Plack Handbook - Intro

Introduction

This little handbook is based on the content of the Plack Advent Calendar website. The calendar had 24 useful short posts explaining the concept of PSGI and how to adapt existing web applications to Plack.

The calendar was so successful it's been considered a canonical reference for many beginners trying to learn Plack and for web framework authors trying to adapt their code to work with PSGI.

But the content was written 3 years ago and some of it is a little dated. In this book I tried to get it correct and up-to-date, and it will continue to be updated as we find errata and get feedback from the reader community.

Raw source code of the book, in Markdown format, is available on GitHub repository under the Creative Commons license. See the LICENSE file for details.
