NAME
Routes::Tiny - Routes
SYNOPSIS
my $routes = Routes::Tiny->new;
# Constraints
$routes->add_route('/articles/:id', constraints => {id => qr/\d+/});
# Optional placeholders
$routes->add_route('/archive/:year/(:month)?');
# Defaults
$routes->add_route('/articles/:id',
defaults => {controller => 'bar', action => 'foo'});
# Grouping (matches 'hello-bar')
$routes->add_route('/(:foo)-bar');
# Globbing (matches 'photos/foo/bar/baz')
$routes->add_route('/photos/*other');
# Path building
$routes->add_route('/:foo/:bar', name => 'default');
$routes->build_path('default', foo => 'hello', bar => 'world');
# Matching
my $match = $routes->match('/hello/world');
my $captures_hashref = $match->captures;
# Matching with method
$routes->add_route('/hello/world', method => 'GET');
my $match = $routes->match('/hello/world', method => 'GET');
# Subroutes
my $subroutes = Routes::Tiny->new;
$subroutes->add_route('/article/:id');
$routes->mount('/admin/', $subroutes);
DESCRIPTION
Routes::Tiny is a lightweight routes implementation.
Routes::Tiny aims to be easy to use in any web framework.
FEATURES
Constraints
$routes->add_route('/articles/:id', constraints => {id => qr/\d+/});
$match = $routes->match('/articles/1'); # Routes::Tiny::Match object
$match = $routes->match('/article/foo'); # undef
It is possible to specify a constraint that a placeholder must match using a normal Perl regular expression.
Constraints can be passed as array references:
$routes->add_route('/articles/:action',
constraints => {action => [qw/add update/]});
$match = $routes->match('/articles/add'); # Routes::Tiny::Match object
$match = $routes->match('/articles/delete'); # undef
Optional placeholders
$routes->add_route('/admin/:service(/:action)?', defaults => {action => 'list'});
my $match = $routes->match('/admin/foo');
# $m->captures is {service => 'foo', action => 'list'}
It is possible to specify an optional placeholder with a default value.
Grouping
$routes->add_route('/(:foo)-bar');
$match = $routes->match('/hello-bar');
# $match->captures is {foo => 'hello'}
It is possible to create a placeholder that doesn't occupy all the space between slashes.
Globbing
$routes->add_route('/photos/*other');
$routes->add_route('/books/*section/:title');
$routes->add_route('/*a/foo/*b');
$match = $routes->match('photos/foo/bar/baz');
# $match->captures is {other => 'foo/bar/baz'}
$match = $routes->match('books/some/section/last-words-a-memoir');
# $match->captures is {section => 'some/section', title => 'last-words-a-memoir'}
$match = $routes->match('zoo/woo/foo/bar/baz');
# $match->captures is {a => 'zoo/woo', b => 'bar/baz'}
It is possible to specify a globbing placeholder.
Passing arguments AS IS
$routes->add_route('/', arguments => {one => 'two'});
$match = $routes->match('/');
# $match->arguments is {one => 'two'}
It is possible to pass arguments to the match object AS IS.
Matching with methods
# Exact HTTP method definition
$routes->add_route('/articles', method => 'GET', defaults => {action => 'list'});
# Sweeter method definition
# METHOD => PATTERN should go as first parameters to add_route()
$routes->add_route(PUT => '/articles', defaults => {action => 'create'});
$match = $routes->match('/articles', method => 'GET');
# $m->captures is {action => 'list'}
$match = $routes->match('/articles', method => 'PUT');
# $m->captures is {action => 'create'}
Subroutes
$subroutes = Routes::Tiny->new;
$subroutes->add_route('/articles/:id', name => 'admin-article');
$routes->mount('/admin/', $subroutes);
$match = $routes->match('/admin/articles/3/');
# $match->captures is {id => 3}
It is possible to capture params in mount routes
$subroutes = Routes::Tiny->new;
$subroutes->add_route('/comments/:page/', name => 'comments');
$routes->mount('/:type/:id/', $subroutes);
$match = $routes->match('/articles/3/comments/5/');
# $match->captures is {page => 5}
# $match->parent->captures is {type => 'articles', id => 3}
Parent routes mounts names of children routes, so it's possible to buil path
$path = $routes->build_path('admin-article', id => 123);
# $path is '/admin/articles/123'
$path = $routes->build_path('comments', type => 'articles', id => 123, page => 5);
# $path is '/articles/123/comments/5/'
Path building
$routes->add_route('/articles/:id', name => 'article');
$path = $routes->build_path('article', id => 123);
# $path is '/articles/123'
It is possible to reconstruct a path from route's name and parameters.
WARNINGS
Trailing slash issue
Trailing slash is important.
$routes->add_route('/articles');
# is different from
$routes->add_route('/articles/');
If you don't want this behaviour pass strict_trailing_slash
to the constructor:
my $routes = Routes::Tiny->new(strict_trailing_slash => 0);
Case sensitivity
Routes::Tiny is case sensitive by default (since 0.20).
It means that
$routes->add_route('/admin/');
will NOT match both /admin/
and /ADMIN/
.
If you don't want this behaviour pass strict_case
to the constructor:
my $routes = Routes::Tiny->new(strict_case => 0);
METHODS
new
my $routes = Routes::Tiny->new;
add_route
$routes->add_route('/:service/:action');
Add a new route.
mount
$routes->mount('/admin/', $subroutes)
Includes one Routes::Tiny instance into another with given prefix.
match
$routes->match('/hello/world');
Match against a path.
build_path
$pattern->build_path('name', {foo => 'bar'});
Build path from a given name and params.
