Loopback async/await transaction example

transaction.js

const Transaction = require('loopback-datasource-juggler');

const update = async (ids, delta) => {
  const result = [];
  const tx = await models.MyModel.beginTransaction({ isolationLevel: Transaction.READ_COMMITTED });
  try {
    for (const id of ids) {
      const entity = await updateById(id, delta, { transaction: tx });
      result.push(entity);
    }
    await tx.commit();
  } catch (e) {
    await tx.rollback();
    throw e;
  }
  return result;
};

Thanks! This really helped me
