Co-authored-by: Aurelia <aurelia@serenitylabs.cloud>

Procfile

-web: if [ "$RUN_STREAMING" != "true" ]; then BIND=0.0.0.0 bundle exec puma -C config/puma.rb; else BIND=0.0.0.0 node ./streaming; fi
+web: bin/heroku-web
 worker: bundle exec sidekiq
 
 # For the streaming API, you need a separate app that shares Postgres and Redis:

bin/heroku-web

+#!/bin/bash
+if [ "$RUN_STREAMING" != "true" ]; then BIND=0.0.0.0 bundle exec puma -C config/puma.rb; else BIND=0.0.0.0 node ./streaming; fi
