# Drop-in replacement for Mozo::Broadcaster::Faye that uses
|
|
# Rails' built-in ActionCable instead of an external Faye process.
|
|
#
|
|
# Benefits over Faye:
|
|
# - Async by default (ActionCable.server.broadcast is non-blocking)
|
|
# - No extra gem / process / port to manage
|
|
# - Integrated with Rails authentication (cookies, sessions)
|
|
# - WebSocket native (no long-polling fallback needed with modern browsers)
|
|
#
|
|
# Channel naming: accepts both Faye format and underscore format:
|
|
# /user/123 or /user_123 → user_123
|
|
# /supplier/456 or /supplier_456 → supplier_456
|
|
#
|
|
# To use:
|
|
# Set Mozo.broadcaster = Mozo::Broadcaster::ActionCable.new
|
|
# in config/initializers/mozo_settings.rb
|
|
#
|
