The book is based on the material of the most popular Perl Tutorial found on the Perl Maven site. Its creation was supported by 100 people in a crowdfunding campaign in March 2018. The book covers the basics of the Perl programming language. It introduces all the concepts you need to know to put together a Perl script or take apart one written by someone else.

The book explains both the plain Perl version of doing things if you need to maintain Perl code running on an older version of Perl. It also shows you modern, cleaner and shorter approaches for when you have the freedom to use a recent version of Perl and CPAN modules.

Perl Dancer is a modern, light-weight, route-based web framework written in Perl. It has been around since 2009. It is robust and can make it very easy to build solutions.

This book assumes basic Perl knowledge and some familiarity with the web. It starts from the beginning and takes you all the way deploying your application on a cloud-based service.

Dancer makes it very easy to build a REST-based API in front of a Microservice that can be used by other services in the company or that can be the back-end of a Single Page Application. Reading the book will help you understand these techniques and technologies. Doing the exercises that come with the book will ensure that you can implement such a service.

Markua is Markdown-inspired format created by Peter Armstrong to write books. It is used by LeanPub, the company where this book is published. Heck, even this book is written using the Markua format.

LeanPub has its own Markua parser written in Ruby.

This book follows the development of a Markua parser written in Perl.

As a reader of this book you will learn how to develop an application using TDD - Test Driven Development. That is, before every change we are going to create a test-case.

You will see how to set up Continuous Integration (CI) and how to monitor the test coverage.

As every development process it won't be without mistakes and setback. We will certainly see bugs being introduced and then fixed. Imperfect code written and then refactored.

In a nutshell, you will be able to see first-hand many of the best practices of today's development process.
