Reporting Unknown Actions with Analytics

// Middleware function to catch unknown actions
const unknownActionReporter = store => next => action => {
    // Let the action pass through
    next(action);

    // Verify if the action type is unknown
    if (action.type === 'UNKNOWN_ACTION') {
        // Prepare the data to be sent to analytics
        const analyticsData = {
            timestamp: new Date().toISOString(),
            action: action
        };

        // Report the unknown action to the analytics server
        fetch('https://your-analytics-endpoint.com/report', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },
            body: JSON.stringify(analyticsData)
        })
        .then(response => response.json())
        .then(data => console.log('Unknown action reported:', data))
        .catch(error => console.error('Error reporting unknown action:', error));
    }
};

// Usage in a Redux store setup
// import { createStore, applyMiddleware } from 'redux';
// const store = createStore(
//     rootReducer,
//     applyMiddleware(unknownActionReporter)
// );
