instance method turbo_stream

Returns a new Turbo::Streams::TagBuilder object that accepts stream actions and renders them as the template tags needed to send across the wire. This object is automatically yielded to turbo_stream.erb templates.

When responding to HTTP requests, controllers can declare turbo_stream format response templates in that same style as html and json response formats. For example, consider a MessagesController that responds to both text/html and text/vnd.turbo-stream.html requests along with a .turbo_stream.erb action template:

def create
  @message = Message.create!(params.require(:message).permit(:content))
  respond_to do |format|
    format.turbo_stream
    format.html { redirect_to messages_url }
  end
end

<%# app/views/messages/create.turbo_stream.erb %>
<%= turbo_stream.append "messages", @message %>

<%= turbo_stream.replace "new_message" do %>
  <%= render partial: "new_message", locals: { room: @room } %>
<% end %>

When a app/views/messages/create.turbo_stream.erb template exists, the ‘MessagesController#create` will respond to text/vnd.turbo-stream.html requests by rendering the messages/create.turbo_stream.erb view template and transmitting the response
