This is a simple app demonstrating 1) parsing a binary log representing bank transactions into JSON and 2) running sample queries against the transformed result.

• Node (This app has been tested against v6.11 & v8.10.)

The following will install necessary dependencies:

npm install

The following will parse ./data/txnlog.dat and print a report.

npm run parse

If you'd like to specify a custom binary log file or write the output to disk, parse.js has the following options:

node ./parse [--infile INFILE] [--outfile OUTFILE]

• INFILE: Local path to binary file to parse. Default ./data/txnlog.dat
• OUTFILE: Local path to write parsed document. Default /dev/null

Standard JS linting and a modest test suite can be run as follows:

npm test
