Singer is an open-source standard for writing scripts
that move data.
It describes how data extraction scripts—called “Taps”
—and data loading scripts—called “Targets”—
should communicate, allowing them to be used in any combination
to move data from any source to any destination. Send data between databases, web APIs, files,
queues, and just about anything else you can think of.

For example, these two simple commands pull currency exchange rate data from
Fixer.io into a CSV file:
› pip install target-csv tap-fixerio
› tap-fixerio | target-csv
INFO Replicating the latest exchange rate data from fixer.io
INFO Tap exiting normally
› cat exchange_rate.csv
