Conduit is an open source, example Phoenix 1.3 web application implementing the CQRS/ES pattern in Elixir. It was built to demonstrate the implementation of Commanded in an Elixir application for the Building Conduit book.
Commanded is currently limited to running on a single node. Support for running on a cluster of nodes (#39) is under active development.
