multiple turbo streams

1_turbo_stream_array_options.md

There are two ways to render multiple turbo streams:

1. via the controller rendering an array of streams
2. via a view file that contains multiple stream templates

The other two files on this gist demonstrate both methods.

DHH considers the first one bad.

I kinda like the first one because I think it makes it a little more obvious what the controller code was responsible for passing to where.

some_controller.rb

respond_to do |format|
  format.turbo_stream do
    render turbo_stream: [
      turbo_stream.replace(:flash, partial: "layouts/flash", locals: { notice: "Message posted!" }),
      turbo_stream.append(:messages, partial: "messages/message", locals: { message: message })
    ]
  end
end

some_view.html.erb

<%= turbo_stream.replace "flash" do %>
  <%= render partial: 'layouts/flash', locals: { notice: "Message posted!" } %>
<% end %>

<%= turbo_stream.append "messages" do %>
  <%= render partial: 'messages/messages', locals: { message: @message } %>
<% end %>
