Nightingale.space - Elm and Crowd-Sourced Music Making
summary
Uses Elm plus Elixir’s Phoenix and Twitter to turn tweets into live music, broadcasting tweets via Phoenix channels, parsing a compact 140‑char DSL with regexes and Elm Combine parsers to extract note, accidental, length and octave and also start/end indices for highlighting, serializing to JS-friendly objects and sending them out through ports to Tone.js to schedule sound. Backend runs a reader/listener queue, parsing is lenient (ignores errors), the live demo plays audience tweets successfully though a few parser edge‑case bugs appear, and the app avoids runtime exceptions.
