API Reference

tap()

tap: invoke a side effect on each DATA (function form) or on data/error/complete (observer form); values pass through unchanged. The observer form reads source terminals (completeWhenDepsComplete:false + errorWhenDepsError:false + terminalAsRealInput:true) so it can call error/complete then forward the terminal; the function form lets the substrate auto-cascade terminals.
