Account projections example

A simple and elegant view of getting current account details and associated transactions.

Installation

Open your node terminal.

# Clone project from GitHub
git clone \
   https://github.com/balamuralisrinivasan/acct-projections

# Install dependencies
npm install --save

# Fire-up the engine
npm start

You are good to go; access the console is here and the API is published under the URI http://localhost:8080/graphql.

Seed Data

The project already has the seed data under ./test/*.js for:

  • Accounts (test-data/accounts.json)
  • Transactions (test-data/transactions.json)

You can regenerate this data - althrough not required - using the command:

node seed/seed_loader.js

The seed_loader.js uses the fantastic casual framework to generate awesome test data.

Advanced stuff

Generate lots and lots of data with the MongoDB backend; assure your backend is started, for example:

mongod --dbpath=./mongodb-data

Now, generate using the seed_loader tool the desired dataset:

node seed/seed_loader.js --dataStorageType=mongodb \
   --mongodbUrl=mongodb://localhost:27017/acctprojection \
   --nrOfAccounts=1000 \
   --nrOfTransPerAccount=10000 \
   --transHistoryStartYear=2008

Usage

Explore and discover by playing with queries. A sample query is here below. A basic query to get only the account details.

query myAccount {
  currentAccount(account: {iban: "IE89CITI73317996533808"}) {
    name
    iban
    availableBalance
    mailingAddress {
      city
      postalCode
      address
      countryCode
    }
  }
    
}

Retreive nested transactions posted using the same account. The transactions can be filtered for transactions posted on or later than startDate as given below.

query myAccount {
  currentAccount(account: {iban: "IE89CITI73317996533808"}) {
    name
    iban
    availableBalance
    mailingAddress {
      city
      postalCode
      address
      countryCode
    }
    transactions(dateRange: {
      startDate: "2016-10-01"
    }) {
      valueDate
      acctRef
      acctBalance
      partyInf
      {
        account
        bankReferenceNo
        instrumentID
        billingAddress
        {
          address
        }
        
      }
      amount
     
    }

  }
    
}

Now add an end date and narrow down the filter.

query myAccount {
  currentAccount(account: {iban: "IE89CITI73317996533808"}) {
    name
    iban
    availableBalance
    mailingAddress {
      city
      postalCode
      address
      countryCode
    }
    transactions(dateRange: {
      startDate: "2016-10-01",
      endDate: "2016-12-01"
    }) {
      valueDate
      acctRef
      acctBalance
      partyInf
      {
        account
        bankReferenceNo
        instrumentID
        billingAddress
        {
          address
        }
        
      }
      amount
     
    }

  }
    
}

Functional test automation

A sample scenario has been automated using jest:

Run your QA server which will just run the API end point and not graphiQL.

npm run-script qaserver

Run the tests which will iterate through all js files in tests folder and run as a single Test Suite.

npm test
