ForgeBox with Santa hat Today let's look at a quick, fun module today. It will make your exception experience in development just a little bit nicer. It's called [`whoops`](https://www.forgebox.io/view/whoops).

whoops

Based off of the PHP package of the same name, whoops is a development exception experience. It shows an interactive stack trace, the code in question with the line highlighted, and some application and request information to help you track down problems in your application.

This is a module that is better told in pictures:

Get Started

It couldn't be easier to get started:

CommandBox> install whoops --saveDev

Happy debugging!

Hey, could you provide a bit more info on this...is it a CB only, or can it run with FW/1, or non-framework code? I guess you cd into your project then install woops? then when you run your code, it will fire off woops in the browser when/if it finds an error, and then brings up the code? Just wondering how to use it beyond just the pics...want to see if it is something for us at work or not... thanks

Hi, Dan. This is currently ColdBox only, as it uses the onError interception point. It likely could be extended easily to use the Application.cfc onError lifecycle method.
