Action Cable Overview
Connections form the foundation of the client-server relationship. A single Action Cable server can handle multiple connection instances. It has one connection instance per WebSocket connection. A single user may have multiple WebSockets open to your application if they use multiple browser tabs or devices.
Each consumer can in turn subscribe to multiple channels. Each channel encapsulates a logical unit of work, similar to what a controller does in a regular MVC setup. For example, you could have a ChatChannel and an AppearancesChannel, and a consumer could be subscribed to either or to both of these channels. At the very least, a consumer should be subscribed to one channel.
When the consumer is subscribed to a channel, they act as a subscriber. The connection between the subscriber and the channel is, surprise-surprise, called a subscription. A consumer can act as a subscriber to a given channel any number of times. For example, a consumer could subscribe to multiple chat rooms at the same time. (And remember that a physical user may have multiple consumers, one per tab/device open to your connection).
Pub/Sub, vvdi mb cable or Publish-Subscribe, refers to a message queue paradigm whereby senders of information (publishers), send data to an abstract class of recipients (subscribers), without specifying individual recipients. Action Cable uses this approach to communicate between the server and many clients.
A broadcasting is a pub/sub link where anything transmitted by the broadcaster is sent directly to the channel subscribers who are streaming that named broadcasting. Each channel can be streaming zero or more broadcastings.
For every WebSocket accepted by the server, a connection object is instantiated. This object becomes the parent of all the channel subscriptions that are created from there on. The connection itself does not deal with any specific application logic beyond authentication and authorization. The client of a WebSocket connection is called the connection consumer. An individual user will create one consumer-connection pair per browser tab, window, or device they have open.
By default, vvdi mb cable unhandled exceptions are caught and logged to Rails’ logger. If you would like to globally intercept these exceptions and report them to an external bug tracking service
A channel encapsulates a logical unit of work, similar to what a controller does in a regular MVC setup. By default, Rails creates a parent ApplicationCable::Channel class (which extends ActionCable::Channel::Base) for encapsulating shared logic between your channels.
Consumers subscribe to channels, acting as subscribers. Their connection is called a subscription. Produced messages are then routed to these channel subscriptions based on an identifier sent by the channel consumer.
This will ready a consumer that’ll connect against /cable on your server by default. The connection won’t be established until you’ve also specified at least one subscription you’re interested in having.
The consumer can optionally take an argument that specifies the URL to connect to. This can be a string, or a function that returns a string that will be called when the WebSocket is opened.
While this creates the subscription, the functionality needed to respond to received data will be described later on.
A consumer can act as a subscriber to a given channel any number of times
Streams provide the mechanism by which channels route published content (broadcasts) to their subscribers. For example, the following code uses stream_from to subscribe to the broadcasting named chat_Best Room when the value of the :room parameter is Best Room
A broadcasting is a pub/sub link where anything transmitted by a publisher is routed directly to the channel subscribers who are streaming that named broadcasting. Each channel can be streaming zero or more broadcastings.
Broadcastings are purely an online queue and time-dependent. If a consumer is not streaming (subscribed to a given channel), they’ll not get the broadcast should they connect later.
When a consumer is subscribed to a channel, they act as a subscriber. This connection is called a subscription. Incoming messages are then routed to these channel subscriptions based on an identifier sent by the cable consumer.
