a little gem to provide a heartbeat for your app
MIT License
A tiny gem that installs a Rack middleware to respond to heartbeat requests. This saves you all the trouble of creating custom controllers, routes, and static files, and prevents your logs from bloating.
Add this line to your application's Gemfile:
gem 'rack-heartbeat'
And then execute:
$ bundle
Or install it yourself as:
$ gem install rack-heartbeat
Once the gem is installed, you're done. Just browse to http://localhost:3000/heartbeat to get a text response with "OK".
If you want to customize the url for any reason, you can configure that, too:
# config/initializers/rack_heartbeat.rb
Rack::Heartbeat.setup do |config|
config.heartbeat_path = 'health-check.txt'
end
You can also customize headers and response, for example if you want to do the cross-domain request, you can either set the CORS headers, or just send an image:
# config/initializers/rack_heartbeat.rb
Rack::Heartbeat.setup do |config|
config.heartbeat_response = Base64.decode64('R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==')
config.heartbeat_headers = {'Content-Type' => 'image/gif'}
end
