Hotwire

[palkan]

Hotwire allows use to leverage HTML-over-the-Wire as much as possible and get rid of unnecessary JavaScript.

What's in a poke

• Migrate items deletion and completion to Turbo Frames
• Migrate real-time list updates to Turbo Streams with a bit of Stimulus (via stimulus-use)
• Migrate chat to AJAX, Turbo Streams and custom elements

Suggested change

	flash.now[:notice] = "Item has been updated"
	render partial: "update", locals: {item}, content_type: "text/vnd.turbo-stream.html"
	respond_to do |format|
	format.turbo_stream do
	render partial: "update", locals: {item}
	end
	format.html do
	flash[:notice] = "Item has been updated"
	redirect_to workspace
	end
	end

Untested! But I think this addresses the I found that Turbo expects HTTP response to have the text/vnd.turbo-stream.html content type in order to activate stream elements confusion in your (great!) article. See the Turbo::StreamsHelper documentation for more.

I rewrote this part a bit: 860c706

Sweet! Maybe update your blog post too?

Already updated)

I was thinking of this section in particular:

The preferred way to respond with Turbo Streams in Rails is with implicit .turbo_stream.erb templates (e.g. 860c706) and/or format.turbo_stream { … } (in respond_to) blocks. They set the custom response content type automatically.

Will it work without respond_to? I mean: render turbo_stream: "update", locals: ....

[javan]

Does locals: {item} expand to locals: {item: item} somehow or is this a JavaScript-brain typo?

That's right, @javan. In ES6, there's a shorthand version for properties with a value coming from a variable with the same name. So, having { item } will is the same as writing { item: item }

[javan]

This is a Ruby file though

[iguanus]

/facepalm. You are right.

Yes, via Ruby Next 🙂

It's a proposed feature: https://bugs.ruby-lang.org/issues/15236
