9 # Automatically enables "strict", "warnings", "utf8" and Perl 5.16 features
10 use Mojolicious::Lite -signatures;
11
12 # Route with placeholder
13 get '/:foo' => sub ($c) {
14 my $foo = $c->param('foo');
15 $c->render(text => "Hello from $foo.");

19 app->start;
20
22 Mojolicious::Lite is a tiny domain specific language built around
23 Mojolicious, made up of only about a dozen Perl functions.
24
25 On Perl 5.20+ you can also use a "-signatures" flag to enable support
26 for subroutine signatures.
27
28 use Mojolicious::Lite -signatures;
29
30 get '/:foo' => sub ($c) {
31 my $foo = $c->param('foo');
32 $c->render(text => "Hello from $foo.");
33 };
34
35 app->start;

37 See Mojolicious::Guides::Tutorial for more!

40 While Mojolicious::Guides::Growing will give you a detailed
41 introduction to growing a Mojolicious::Lite prototype into a well-
42 structured Mojolicious application, here we have collected a few
43 snippets that illustrate very well just how similar both of them are.
44
45 Routes
46 The functions "get", "post" and friends all have equivalent methods.
47
48 # Mojolicious::Lite
49 get '/foo' => sub ($c) {
50 $c->render(text => 'Hello World!');
51 };
52
53 # Mojolicious
54 sub startup ($self) {
55
56 my $routes = $self->routes;
57 $routes->get('/foo' => sub ($c) {
58 $c->render(text => 'Hello World!');
59 });
60 }
61
62 Application
63 The application object you can access with the function "app" is the
64 first argument passed to the "startup" method.
65
66 # Mojolicious::Lite
67 app->max_request_size(16777216);
68
69 # Mojolicious
70 sub startup ($self) {
71 $self->max_request_size(16777216);
72 }
73
74 Plugins
75 Instead of the "plugin" function you just use the method "plugin" in
76 Mojolicious.
77
78 # Mojolicious::Lite
79 plugin 'Config';
80
81 # Mojolicious
82 sub startup ($self) {
83 $self->plugin('Config');
84 }
85
86 Helpers
87 Similar to plugins, instead of the "helper" function you just use the
88 method "helper" in Mojolicious.
89
90 # Mojolicious::Lite
91 helper two => sub ($c) {
92 return 1 + 1;
93 };
94
95 # Mojolicious
96 sub startup ($self) {
97 $self->helper(two => sub ($c) {
98 return 1 + 1;
99 });
100 }
101
102 Under
103 Instead of sequential function calls, we can use methods to build a
104 tree with nested routes, that much better illustrates how routes work
105 internally.
106
107 # Mojolicious::Lite
108 under '/foo';
109 get '/bar' => sub ($c) {...};
110
111 # Mojolicious
112 sub startup ($self) {
113
114 my $routes = $self->routes;
115 my $foo = $routes->under('/foo');
116 $foo->get('/bar' => sub ($c) {...});
117 }
118
120 Mojolicious::Lite implements the following functions, which are
121 automatically exported.
122
123 any
124 my $route = any '/:foo' => sub ($c) {...};
125 my $route = any '/:foo' => sub ($c) {...} => 'name';

127 my $route = any '/:foo' => [foo => qr/\w+/] => sub ($c) {...};
128 my $route = any ['GET', 'POST'] => '/:foo' => sub ($c) {...};
129 my $route = any ['GET', 'POST'] => '/:foo' => [foo => qr/\w+/] => sub ($c) {...};

131
132 Generate route with "any" in Mojolicious::Routes::Route, matching any
133 of the listed HTTP request methods or all. See
