Back in the early days of the web, many people learned Perl because of a wonderful Perl library called CGI. It was simple enough to get started without knowing much about the language and powerful enough to keep you going, learning by doing was much fun. While most of the techniques used are outdated now, the idea behind it is not. Mojolicious is a new endeavor to implement this idea using bleeding edge technologies.
All you need is a one-liner, it takes less than a minute.
$ curl -L https://cpanmin.us | perl - -M https://cpan.metacpan.org -n Mojolicious
We recommend the use of a Perlbrew environment.
These three lines are a whole web application.
use Mojolicious::Lite;
get '/' => {text => 'I ♥ Mojolicious!'};
app->start;
To run this example with the built-in development web server just put
the code into a file and start it with morbo
.
$ morbo hello.pl
Server available at http://127.0.0.1:3000
$ curl http://127.0.0.1:3000/
I ♥ Mojolicious!
Use all the latest Perl and HTML features in beautiful single file prototypes like this one, and grow them easily into well-structured applications.
use Mojolicious::Lite;
use 5.20.0;
use experimental 'signatures';
# Render template "index.html.ep" from the DATA section
get '/' => {template => 'index'};
# WebSocket service used by the template to extract the title from a web site
websocket '/title' => sub ($c) {
$c->on(message => sub ($c, $msg) {
my $title = $c->ua->get($msg)->res->dom->at('title')->text;
$c->send($title);
});
};
app->start;
__DATA__

% my $url = url_for 'title';
<script>
var ws = new WebSocket('<%= $url->to_abs %>');
ws.onmessage = function (event) { document.body.innerHTML += event.data };
ws.onopen = function (event) { ws.send('http://mojolicious.org') };
</script>
