react_helper.rb

module ReactHelper
  def render_react_component(component:, props: {}, dom_id:)
    <<-REACT_DOM_RENDER.strip_heredoc.squish.html_safe
      ReactDOM.render(
        React.createElement(#{sanitize(component)}, #{raw json_escape(props.to_json)}),
        document.getElementById("#{sanitize(dom_id)}")
      );
    REACT_DOM_RENDER
  end
end
