NOTE: As it goes with all middleware that modifies the response, not compatible with Rails' streaming responses because it modifies the response.
Add this line to your application's Gemfile:
gem 'rack-toolbar'And then execute:
$ bundle
Or install it yourself as:
$ gem install rack-toolbar
If your app is delivering a response like:
<html>
<head></head>
<body>
<h1>Important</h1>
</body>
</html>
You want to inject something into the response!
Configure your app to use Rack::Toolbar
use Rack::Toolbar, {snippet: "<div>More Important!</div>", insertion_point: "<body>", insertion_method: :after}
The div specified will be injected :after the <body tag.
<html>
<head></head>
<body>
<div>More Important!</div>
<h1>Important</h1>
</body>
</html>
You want to build a Middleware that will deliver a custom response based on whatever.
Create your middleware to inherit from Rack::Toolbar, and define a render method:
class CustomMiddleware < Rack::Toolbar
def render
"<script>javascript:void(0)</script>"
end
end
Configure your app to use your CustomMiddleware. You can still use the :insertion_* options, but :snippet will be ignored.
use CustomMiddleware, {insertion_point: "</head>", insertion_method: :before}
