where do I put code in Sinatra that I want to execute when the app is shutdown?

问题

I am using Sinatra for my webapp. I have some cleanup code that I want to execute when my app is being shutdown. Is there a hook for this in Sinatra or do I have to use a separate mechanism?

回答1:

Look at Kernel#at_exit, I don't see why it shouldn't work in a Sinatra app if you define a block like that somewhere in your main app file.

Update: According to matt's comment, you have to define your at_exit handler before requiring Sinatra.
