Installation

npm install usereactstate
# or
yarn add usereactstate

Quick Start

import { StateProvider, useStateValue } from 'usereactstate';

function App() {
  return (
    <StateProvider initialState={{ user: { name: 'John' } }}>
      <UserProfile />
    </StateProvider>
  );
}

function UserProfile() {
  const [user, setUser] = useStateValue('user');
  
  return (
    <div>
      <h1>Welcome, {user.name}!</h1>
      <button onClick={() => setUser({ ...user, name: 'Jane' })}>
        Change Name
      </button>
    </div>
  );
}

Core Concepts

State Provider

The StateProvider component is the root of your state management system:

<StateProvider 
  initialState={{ /* your initial state */ }}
  debug={true} // Enable debugging
>
  {/* Your app components */}
</StateProvider>

State Management Hooks

useStateValue

Get and set state values with type safety:

const [value, setValue] = useStateValue<string>('path.to.value');

useStateWatch

Watch state changes without the ability to modify:

const value = useStateWatch<string>('path.to.value');

useStore

Access the entire store context:

const { state, setState, mergeState } = useStore();

useEntireStore

Get the complete state object:

const state = useEntireStore();

Debugging

Enable the debug mode and use the StateDebugger component:

import { StateProvider, StateDebugger } from 'usereactstate';

function App() {
  return (
    <StateProvider debug={true}>
      <StateDebugger />
      {/* Your app components */}
    </StateProvider>
  );
}

Data Fetching

The library includes a query client for data fetching:

import { queryClient } from 'usereactstate';

// Use in your components
const data = await queryClient.get('/api/data');

Advanced Usage

State Paths

State paths can be specified as strings or arrays:

// Both are equivalent
const [value] = useStateValue('user.profile.name');
const [value] = useStateValue(['user', 'profile', 'name']);

Performance Optimization

The library is optimized for performance with:

• Path-based updates
• Memoized selectors
• Batched updates
• Minimal re-renders

Type Safety

Full TypeScript support with generics:

interface User {
  name: string;
  age: number;
}

const [user, setUser] = useStateValue<User>('user');
