Overview

The streams channel delivers all the turbo-stream actions created (primarily) through Turbo::Broadcastable. A subscription to this channel is made for each individual stream that one wishes to listen for updates to. The subscription relies on being passed a signed_stream_name parameter generated by turning a set of streamables into signed stream name using Turbo::Streams::StreamName#signed_stream_name. This is automatically done using the view helper Turbo::StreamsHelper#turbo_stream_from(*streamables). If the signed stream name cannot be verified, the subscription is rejected.
