Respond with raw html tag in the action directly instead of use component or html.

[zw963]

Please check following example:

class Foo < BrowserAction
  get "/foo" do
    # I want render a <h1> tag above following Foo component.
    "<h1>Hello</h1>"
    component(Foo)
  end
end

I want to add a <h1> tag when response the html page, it is trivial to create a new component instead, and only use once, how to do that?

Thanks

get "/foo" do
  send_text_response("<h1>Hello</h1>", html_content_type)
end

Hi, I tested, but this method not work for me, the <h1> tag not appear in the page.

class Foo < BrowserAction
  get "/foo" do
   send_text_response("<h1>Hello</h1>", "text/html")
    component(Foo)
  end
end

You only need

class Foo < BrowserAction
  get "/foo" do
   send_text_response("<h1>Hello</h1>", "text/html")
  end
end

This would make the entire HTML response just <h1>Hello</h1> as a string. Don't use component here.

Sorry, what I expected to is, render a little piece raw html tag + a component in the action.

Sure I can extract the first little piece raw html tag into another component to achieve same effect, but, as I said before,
it probably very simple, not worth to create a new component for it.

so, is there a way to do this?

I don't know if I quite understand, but you can try this...

class Foo < BrowserAction
  get "/foo" do
   io = IO::Memory.new
   html_part = "<h1>Hello</h1>",
   comp = SomeComponent.new
   io << html_part
   comp.view(io)
   send_text_response(comp.render_to_string, "text/html")
  end
end

Though, I'd personally just make a single component that does this because it makes testing easier.
