Mojolicious::Guides - The Mojolicious Guide to the Galaxy
The Mojolicious documentation is structured into three parts. The "TUTORIAL" everyone starts with, the "GUIDES" that explain all major features in detail, and the class "REFERENCE" listing all available APIs.
Some parts of the documentation only use the Mojolicious::Lite micro web framework for examples, but that's merely a convenience for the reader. Almost all features are exactly the same for full Mojolicious applications.
If you are new to Perl, we recommend Learn Perl in 2 hours 30 minutes for a quick introduction, or the Modern Perl book, freely available in many formats. Both are excellent introductions to the language. For more books and documentation, check out learn.perl.org.
Mojolicious uses a modern subset of Perl exclusively, and therefore all documentation assumes that strict, warnings, utf8 and Perl 5.10 features are enabled, even if examples don't specifically mention it.
use strict; use warnings; use utf8; use feature ':5.10';
For brevity and clarity, example variables will reflect the type of data the API uses. For instance,
$chars to distinguish whether it is encoded bytes or decoded characters in a Perl string,
$bool if the value just indicates true or false,
$c to denote a Mojolicious::Controller object, or
$app to denote the application object.
A fast and fun way to get started developing web applications with Mojolicious. The tutorial introduces the Mojolicious::Lite micro web framework, which is only a thin wrapper around the full web framework. The simplified notation introduced in the tutorial is commonly used throughout the guides and is therefore considered a prerequisite, you should definitely take a look!

Answers to the most frequently asked questions.
Mojolicious and Mojolicious::Lite are the sum of many parts, built on top of the Mojo web development toolkit. Small building blocks that can be used independently for all kinds of applications, these are the most prominent ones.
Full featured non-blocking I/O HTTP and WebSocket user agent.
Very fun and minimalistic HTML/XML DOM parser with CSS selector support.
Minimalistic JSON implementation that just works.
Full featured, highly portable non-blocking I/O HTTP and WebSocket server, with self-restart support through Mojo::Server::Morbo, perfect for development and testing.
Full featured, UNIX optimized, preforking non-blocking I/O HTTP and WebSocket server with support for zero downtime software upgrades (hot deployment) through Mojo::Server::Hypnotoad.
Transparent CGI and PSGI support out of the box.
A minimalistic event loop with support for multiple reactor backends.
Very Perl-ish and minimalistic template system.
Testing toolkit for web applications.
Fun one-liners using everything above.
These modules are not part of the Mojolicious distribution, but have been designed to be used with it and are being developed under the same umbrella.
A tiny wrapper around DBD::Pg that makes PostgreSQL a lot of fun to use with Mojolicious. Perform queries blocking and non-blocking, use all SQL features PostgreSQL has to offer, generate CRUD queries from data structures, manage your database schema with migrations and build scalable real-time web applications with the publish/subscribe pattern.
And it comes with two great example applications you can use for inspiration. The minimal chat application will show you how to scale WebSockets to multiple servers, and the well-structured blog application how to apply the MVC design pattern in practice.
A full featured job queue for Mojolicious with support for multiple backends (such as PostgreSQL). Job queues allow you to process time and/or computationally intensive tasks in background processes, outside of the request/response lifecycle. Among those tasks you'll commonly find image resizing, spam filtering, HTTP downloads, building tarballs, warming caches and basically everything else you can imagine that's not super fast.
This is the class hierarchy of the Mojolicious distribution.
A lot more documentation and examples by many different authors can be found in the Mojolicious wiki.
