@keithj/react-native-offline-sync v1.0.2

react-native-offline-sync

A lightweight React Native library to queue API requests when offline and automatically sync them when the device is back online.

🚀 Features

• 📡 Detects network status using @react-native-community/netinfo
• 📦 Queues failed or offline API requests
• 🔁 Automatically retries requests when online
• 🔄 Retry logic with max retry limit
• 🧠 Real-time queue size tracking
• 🧪 Hook-based API — no Redux required!

📦 Installation

npm install @keithj/react-native-offline-sync

Or with Yarn:

yarn add @keithj/react-native-offline-sync

You also need to install these peer dependencies:

yarn add @react-native-async-storage/async-storage @react-native-community/netinfo axios

🧠 Usage

import React from 'react';
import { View, Text, Button } from 'react-native';
import { useOfflineSync } from '@keithj/react-native-offline-sync';

export default function App() {
  const { isOnline, enqueueRequest, queueLength } = useOfflineSync();

  const handleSend = () => {
    enqueueRequest({
      request: {
        url: 'https://jsonplaceholder.typicode.com/posts',
        method: 'POST',
        data: {
          title: 'Offline Test',
          body: 'This request will be queued if offline.',
        },
      },
      options: {
        maxRetries: 5,
        preventDuplicate: true, // Optional: avoid enqueueing the same request again
      },
    });
  };

  return (
    <View>
      <Text>Network: {isOnline ? 'Online ✅' : 'Offline ❌'}</Text>
      <Text>Queue Length: {queueLength}</Text>
      <Button title="Send Request" onPress={handleSend} />
    </View>
  );
}

🔁 By default, the library will retry each request up to 3 times.
You can override this by passing maxRetries in the options object.

📌 Roadmap

• Retry with max attempts
• Queue length tracking
• Pause/resume queue
• Exponential backoff strategy
• Devtools panel (debug view)
• Configurable storage adapter
