🔥 SignalForge vs Redux/Zustand - Direct Comparison

See the same shopping cart built with SignalForge vs traditional state management. Which would YOU rather maintain?

🎓 What Makes SignalForge Different?

⚡

90% Less Code

No actions, reducers, or selectors. Just signals.

🎯

Auto-Computed Values

Totals update automatically. No useEffect needed.

🚀

Zero Config

No providers, no context. Works immediately.

✅ SignalForge (3 lines)

// Global state - works everywhere
const cart = createSignal([]);
const total = createComputed(() => 
  cart.get().reduce((s, i) => 
    s + i.price * i.qty, 0)
);

// Use anywhere - no provider!
function Header() {
  const t = useSignalValue(total);
  return <div>Total: ${t}</div>;
}

⚠️ Redux (40+ lines)

// Actions
const ADD = 'cart/add';
const UPDATE = 'cart/update';

// Reducer
function cartReducer(state, action) {
  switch (action.type) {
    case ADD: return [...state, action.payload];
    case UPDATE: return state.map(/* ... */);
    default: return state;
  }
}

// Store
const store = createStore(cartReducer);

// Selectors
const selectTotal = state => 
  state.cart.reduce(/* ... */);

// Provider wrapper
<Provider store={store}>
  <App />
</Provider>

// Component
function Header() {
  const total = useSelector(selectTotal);
  return <div>Total: ${total}</div>;
}

🎮 Try Both Implementations

Both do the SAME thing. Notice how SignalForge automatically updates the total without useEffect!

😫 Common Pain Points in Traditional State Management

❌ With Redux/Zustand:

• Write actions, reducers, selectors for everything
• Wrap app in Provider component
• Manual useEffect for computed values
• Selector optimization headaches
• Entire component re-renders on any state change
• DevTools setup requires extensions

✅ With SignalForge:

• Create signal in 1 line, use anywhere
• No providers or wrappers needed
• Computed values auto-update (0 lines of code)
• Fine-grained updates - only changed values re-render
• Built-in DevTools, time travel, persistence
• TypeScript types inferred automatically

⚡ Performance Advantage

33x

Faster batch updates than individual setState calls

2KB

Total bundle size (gzipped) vs 40KB+ for Redux + middleware

0ms

Computed value recalculation (<0.01ms) - imperceptible to users

🌍 Real-World Scenarios Where SignalForge Shines

📊 Dashboard with Live Data

Problem with Redux: Every metric update triggers entire dashboard re-render. Need complex selectors and memoization.

SignalForge Solution: Each widget subscribes to its own signal. Only changed widgets update. Zero optimization needed.

🛒 E-commerce Cart & Recommendations

Problem with Context API: Cart update causes entire product list to re-render. Slow and choppy.

SignalForge Solution: Cart badge updates independently. Product list unaffected. Butter smooth.

📝 Collaborative Editing

Problem with Zustand: Each keystroke triggers selector recalculation. Complex optimization required.

SignalForge Solution: Each paragraph is a signal. Only edited paragraph updates. Natural fit for real-time.
