Introduction

In this tutorial we learn how to install libplack-middleware-logerrors-perl on Debian 9.

What is libplack-middleware-logerrors-perl

libplack-middleware-logerrors-perl is:

psgi.errors defaults to stderr in most backends, which results in content going somewhere unhelpful like the server console.

Plack::Middleware::LogErrors simply remaps the psgi.errors stream to the psgix.logger stream, or an explicit logger that you provide.

This is especially handy when used in combination with other middlewares such as Plack::Middleware::LogWarn (which diverts Perl warnings to psgi.errors); Plack::Middleware::HTTPExceptions (which diverts uncaught exceptions to psgi.errors); and Plack::Middleware::AccessLog, which defaults to psgi.errors when not passed a logger – which is also automatically applied via plackup (so if you provided no –access-log option indicating a filename, psgi.errors is used).

Plack is a set of tools similar to Ruby’s Rack or Python’s Paste for WSGI. It implements the Perl Server Gateway Interface (PSGI) standard interface, which allows developers to decouple their web application framework from the local web server environment.
