const mongoose = require('mongoose');
const { Schema } = mongoose;

// Define schema
const userSchema = new Schema({
  name: String,
  email: String,
});

// Define models
const User = mongoose.model('User', userSchema);

async function performTransaction() {
  const session = await mongoose.startSession();
  session.startTransaction();
  
  try {
    // Perform operations within the transaction
    await User.create([{ name: 'John', email: 'john@example.com' }], { session });
    await User.create([{ name: 'Jane', email: 'jane@example.com' }], { session });

    // Commit the transaction
    await session.commitTransaction();
  } catch (error) {
    // Abort transaction if an error occurs
    await session.abortTransaction();
    throw error;
  } finally {
    // End the session
    session.endSession();
  }
}

// Usage
mongoose.connect('mongodb://localhost:27017/test', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to MongoDB');
    return performTransaction();
  })
