# NAME Plack::Middleware::BetterStackTrace - Displays better stack trace when your app dies # SYNOPSIS enable 'BetterStackTrace', application_caller_subroutine => 'Amon2::Web::handle_request'; # DESCRIPTION This middleware catches exceptions (run-time errors) happening in your application and displays nice stack trace screen. The stack trace is also stored in the environment as a plaintext and HTML under the key `plack.stacktrace.text` and `plack.stacktrace.html` respectively, so that middleware futher up the stack can reference it. You're recommended to use this middleware during the development and use [Plack::Middleware::HTTPExceptions](http://search.cpan.org/perldoc?Plack::Middleware::HTTPExceptions) in the deployment mode as a replacement, so that all the exceptions thrown from your application still get caught and rendered as a 500 error response, rather than crashing the web server. Catching errors in streaming response is not supported. This module is based on [Plack::Middleware::StackTrace](http://search.cpan.org/perldoc?Plack::Middleware::StackTrace) and Better Errors for Ruby [https://github.com/charliesome/better\_errors](https://github.com/charliesome/better\_errors). # LICENSE Perl Copyright (C) Tasuku SUENAGA a.k.a. gunyarakun.
