Red Erik is the test pattern page for testing Erlang-RED: visual low-code flow based programming for Erlang inspired by NodeRED.
Red Erik consists of a colletion of flows that describe/define/code how this website works. The entire content of this sites is stored flow files. In a way, that makes Red Erik a static website defined using flow based programming being executed on the BEAM.
Thanks to @mwmiller, Erlang-RED is also hosted at fly.io and can be tried out there.
This site is hosted at heroku and has no flow editor frontend.
Erlang-RED consists of a flow editor to create flows and a compute engine to execute flows. It is possible to just run the execute engine with a collection of interlinked flows. As is the case here.
