React Native Global Store

Overview

React Native Global Store is a lightweight and efficient global state management solution for React Native with built-in AsyncStorage persistence. It provides an easy-to-use API for managing state globally without the complexities of Redux or Context APIs.

Features

• No store configuration required.
• No reducers or actions needed.
• Pure JavaScript (TypeScript supported).
• No middleware or dispatch complications.
• Simple API similar to React's useState.
• Easy connection with components using connect.
• Functional component support with useGlobalStore.
• Inspired by Redux but optimized for simplicity and performance.
• Automatically persists selected state keys using AsyncStorage.

Installation

• Install React Native Async Storage (required) if not already installed.
• Install React Native Global Store:

npm install react-native-global-store

- OR -

yarn add react-native-global-store

No linking or Pods required. Ready to use!

Usage

GlobalStoreProvider

Wrap your app with GlobalStoreProvider to provide global state management.

Props

Prop	Type	Default	Description
initialState	object	{}	Initial state for the store.
persistedKeys	string[]	[]	Keys to persist in AsyncStorage.
loadingUI	JSX.Element	<View />	UI to display while loading persisted state.
storageKey	string	"GlobalStoreProvider"	Unique key for AsyncStorage.

Example

import React from "react";
import { GlobalStoreProvider } from "react-native-global-store";
import App from "./App";

const myInitialState = { theme: "light" };

const Root = () => (
  <GlobalStoreProvider 
    initialState={myInitialState} 
    loadingUI={<LoadingComponent />} 
    persistedKeys={["theme"]}
  >
    <App />
  </GlobalStoreProvider>
);

export default Root;

useGlobalStore

A hook for accessing and updating the global state in functional components.

Example

import React from "react";
import { useGlobalStore } from "react-native-global-store";
import { Text, Button } from "react-native";

const MyComponent = () => {
  const [globalState, setGlobalState] = useGlobalStore();

  return (
    <>
      <Text>Current Theme: {globalState.theme}</Text>
      <Button title="Toggle Theme" onPress={() => 
        setGlobalState({ theme: globalState.theme === "light" ? "dark" : "light" })
      } />
    </>
  );
};

export default MyComponent;

connect

A higher-order component (HOC) for connecting class components to the global store.

Example

import React, { Component } from "react";
import { View, Text, Button } from "react-native";
import { connect } from "react-native-global-store";

class SettingsScreen extends Component {
  render() {
    const { theme, setGlobalState } = this.props;
    return (
      <View>
        <Text>Current Theme: {theme}</Text>
        <Button title="Toggle Theme" onPress={() => 
          setGlobalState({ theme: theme === "light" ? "dark" : "light" })
        } />
      </View>
    );
  }
}

export default connect(SettingsScreen);
