Getting Started

Create a store with initial state:

You can think of a store as your app state. You can define multiple keys/values, each key will create separated subscription (more explained here). If you want to persist the value - you can simply wrap it in Synchronizer

import { createStore } from 'stan-js'
import { storage } from 'stan-js/storage'

export const { useStore } = createStore({
    count: 0,
    get doubleCount() {
        return this.count * 2
    }, 
    user: storage(''),
    selectedLanguage: 'en-US',
    unreadNotifications: [] as Array<Notification>
})

Use the returned hook in your React component:

import { useStore } from './store'

const App = () => {
    const { count, user, setCount } = useStore()

    return (



            <h1>Hello {user}!</h1>


Count: {count}


            <button onClick={() => setCount(prev => prev + 1)}>Increment</button>
            <button onClick={() => setCount(prev => prev - 1)}>Decrement</button>



    )
}
