Boom (npm package) is used for error handling.

For in-memory implementation , transaction array is defined in at /models/index.js below format

transaction array = [{"type":"debit","amount":121,"parent_id":46564}];

/web/api/transaction/create

After basic sanitization check below function is called transactionList.addTxn(txnObj) defined at /models/index

This function will check whether transaction exits with same transaction id , if yes then throws error otherwise adds record to transaction list array
/web/api/transaction/get

Based on request url , this is handling get requests After checking url , 3 request types are defined in logic based on url inputs
```
 * transaction
 * types
 * sum
```
transaction request type - transactionList().getTxnById(transactionId) is called which is defined at /models/index

It will find transaction detail based on transaction_id as input response is returned if valid transaction is found.

types request type - transactionList().getTxnByType(type) is called which is defined at /models/index It will filter and return transactions id in array with have same type - debit/credit

sum request type - transactionList().getSumByParentId(transactionId) is called which is defined at /models/index

It will find parent_id based on transaction_id as input. After finding parent_id , it will return all the transaction linked to parent_id.

Sum of these filtered transaction is calculated using Array.reduce() and response is returned
