deephaven-example-app

This is an example Deephaven application built using the deephaven-server PyPi package.

It demonstrates connecting to a real-time data source, performing simple operations on that data, and presenting the data to the user in the web UI.

The Coinbase websocket exchange feed was chosen as a data source for this example as it's simple to get up and running. It is not meant to have exhaustive coverage.

Requirements

• Python >= 3.7
