const SakshWallet = require('saksh-easy-wallet');

// Example usage
(async () => {
    try {
        const userEmail = '[email protected]';

        // Connect to the database
        await mongoose.connect('mongodb://localhost:27017/saksh2323Cart', {
            useNewUrlParser: true,
            useUnifiedTopology: true,
        });
        console.log('Database connected');

        const wallet = new SakshWallet();

        // Set admin email (optional)
        wallet.setAdmin('[email protected]');

        // Credit an amount to the user's wallet
        console.log(await wallet.sakshCredit(userEmail, 500, 'USD', 'ref123', 'Salary payment')); // Credited 500 USD. New balance is 500

        // Debit an amount from the user's wallet
        console.log(await wallet.sakshDebit(userEmail, 200, 'USD', 'ref124', 'Grocery shopping', 5)); // Debited 200 USD. New balance is 295

        // Get balance for a user
        const balance = await wallet.sakshGetBalance(userEmail, 'USD');
        console.log('User Balance:', balance); // User Balance: { email: '[email protected]', currency: 'USD', balance: 295 }

        // Get balance summary for a user
        const balanceSummary = await wallet.sakshGetBalanceSummary(userEmail);
        console.log('Balance Summary:', balanceSummary); // Balance Summary: { email: '[email protected]', balance: { 'USD': 295 } }

        // Close the MongoDB connection
        await mongoose.connection.close();
    } catch (error) {
        console.error('Error:', error);
    }
})();
