Mojolicious::Lite - Micro real-time web framework
# Automatically enables "strict", "warnings", "utf8" and Perl 5.16 features use Mojolicious::Lite -signatures; # Route with placeholder get '/:foo' => sub ($c) { my $foo = $c->param('foo'); $c->render(text => "Hello from $foo."); }; # Start the Mojolicious command system app->start;
Mojolicious::Lite is a tiny domain specific language built around Mojolicious, made up of only about a dozen Perl functions.
On Perl 5.20+ you can also use a "-signatures" flag to enable support for subroutine signatures.
use Mojolicious::Lite -signatures; get '/:foo' => sub ($c) { my $foo = $c->param('foo'); $c->render(text => "Hello from $foo."); }; app->start;
See Mojolicious::Guides::Tutorial for more!
While Mojolicious::Guides::Growing will give you a detailed introduction to growing a Mojolicious::Lite prototype into a well-structured Mojolicious application, here we have collected a few snippets that illustrate very well just how similar both of them are.
The functions "get", "post" and friends all have equivalent methods.
# Mojolicious::Lite get '/foo' => sub ($c) { $c->render(text => 'Hello World!'); }; # Mojolicious sub startup ($self) { my $routes = $self->routes; $routes->get('/foo' => sub ($c) { $c->render(text => 'Hello World!'); }); }
The application object you can access with the function "app" is the first argument passed to the "startup" method.
# Mojolicious::Lite app->max_request_size(16777216); # Mojolicious sub startup ($self) { $self->max_request_size(16777216); }
Instead of the "plugin" function you just use the method "plugin" in Mojolicious.
# Mojolicious::Lite plugin 'Config'; # Mojolicious sub startup ($self) { $self->plugin('Config'); }
Similar to plugins, instead of the "helper" function you just use the method "helper" in Mojolicious.
# Mojolicious::Lite helper two => sub ($c) { return 1 + 1; }; # Mojolicious sub startup ($self) { $self->helper(two => sub ($c) { return 1 + 1; }); }
Instead of sequential function calls, we can use methods to build a tree with nested routes, that much better illustrates how routes work internally.
# Mojolicious::Lite under '/foo'; get '/bar' => sub ($c) {...}; # Mojolicious sub startup ($self) { my $routes = $self->routes; my $foo = $routes->under('/foo'); $foo->get('/bar' => sub ($c) {...}); }
Mojolicious::Lite implements the following functions, which are automatically exported.
my $route = any '/:foo' => sub ($c) {...}; my $route = any '/:foo' => sub ($c) {...} => 'name'; my $route = any '/:foo' => {foo => 'bar'} => sub ($c) {...}; my $route = any '/:foo' => [foo => qr/\w+/] => sub ($c) {...}; my $route = any ['GET', 'POST'] => '/:foo' => sub ($c) {...}; my $route = any ['GET', 'POST'] => '/:foo' => [foo => qr/\w+/] => sub ($c) {...}; my $route = any ['GET', 'POST'] => '/:foo' => (agent => qr/Firefox/) => sub ($c) {...};
Generate route with "any" in Mojolicious::Routes::Route, matching any of the listed HTTP request methods or all. See Mojolicious::Guides::Tutorial and Mojolicious::Guides::Routing for more information.
my $app = app;
Returns the Mojolicious::Lite application object, which is a subclass of Mojolicious.
# Use all the available attributes and methods app->log->level('error'); app->defaults(foo => 'bar');
my $route = del '/:foo' => sub ($c) {...}; my $route = del '/:foo' => sub ($c) {...} => 'name'; my $route = del '/:foo' => {foo => 'bar'} => sub ($c) {...}; my $route = del '/:foo' => [foo => qr/\w+/] => sub ($c) {...}; my $route = del '/:foo' => (agent => qr/Firefox/) => sub ($c) {...};
Generate route with "delete" in Mojolicious::Routes::Route, matching only "DELETE" requests. See Mojolicious::Guides::Tutorial and Mojolicious::Guides::Routing for more information.
