Send logs from any React Native app, React/Vue web application, Node.js backend, Python service, or microservice in seconds.

1. React Native / Mobile Integration (Drop-in)

Import and use in any React Native / Expo application:

import { RemoteLogger } from './utils/RemoteLogger';

// 1. Initialize once in App.js
RemoteLogger.init({
    appId: 'my-mobile-app',
    appName: 'My Mobile App',
    hubUrl: 'http://YOUR_SERVER_IP:3000'
});

// 2. Track any function action
RemoteLogger.action('onUserLogin', 'User completed authentication', { userId: '123' });

// 3. Log errors anywhere
RemoteLogger.error('Payment failed', err, { amount: 49.99 });

2. Node.js / Express Middleware

Send logs directly via HTTP from another Node backend:

async function sendHubLog(level, functionName, message, data = null, error = null) {
    try {
        await fetch('http://YOUR_SERVER_IP:3000/api/logs/ingest', {
            method: 'POST',
            headers: { 'Content-Type': 'application/json' },
            body: JSON.stringify({
                appId: 'billing-service',
                appName: 'Billing Service',
                level,
                component: 'Billing:Stripe',
                functionName,
                message,
                data,
                error: error ? { message: error.message, stack: error.stack } : null
            })
        });
    } catch (e) {
        // Fallback
    }
}

3. cURL / REST API Endpoint

Send test or automated logs from shell scripts or CI/CD pipelines:

curl -X POST http://localhost:3000/api/logs/ingest \
  -H "Content-Type: application/json" \
  -d '{
    "appId": "custom-service",
    "appName": "Custom Service",
    "level": "INFO",
    "component": "Worker",
    "functionName": "processTask",
    "message": "Task processed successfully",
    "data": { "taskId": "T-9921", "durationMs": 45 }
  }'
