+# Turbo Streams
+
+ViewComponents can be used with [Turbo Streams](https://turbo.hotwired.dev/handbook/streams) to broadcast updates over WebSockets.
+
+## Rendering in controllers
+
+In a controller action, render a component inside a Turbo Stream response using `render_to_string` or `view_context.render`:
+
+```ruby
+class MessagesController < ApplicationController
+  def create
+    @message = Message.create!(message_params)
+
+    Turbo::StreamsChannel.broadcast_append_to(
+      "messages",
+      target: "messages",
+      html: render_to_string(MessageComponent.new(message: @message))
+    )
+  end
+end
+```
+
+## Broadcasting later with ActiveJob
+
+To broadcast asynchronously via ActiveJob (using `broadcast_action_later_to`), components must be serializable so they can be passed to the background job.
+
+### Setup
+
+Include `ViewComponent::Serializable` in the component and use `.serializable` instead of `.new` when broadcasting:
+
+```ruby
+class MessageComponent < ViewComponent::Base
+  include ViewComponent::Serializable
+
+  def initialize(message:)
+    @message = message
+  end
+
+  erb_template <<~ERB
+    <div id="<%= dom_id(@message) %>">
+      <%= @message.body %>
+    </div>
+  ERB
+end
+```
+
+### Broadcasting
+
+Use `.serializable` to create a component instance that can be serialized by ActiveJob:
+
+```ruby
+class Message < ApplicationRecord
+  after_create_commit :broadcast_append
+
+  private
+
+  def broadcast_append
+    Turbo::StreamsChannel.broadcast_action_later_to(
+      "messages",
+      action: :append,
+      target: "messages",
+      renderable: MessageComponent.serializable(message: self),
+      layout: false
+    )
+  end
+end
+```
+
+The component is serialized when the job is enqueued and deserialized when the job runs. The job renders the component via `ApplicationController.render` and broadcasts the resulting HTML over ActionCable.
+
+### How it works
+
+- `.serializable(**kwargs)` creates a normal component instance and stores the keyword arguments for later serialization.
+- `ViewComponent::SerializableSerializer` (an ActiveJob serializer) handles converting the component to and from a JSON-safe format. It's automatically registered when ActiveJob is loaded.
+- ActiveRecord objects passed as keyword arguments are serialized via GlobalID, just like any other ActiveJob argument.
+
+### Limitations
+
+- Only keyword arguments passed to `.serializable` are serialized. Slots, `with_content`, and other state set after initialization are not included.
+- Components must be instantiated with `.serializable` instead of `.new` for serialization to work. Instances created with `.new` are not serializable.
+- The component class must be `safe_constantize`-able at deserialization time (i.e., it must be autoloadable).
