NAME
Mojolicious::Guides - The Mojolicious Guide to the Galaxy
DON'T PANIC!
The Mojolicious <https://mojolicious.org> documentation is structured into three parts. The ``TUTORIAL'' everyone
starts with, the ``GUIDES'' that explain all major features in detail, and the ``API'' reference listing all
available classes.
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.
BASICS
Learning Perl
If you are new to Perl, we recommend Learn Perl in 2 hours 30 minutes <https://qntm.org/perl_en> for a quick
introduction, or the Modern Perl book <https://pragprog.com/book/swperl/modern-perl-fourth-edition>, freely available
in many formats. Both are excellent introductions to the language. For more books and documentation, check out
learn.perl.org <https://learn.perl.org/>.
Learning Web Technologies
All web development starts with HTML, CSS and JavaScript, to learn the basics we recommend the Mozilla Developer
Network <https://developer.mozilla.org/en-US/docs/Web>. And if you want to know more about how browsers and web servers
actually communicate, there's also a very nice introduction to
HTTP <https://developer.mozilla.org/en-US/docs/Web/HTTP>.
CONVENTIONS
Modern Perl
Mojolicious uses a modern subset of Perl exclusively, and therefore all documentation assumes that strict,
warnings, utf8 and Perl 5.16 features are enabled, even if examples don't specifically mention it.
use strict;
use warnings;
use utf8;
use feature ':5.16';
Some modules, like Mojo::Base and Mojolicious::Lite, will enable them for you automatically, whenever they are
used.
Signatures
On Perl 5.20+ you can also use the "-signatures" flag with Mojo::Base to enable support for
subroutine signatures. Signatures are used in all examples for clarity, even when "-signatures"
is omitted for brevity.
Variable names
For brevity and clarity, example variables will reflect the type of data the API uses. For instance, $bytes or
$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.
TUTORIAL
- Mojolicious::Guides::Tutorial
-
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!
GUIDES
- Mojolicious::Guides::Growing
-
Starting a Mojolicious::Lite prototype from scratch and growing it into a well-structured Mojolicious
application.
- Mojolicious::Guides::Routing
-
Simple and fun introduction to the Mojolicious router.
- Mojolicious::Guides::Rendering
-
Generating content with the Mojolicious renderer.
- Mojolicious::Guides::Testing
-
Powerful yet elegant testing techniques and tools for Mojolicious and other web applications.
- Mojolicious::Guides::Cookbook
-
Cooking with Mojolicious, recipes for every taste.
- Mojolicious::Guides::Contributing
-
Become a part of the ongoing Mojolicious development.
- Mojolicious::Guides::FAQ
-
Answers to the most frequently asked questions.
HIGHLIGHTS
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.
- Mojo::UserAgent
-
Full featured non-blocking I/O HTTP and WebSocket user agent.
- Mojo::DOM
-
Very fun and minimalistic HTML/XML DOM parser with CSS selector support.
- Mojo::JSON
-
Minimalistic JSON implementation that just works.
- Mojo::Server::Daemon
-
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.
- Mojo::Server::Prefork
-
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.
- Mojo::Server::CGI, Mojo::Server::PSGI
-
Transparent CGI and PSGI support out of the box.
- Mojo::IOLoop
-
A minimalistic event loop with support for multiple reactor backends.
- Mojo::Template
-
Very Perl-ish and minimalistic template system.
- Test::Mojo
-
Testing toolkit for web applications.
- ojo
-
Fun one-liners using everything above.
FULL-STACK
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.
- Mojo::Pg
-
A tiny wrapper around DBD::Pg that makes PostgreSQL <https://www.postgresql.org> a lot of fun to use with
Mojolicious. Perform queries blocking and non-blocking, use all SQL
features <https://www.postgresql.org/docs/current/static/sql.html> 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.
Examples: The minimal chat <https://github.com/mojolicious/mojo-pg/tree/main/examples/chat.pl> application will
show you how to scale WebSockets to multiple servers, and the well-structured
blog <https://github.com/mojolicious/mojo-pg/tree/main/examples/blog> application how to apply the MVC design pattern
in practice.
- Minion
-
A full featured job queue for Mojolicious with support for multiple backends (such as
PostgreSQL <https://www.postgresql.org>). 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.
Examples: The link checker <https://github.com/mojolicious/minion/tree/main/examples/linkcheck> will show you how to
integrate background jobs into well-structured Mojolicious applications.
