🔧 Integration Guide

Step 1: Install the Package

Choose your preferred package manager:

# NPM
npm install @pratik.vekariya1/react-native-sdk

# Yarn
yarn add @pratik.vekariya1/react-native-sdk

# PNPM
pnpm add @pratik.vekariya1/react-native-sdk

Step 2: Platform Setup

iOS Setup

1. Navigate to iOS directory and install pods:

cd ios && pod install && cd ..

2. For iOS 9+ support, add this to your ios/Podfile:

platform :ios, '11.0'

3. If you encounter build issues, clean and rebuild:

npx react-native clean
cd ios && xcodebuild clean && cd ..

Android Setup

1. Ensure your android/build.gradle has minimum SDK version:

buildscript {
    ext {
        minSdkVersion = 21
        compileSdkVersion = 33
        targetSdkVersion = 33
    }
}

2. Add to android/app/build.gradle if needed:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Step 3: Initialize the SDK

Option A: Initialize in App.js/App.tsx (Recommended)

import React, { useEffect } from 'react';
import { initializeSDK } from '@pratik.vekariya1/react-native-sdk';

const App = () => {
  useEffect(() => {
    // Initialize SDK when app starts
    initializeSDK({
      apiKey: 'your-api-key-here',
      environment: 'production', // or 'development'
      debugMode: __DEV__, // Enable debug in development
    });
  }, []);

  return (
    // Your app content
  );
};

export default App;

Option B: Initialize in index.js (Early initialization)

import { AppRegistry } from 'react-native';
import { initializeSDK } from '@pratik.vekariya1/react-native-sdk';
import App from './App';
import { name as appName } from './app.json';

// Initialize SDK before app registration
initializeSDK({
  apiKey: 'your-api-key-here',
  environment: 'production',
});

AppRegistry.registerComponent(appName, () => App);

Step 4: Basic Implementation

Using Hooks (Recommended)

import React, { useState } from 'react';
import { View, Button, Text, Alert } from 'react-native';
import { useSDK } from '@pratik.vekariya1/react-native-sdk';

const MyComponent = () => {
  const { isReady, error, performAction } = useSDK();
  const [result, setResult] = useState(null);

  const handleAction = async () => {
    try {
      const data = await performAction('some-parameter');
      setResult(data);
      Alert.alert('Success', 'Action completed successfully');
    } catch (err) {
      Alert.alert('Error', err.message);
    }
  };

  if (!isReady) {
    return <Text>SDK Loading...</Text>;
  }

  if (error) {
    return <Text>SDK Error: {error.message}</Text>;
  }

  return (
    <View>
      <Button title="Perform SDK Action" onPress={handleAction} />
      {result && <Text>Result: {JSON.stringify(result)}</Text>}
    </View>
  );
};

export default MyComponent;

Using Components

import React from 'react';
import { View, StyleSheet } from 'react-native';
import { SDKComponent } from '@pratik.vekariya1/react-native-sdk';

const MyScreen = () => {
  const handleSuccess = (data) => {
    console.log('SDK Success:', data);
    // Handle successful operation
  };

  const handleError = (error) => {
    console.error('SDK Error:', error);
    // Handle error
  };

  return (
    <View style={styles.container}>
      <SDKComponent
        onSuccess={handleSuccess}
        onError={handleError}
        style={styles.sdkComponent}
        // Additional props based on your SDK
        config={{
          theme: 'light',
          customOption: true
        }}
      />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 16,
  },
  sdkComponent: {
    height: 200,
    borderRadius: 8,
  },
});

export default MyScreen;

Step 5: Environment Configuration

Development Environment

// config/development.js
export const SDK_CONFIG = {
  apiKey: 'dev-api-key',
  environment: 'development',
  debugMode: true,
  baseURL: 'https://dev-api.yourservice.com',
  timeout: 30000,
};

Production Environment

// config/production.js
export const SDK_CONFIG = {
  apiKey: 'prod-api-key',
  environment: 'production',
  debugMode: false,
  baseURL: 'https://api.yourservice.com',
  timeout: 10000,
};

Using Environment Config

import { SDK_CONFIG } from './config/development'; // or production
import { initializeSDK } from '@pratik.vekariya1/react-native-sdk';

initializeSDK(SDK_CONFIG);

🔄 Migration Guide

From Version 0.x to 1.x

// OLD (v0.x)
import SDK from '@pratik.vekariya1/react-native-sdk';
SDK.init('your-api-key');

// NEW (v1.x)
import { initializeSDK } from '@pratik.vekariya1/react-native-sdk';
initializeSDK({
  apiKey: 'your-api-key',
  environment: 'production'
});

Breaking Changes in v1.x

1. Initialization method changed - Use initializeSDK() instead of SDK.init()
2. Import structure updated - Named imports instead of default
3. Configuration object required - API key alone is not sufficient

  networkLogging: true
});

📋 Integration Best Practices

1. Error Boundary Implementation

import React from 'react';
import { Text, View } from 'react-native';

class SDKErrorBoundary extends React.Component {
  constructor(props) {
    super(props);
    this.state = { hasError: false, error: null };
  }

  static getDerivedStateFromError(error) {
    return { hasError: true, error };
  }

  componentDidCatch(error, errorInfo) {
    console.log('SDK Error Boundary:', error, errorInfo);
    // Report to error tracking service
  }

  render() {
    if (this.state.hasError) {
      return (
        <View style={{ padding: 20, alignItems: 'center' }}>
          <Text>Something went wrong with SDK</Text>
        </View>
      );
    }

    return this.props.children;
  }
}

// Wrap your SDK components
<SDKErrorBoundary>
  <YourSDKComponent />
</SDKErrorBoundary>

2. Loading State Management

import React, { useState, useEffect } from 'react';
import { View, ActivityIndicator } from 'react-native';
import { initializeSDK, isSDKReady } from '@pratik.vekariya1/react-native-sdk';

const App = () => {
  const [sdkReady, setSDKReady] = useState(false);

  useEffect(() => {
    const initSDK = async () => {
      try {
        await initializeSDK({
          apiKey: 'your-key',
          environment: 'production'
        });
        setSDKReady(isSDKReady());
      } catch (error) {
        console.error('SDK initialization failed:', error);
      }
    };

    initSDK();
  }, []);

  if (!sdkReady) {
    return (
      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
        <ActivityIndicator size="large" />
      </View>
    );
  }

  return (
    // Your app content
  );
};

3. Secure API Key Storage

// Never hardcode API keys in production
// Use react-native-config or similar
import Config from 'react-native-config';

initializeSDK({
  apiKey: Config.SDK_API_KEY, // Stored in .env file
  environment: Config.ENVIRONMENT
});

🔍 Troubleshooting

Common Issues

Issue: Module not found

Solution: Make sure to run pod install for iOS and clean your build cache:

# For iOS
cd ios && pod install

# Clean cache
npx react-native start --reset-cache

Issue: Build errors on Android

Solution: Ensure your android/build.gradle has the minimum SDK version:

minSdkVersion 21

Debug Mode

Enable debug mode to get detailed logs:

configure({ debugMode: true });
