state and methods logically:

class TodoStore extends Store {
  todos = this.atom([])
  filter = this.atom('all')

  // Derived state that auto-updates
  filteredTodos = this.deriveAtom(
    [this.todos, this.filter],
    (todos, filter) => todos.filter(/* filter logic */)
  )

  addTodo(text) {
    this.todos.value = [...this.todos.value, { id: Date.now(), text }]
  }
}

3. Built-in Dependency Injection

Need one store to react to another? Nucleux makes it effortless:

class NotificationStore extends Store {
  userStore = this.inject(UserStore)
  notifications = this.atom([])

  constructor() {
    super()
    // Auto-load notifications when user changes
    this.watchAtom(this.userStore.currentUser, (user) => {
      if (user) this.loadNotifications(user.id)
    })
  }
}

4. Automatic Persistence

Save state to localStorage or AsyncStorage with zero boilerplate:

class UserStore extends Store {
  // Automatically persists to localStorage
  preferences = this.atom({ theme: 'dark' }, 'user-prefs')
}

5. Three Ways to Access State

Choose the right tool for each component:

// Just the methods
const store = useStore(TodoStore)

// Single atom value
const todos = useValue(TodoStore, 'todos')

// Everything at once
const { todos, filter, addTodo } = useNucleux(TodoStore)
