NAME

6       Mojolicious::Guides - The Mojolicious Guide to the Galaxy
7

DON'T PANIC!

9       The Mojolicious <https://mojolicious.org> documentation is structured
10       into three parts. The "TUTORIAL" everyone starts with, the "GUIDES"
11       that explain all major features in detail, and the "API" reference
12       listing all available classes.
13
14       Some parts of the documentation only use the Mojolicious::Lite micro
15       web framework for examples, but that's merely a convenience for the
16       reader. Almost all features are exactly the same for full Mojolicious
17       applications.

BASICS

20   Learning Perl
21       If you are new to Perl, we recommend Learn Perl in 2 hours 30 minutes
22       <https://qntm.org/perl_en> for a quick introduction, or the Modern Perl
23       book <https://pragprog.com/book/swperl/modern-perl-fourth-edition>,
24       freely available in many formats. Both are excellent introductions to
25       the language. For more books and documentation, check out
26       learn.perl.org <https://learn.perl.org/>.
27
28   Learning Web Technologies
29       All web development starts with HTML, CSS and JavaScript, to learn the
30       basics we recommend the Mozilla Developer Network
31       <https://developer.mozilla.org/en-US/docs/Web>. And if you want to know
32       more about how browsers and web servers actually communicate, there's
33       also a very nice introduction to HTTP
34       <https://developer.mozilla.org/en-US/docs/Web/HTTP>.
35

CONVENTIONS

37   Modern Perl
38       Mojolicious uses a modern subset of Perl exclusively, and therefore all
39       documentation assumes that strict, warnings, utf8 and Perl 5.16
40       features are enabled, even if examples don't specifically mention it.
41
42         use strict;
43         use warnings;
44         use utf8;
45         use feature ':5.16';
46
47       Some modules, like Mojo::Base and Mojolicious::Lite, will enable them
48       for you automatically, whenever they are used.
49
50   Signatures
51       On Perl 5.20+ you can also use the "-signatures" flag with Mojo::Base
52       to enable support for subroutine signatures. Signatures are used in all
53       examples for clarity, even when "-signatures" is omitted for brevity.
54
55   Variable names
56       For brevity and clarity, example variables will reflect the type of
57       data the API uses. For instance, $bytes or $chars to distinguish
58       whether it is encoded bytes or decoded characters in a Perl string,
59       $bool if the value just indicates true or false, $c to denote a
60       Mojolicious::Controller object, or $app to denote the application
61       object.
62

TUTORIAL

64       Mojolicious::Guides::Tutorial
65         A fast and fun way to get started developing web applications with
66         Mojolicious. The tutorial introduces the Mojolicious::Lite micro web
67         framework, which is only a thin wrapper around the full web
68         framework. The simplified notation introduced in the tutorial is
69         commonly used throughout the guides and is therefore considered a
70         prerequisite, you should definitely take a look!

HIGHLIGHTS

97       Mojolicious and Mojolicious::Lite are the sum of many parts, built on
98       top of the Mojo web development toolkit.  Small building blocks that
99       can be used independently for all kinds of applications, these are the
100       most prominent ones.
101
102       Mojo::UserAgent
103         Full featured non-blocking I/O HTTP and WebSocket user agent.
104
105       Mojo::DOM
106         Very fun and minimalistic HTML/XML DOM parser with CSS selector
107         support.
108
109       Mojo::JSON
110         Minimalistic JSON implementation that just works.
111
112       Mojo::Server::Daemon
113         Full featured, highly portable non-blocking I/O HTTP and WebSocket
114         server, with self-restart support through Mojo::Server::Morbo,
115         perfect for development and testing.
116
117       Mojo::Server::Prefork
118         Full featured, UNIX optimized, preforking non-blocking I/O HTTP and
119         WebSocket server with support for zero downtime software upgrades
120         (hot deployment) through Mojo::Server::Hypnotoad.
121
122       Mojo::Server::CGI, Mojo::Server::PSGI
123         Transparent CGI and PSGI support out of the box.
124
125       Mojo::IOLoop
126         A minimalistic event loop with support for multiple reactor backends.
127
128       Mojo::Template
129         Very Perl-ish and minimalistic template system.
130
131       Test::Mojo
132         Testing toolkit for web applications.
133
134       ojo
135         Fun one-liners using everything above.

FULL-STACK

138       These modules are not part of the Mojolicious distribution, but have
139       been designed to be used with it and are being developed under the same
140       umbrella.
141
142       Mojo::Pg
143         A tiny wrapper around DBD::Pg that makes PostgreSQL
144         <https://www.postgresql.org> a lot of fun to use with Mojolicious.
145         Perform queries blocking and non-blocking, use all SQL features
146         <https://www.postgresql.org/docs/current/static/sql.html> PostgreSQL
147         has to offer, generate CRUD queries from data structures, manage your
148         database schema with migrations and build scalable real-time web
149         applications with the publish/subscribe pattern.
150
151         Examples: The minimal chat <https://github.com/mojolicious/mojo-
152         pg/tree/main/examples/chat.pl> application will show you how to scale
153         WebSockets to multiple servers, and the well-structured blog
154         <https://github.com/mojolicious/mojo-pg/tree/main/examples/blog>
155         application how to apply the MVC design pattern in practice.
156
157       Minion
158         A full featured job queue for Mojolicious with support for multiple
159         backends (such as PostgreSQL <https://www.postgresql.org>). Job
160         queues allow you to process time and/or computationally intensive
161         tasks in background processes, outside of the request/response
162         lifecycle. Among those tasks you'll commonly find image resizing,
163         spam filtering, HTTP downloads, building tarballs, warming caches and
164         basically everything else you can imagine that's not super fast.
165
166         Examples: The link checker
167         <https://github.com/mojolicious/minion/tree/main/examples/linkcheck>
168         will show you how to integrate background jobs into well-structured
169         Mojolicious applications.
