Print | Unofficial JDA (Javascript Dataflow Architecture) Wiki

This blueprint can be put between any other blueprint, like a T-wiring, and just dumps all messages on its designed element,a nd passes them along. Good for debugging hard-to-grok blueprints and/or wirings.

## Input Terminals + in: (expected message type: anything) ## Output Terminals + out: (Passing forward the input message on 'in') ## Properties + none ## Demos that use it ## How does it work This blueprint copies the data coming on the 'in' input terminal to the output terminal 'out' and simultaneously (OK, almost) to innerHTML of its DOM node --------
