NAME
Router::Boom - Fast routing engine for web applications
SYNOPSIS
use Router::Boom;
my $router = Router::Boom->new();
$router->add('/', 'dispatch_root');
$router->add('/entrylist', 'dispatch_entrylist');
$router->add('/:user', 'dispatch_user');
$router->add('/:user/{year}', 'dispatch_year');
$router->add('/:user/{year}/{month:\d+}', 'dispatch_month');
$router->add('/download/*', 'dispatch_download');
my $dest = $router->match($env->{PATH_INFO});DESCRIPTION
Router::Boom is a fast path routing engine for Perl5.
MEHTODS
- my $router = Router::Boom->new()
-
Create new instance.
- $router->add($path:Str, $destination:Any)
-
Add new route.
- my ($destination, $captured) = $router->match($path:Str);
-
Matching the route. If matching successfully, this method returns 2 values.
First: The destination value, you registered. Second: Captured values from the path.
If matching was failed, this method returns empty list.
HOW TO WRITE A ROUTING RULE
plain string
$router->add( '/foo', { controller => 'Root', action => 'foo' } );:name notation
$router->add( '/wiki/:page', { controller => 'WikiPage', action => 'show' } );
...
$router->match('/wiki/john');
# => {controller => 'WikiPage', action => 'show'}, {page => 'john'}':name' notation matches qr{([^/]+)}.
'*' notation
$router->add( '/download/*', { controller => 'Download', action => 'file' } );
...
$router->match('/download/path/to/file.xml');
# => {controller => 'Download', action => 'file'}, {'*' => 'path/to/file.xml'}'*' notation matches qr{(.+)}. You will get the captured argument as the special key: *.
'{year}' notation
$router->add( '/blog/{year}', { controller => 'Blog', action => 'yearly' } );
...
$router->match('/blog/2010');
# => {controller => 'Blog', action => 'yearly'}, {year => 2010}'{year}' notation matches qr{([^/]+)}, and it will be captured.
'{year:[0-9]+}' notation
$router->add( '/blog/{year:[0-9]+}/{month:[0-9]{2}}', { controller => 'Blog', action => 'monthly' } );
...
$router->match('/blog/2010/04');
# => {controller => 'Blog', action => 'monthly'}, {year => 2010, month => '04'}You can specify regular expressions in named captures.
Note. You can't include normal capture in custom regular expression. i.e. You can't use {year:(\d+)} . But you can use {year:(?:\d+)}.
PERFORMANCE
Router::Boom is pretty fast!
Rate Router::Simple Router::Boom
Router::Simple 8000/s -- -90%
Router::Boom 83651/s 946% --Router::Boom's computational complexity is not linear scale, bug Router::Simple's computational complexity is linear scale.
Then, Router::Simple get slower if registered too much routes. But if you're using Router::Boom then you don't care the performance :)

Router::Simple is my old one. But it's bit slow and complicated.
Path::Dispatcher is similar, but so complex.
Path::Router is heavy. It depends on Moose.
HTTP::Router has many dependencies. It is not well documented.
HTTPx::Dispatcher is my old one. It does not provide an OO-ish interface.
