React Signify vs Other State Management Libraries
React Signify is a modern state management library built on the Signal Pattern. Let's compare it with other popular solutions to understand React Signify's superior advantages.
React Signify vs Redux
Overview Comparison
Criteria | React Signify | Redux |
---|---|---|
Boilerplate Code | Extremely minimal | Very heavy |
Learning Time | 5-10 minutes | Hours/Days |
Bundle Size | ~4KB | ~10KB+ (with Redux Toolkit) |
DevTools | Built-in | Requires extension |
TypeScript | Fully automatic | Manual configuration required |
Performance | Automatically optimized | Manual optimization required |
Time to Value | Instant | Complex setup required |
Detailed Comparison
1. Code Complexity (Boilerplate)
Redux - Overly Complex:
// ❌ Redux - Requires tons of code
// Action Types
const INCREMENT = 'counter/increment';
const DECREMENT = 'counter/decrement';
const SET_USER = 'user/setUser';
// Action Creators
const increment = () => ({ type: INCREMENT });
const decrement = () => ({ type: DECREMENT });
const setUser = (user) => ({ type: SET_USER, payload: user });
// Reducers
const counterReducer = (state = 0, action) => {
switch (action.type) {
case INCREMENT: return state + 1;
case DECREMENT: return state - 1;
default: return state;
}
};
const userReducer = (state = null, action) => {
switch (action.type) {
case SET_USER: return action.payload;
default: return state;
}
};
// Store setup
const store = createStore(combineReducers({
counter: counterReducer,
user: userReducer
}));
// Provider setup
function App() {
return (
<Provider store={store}>
<MyComponent />
</Provider>
);
}
// Component usage
function MyComponent() {
const counter = useSelector(state => state.counter);
const user = useSelector(state => state.user);
const dispatch = useDispatch();
return (
<div>
<span>{counter}</span>
<button onClick={() => dispatch(increment())}>+</button>
<span>{user?.name}</span>
</div>
);
}
React Signify - Simple:
// ✅ React Signify - Just a few lines
import { signify } from 'react-signify';
// Create state
const sCounter = signify(0);
const sUser = signify(null);
// Use directly, no Provider needed
function MyComponent() {
const counter = sCounter.use();
const user = sUser.use();
return (
<div>
<span>{counter}</span>
<button onClick={() => sCounter.set(prev => prev.value += 1 )}>+</button>
<span>{user?.name}</span>
<button onClick={() => sUser.set({ name: 'John' })}>Set User</button>
</div>
);
}
2. Performance & Re-render Optimization
Redux - Manual optimization required:
// ❌ Redux - All connected components re-render
const MyComponent = () => {
// This component will re-render when ANY part of store changes
const { user, cart, theme, notifications } = useSelector(state => state);
return <div>{user.name}</div>; // Only uses user but still re-renders when cart/theme/notifications change
};
// Must use reselect for optimization
const selectUserName = createSelector(
state => state.user,
user => user.name
);
React Signify - Automatically optimized:
// ✅ React Signify - Only re-renders when data actually needs
const sUser = signify({ name: 'John', age: 25 });
const sCart = signify([]);
const sTheme = signify('light');
function MyComponent() {
const user = sUser.use(); // Only re-renders when sUser changes
return <div>{user.name}</div>;
}
// sCart.set([...]) or sTheme.set('dark') does NOT make MyComponent re-render
3. TypeScript Support
Redux - Complex configuration:
// ❌ Redux - Manual types setup required
interface RootState {
counter: number;
user: User | null;
}
interface AppDispatch extends ThunkDispatch<RootState, any, AnyAction> {}
const useAppSelector: TypedUseSelectorHook<RootState> = useSelector;
const useAppDispatch = () => useDispatch<AppDispatch>();
// Must type every action
interface IncrementAction {
type: 'INCREMENT';
}
interface SetUserAction {
type: 'SET_USER';
payload: User;
}
type CounterAction = IncrementAction | SetUserAction;
React Signify - TypeScript automatic:
// ✅ React Signify - Fully automatic TypeScript
const sCounter = signify(0); // Auto infers type: number
const sUser = signify<User | null>(null); // Explicit type when needed
function MyComponent() {
const counter = sCounter.use(); // Type: number
const user = sUser.use(); // Type: User | null
// TypeScript will error if type is wrong
sCounter.set("string"); // ❌ Error: string cannot be assigned to number
}
4. Async Actions
Redux - Requires middleware:
// ❌ Redux - Needs redux-thunk or redux-saga
const fetchUser = (id) => async (dispatch) => {
dispatch({ type: 'FETCH_USER_START' });
try {
const user = await api.getUser(id);
dispatch({ type: 'FETCH_USER_SUCCESS', payload: user });
} catch (error) {
dispatch({ type: 'FETCH_USER_ERROR', payload: error.message });
}
};
React Signify - Natural:
// ✅ React Signify - Async naturally
const sUser = signify(null);
const sLoading = signify(false);
const fetchUser = async (id) => {
sLoading.set(true);
try {
const user = await api.getUser(id);
sUser.set(user);
} catch (error) {
console.error(error);
} finally {
sLoading.set(false);
}
};
React Signify vs Zustand
Overview Comparison
Criteria | React Signify | Zustand |
---|---|---|
API Style | Signal-based (reactive) | Store-based (imperative) |
Slicing | Built-in with .slice() | Manual implementation required |
Conditional Updates | Built-in | Manual implementation required |
Cross-tab Sync | Built-in | Plugin/middleware required |
Performance Wrappers | Wrap , HardWrap | Manual optimization required |
DevTools | Built-in | Configuration required |
Bundle Size | ~4KB | ~2.5KB |
Detailed Comparison
1. API Design Philosophy
Zustand - Store-based (Imperative):
// Zustand - Traditional store mindset
const useStore = create((set, get) => ({
count: 0,
user: null,
increment: () => set(state => ({ count: state.count + 1 })),
setUser: (user) => set({ user }),
// Must define methods inside store
}));
function MyComponent() {
const count = useStore(state => state.count);
const increment = useStore(state => state.increment);
return <button onClick={increment}>{count}</button>;
}
React Signify - Signal-based (Reactive):
// React Signify - Reactive mindset, more natural
const sCount = signify(0);
const sUser = signify(null);
// Actions can be anywhere, not tied to store
const increment = () => sCount.set(prev => {
prev.value += 1;
});
const setUser = (user) => sUser.set(user);
function MyComponent() {
const count = sCount.use(); // Simple, direct
return <button onClick={increment}>{count}</button>;
}
2. Slicing & Selective Subscriptions
Zustand - Manual implementation required:
// ❌ Zustand - Complex selectors for nested data
const useStore = create(() => ({
user: {
profile: { name: 'John', age: 25 },
preferences: { theme: 'light', language: 'en' }
}
}));
// Must write careful selectors to avoid unnecessary re-renders
function UserName() {
// Component will re-render when age, theme, language changes
const name = useStore(state => state.user.profile.name);
return <span>{name}</span>;
}
// Or must use shallow compare
import { shallow } from 'zustand/shallow';
function UserProfile() {
const profile = useStore(state => state.user.profile, shallow);
return <div>{profile.name} - {profile.age}</div>;
}
React Signify - Built-in slicing:
// ✅ React Signify - Automatic and optimized slicing
const sUser = signify({
profile: { name: 'John', age: 25 },
preferences: { theme: 'light', language: 'en' }
});
// Create slice that only tracks name
const ssUserName = sUser.slice(user => user.profile.name);
function UserName() {
const name = ssUserName.use(); // Only re-renders when name changes
return <span>{name}</span>;
}
// Changing age/theme/language does NOT make UserName re-render
sUser.set(prev => ({
...prev.value,
profile: { ...prev.value.profile, age: 26 }
})); // UserName does NOT re-render
3. Cross-tab Synchronization
Zustand - Requires middleware:
// ❌ Zustand - Needs additional middleware
import { subscribeWithSelector } from 'zustand/middleware';
import { persist } from 'zustand/middleware';
const useStore = create(
persist(
subscribeWithSelector((set) => ({
cart: [],
addToCart: (item) => set(state => ({
cart: [...state.cart, item]
})),
})),
{
name: 'cart-storage', // Storage key
// Need additional configuration for cross-tab sync
}
)
);
// Cross-tab sync is complex and not real-time
React Signify - Built-in sync:
// ✅ React Signify - Cross-tab sync built-in
const sCart = signify([], {
syncKey: 'shopping-cart' // Automatically syncs between tabs
});
// Add product in tab 1
sCart.set(prev => {
prev.value.push(newItem);
});
// Tab 2 automatically updates real-time! No additional work needed
4. Conditional Updates & Performance
Zustand - Manual implementation:
// ❌ Zustand - Must write conditional update logic manually
const useStore = create((set, get) => ({
score: 0,
updateScore: (newScore) => {
const currentScore = get().score;
// Must manually check condition
if (newScore > currentScore) {
set({ score: newScore });
}
},
}));
React Signify - Built-in conditional:
// ✅ React Signify - Built-in conditional updates
const sScore = signify(0);
// Only update when condition is met
sScore.conditionUpdating((prev, curr) => curr > prev);
sScore.set(5); // ✅ Update: 0 → 5
sScore.set(3); // ❌ No update because 3 < 5
sScore.set(10); // ✅ Update: 5 → 10
// Conditional rendering
sScore.conditionRendering(value => value % 10 === 0);
// Component only re-renders when score is 10, 20, 30, ...
React Signify vs Context API
Overview Comparison
Criteria | React Signify | Context API |
---|---|---|
Re-render scope | Surgical (only needed components) | Entire component tree |
Provider setup | Not required | Required |
Multiple contexts | Easy | Complex nested providers |
Performance | Automatically optimized | Requires memo/callback optimization |
Value memoization | Automatic | Manual required |
Detailed Comparison
1. Provider Hell vs No Provider
Context API - Provider Hell:
// ❌ Context API - Complex nested providers
function App() {
return (
<UserProvider>
<ThemeProvider>
<CartProvider>
<NotificationProvider>
<LocaleProvider>
<Component /> {/* Too many wrapper layers */}
</LocaleProvider>
</NotificationProvider>
</CartProvider>
</ThemeProvider>
</UserProvider>
);
}
React Signify - No Provider needed:
// ✅ React Signify - Clean, no providers needed
const sUser = signify(null);
const sTheme = signify('light');
const sCart = signify([]);
const sNotifications = signify([]);
const sLocale = signify('en');
function App() {
return <Component />; // Clean, no wrappers
}
2. Re-render Performance
Context API - Entire tree re-renders:
// ❌ Context API - All children re-render
const UserContext = createContext();
function UserProvider({ children }) {
const [user, setUser] = useState({ name: 'John', age: 25 });
// When user changes, ALL children will re-render
return (
<UserContext.Provider value={{ user, setUser }}>
{children}
</UserContext.Provider>
);
}
function App() {
return (
<UserProvider>
<Header /> {/* Re-renders when user changes */}
<Sidebar /> {/* Re-renders when user changes */}
<Content /> {/* Re-renders when user changes */}
<Footer /> {/* Re-renders when user changes */}
</UserProvider>
);
}
React Signify - Surgical re-renders:
// ✅ React Signify - Only components that use it re-render
const sUser = signify({ name: 'John', age: 25 });
function Header() {
const user = sUser.use(); // Re-renders when user changes
return <div>Welcome {user.name}</div>;
}
function Sidebar() {
// Does NOT re-render when user changes
return <div>Static sidebar</div>;
}
function Content() {
const user = sUser.use(); // Re-renders when user changes
return <div>Content for {user.name}</div>;
}
function Footer() {
// Does NOT re-render when user changes
return <div>Static footer</div>;
}
