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 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 and Better Errors for Ruby https://github.com/charliesome/better_errors.
