Let it crash
A Go middleware to display debug information when an application is in a panic situation or needs to handle an error.
This middleware contains:
- An enhanced console output of the error stacktrace using panicparse
- An HTML debug error page which contains stacktrace and various information about request, environment, etc.
Do not use this middleware in production :)
