Mojolicious

1. Mojolicious. Веб в коробке! Анатолий Шарифулин

5. Что такое Mojolicious?

6. Что такое Mojolicious? • Pure Perl веб-фреймворк • Без зависимостей (с версии Perl 5.8.1) • Объектно-ориентированное API (без скрытой магии) • Поддержка HTTP 1.1, WebSocket, IPv6, SSL, IDNA • Поддержка CGI, FastCGI, PSGI, Daemon и Prefork • Веб-фреймворки: Mojo, Mojolicious и Mojolicious::Lite

7. «Fresh code, based upon years of expirience developing Catalyst»

9. Pure Perl веб-фреймворк

10. • Mojo::Base • Mojo::ByteStream • Mojo::Template, Mojo::JSON • Mojo::Loader, Mojo::Log, Mojo::Path • Mojo::URL, Mojo::Parameters, Mojo::Content • Mojo::Message::Request, Mojo::Message::Response, Mojo::Headers, Mojo::Cookie, Mojo::Date

12. Mojo::Base Minimal Base Class For Mojo Projects

13. package App; use base ‘Mojo::Base’; __PACKAGE__->attr(conf => sub { return do ‘conf/app.conf’; }); __PACKAGE__->attr(db => sub { my $self = shift; return Util->db($self->conf->{'db'}); }); sub dispatch { ... }

17. Mojo::ByteStream ByteStream

18. use Mojo::ByteStream; my $s = Mojo::ByteStream->new('foo_bar'); $s->camelize; $s->decamelize; $s->b64_encode; $s->b64_decode; $s->encode('utf8'); $s->decode('utf8'); $s->html_escape; $s->html_unescape; $s->qp_encode; $s->qp_decode; $s->quote; $stream->unquote; $s->url_escape; $s->url_unescape; $s->xml_escape; $s->punycode_encode; $s->punycode_decode;

19. use Mojo::ByteStream 'b'; my $s = b('foo_bar'); $s->camelize; $s->decamelize; $s->b64_encode; $s->b64_decode; $s->encode('utf8'); $s->decode('utf8'); $s->html_escape; $s->html_unescape; $s->qp_encode; $s->qp_decode; $s->quote; $stream->unquote; $s->url_escape; $s->url_unescape; $s->xml_escape; $s->punycode_encode; $s->punycode_decode;

30. Mojo::Template Perlish Templates!

31. % my $list = $self->stash(‘list’); <ul> % for (@$list) { <li> <%= $_->{title} %> </li> %} </ul> <p><%# comment %></p>

34. % my $count = 10 * 5; <ul> % for (@$list) { <li> <%= $_->{title} %> </li> %} </ul> <p><%# comment %></p>

35. % use Foo::Bar; <ul> % for (@$list) { <li> <%= $_->{title} %> </li> %} </ul> <p><%# comment %></p>

37. % my $list = $self->stash(‘list’); <ul> % if (@$list) { <li> <%= $_->{title} %> </li> %} </ul> <p><%# comment %></p>

40. % my $list = $self->stash(‘list’); <ul> % for (@$list) { <li> <%== $_->{title} %> </li> %} </ul> <p><%# comment %></p>

41. % my $list = $self->stash(‘list’); <ul> % for (@$list) { <li> <%= ucﬁrst $_->{title} %> </li> %} </ul> <p><%# comment %></p>

44. 1 % my $list = $self->stash(‘list’); 2 3 <ul> 4 % for (@$list) { 5 <li> 6 <%= $_->{title} xx %> 7 </li> 8 %} 9 </ul> 10 11 <p><%# comment %></p>

45. Сообщение об ошибке Bareword "xx" not allowed while "strict subs" in use at template line 6.

46. Простота PHP, мощь Perl

48. Mojo::JSON Minimalistic JSON

49. my $json = Mojo::JSON->new; my $string = $json->encode({foo => ‘bar’}); my $hash = $json->decode(‘{"foo":"bar"}’);

50. my $json = Mojo::JSON->new; my $string = $json->encode({foo => ‘bar’}); my $hash = $json->decode(‘{"foo":"bar"}’);

52. Mojo::Loader Class loader: load, reload, search

56. • Mojo::Trasaction • Mojo::IOLoop • Mojo::Client, Mojo::Server • Mojo::Server::CGI, Mojo::Server::FastCGI • Mojo::Server::PSGI • Mojo::Server::Daemon и ::Prefork • Mojo::Command • Mojo::Command::Generate и ~ Server

59. Mojo::IOLoop Minimalistic Reactor For TCP Clients And Servers

60. Mojo::IOLoop Поддержка IO::KQueue, IO::Epoll, IO::Socket::INET6 и IO::Socket::SSL

61. my $loop = Mojo::IOLoop->new; $loop->listen(port => 3000, cb => sub { my ($self, $id) = @_; $self->read_cb ($id => sub { ... }); $self->write_cb($id => sub { ... }); ); my $id = $loop->connect(port => 3000, ...); $loop->start; $loop->stop;

66. Mojo::Client Async IO HTTP 1.1 And WebSocket Client

67. my $client = Mojo::Client->new; $client->get( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

68. my $client = Mojo::Client->new; $self->client->get( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

70. my $client = Mojo::Client->new; $client->head( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

71. my $client = Mojo::Client->new; $client->post( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

72. my $client = Mojo::Client->new; $client->put( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

73. my $client = Mojo::Client->new; $client->async->get( ‘http://goo.gl’ => sub { my ($self, $tx) = @_; say $tx->res; } )->process;

77. my $client = Mojo::Client->new; $client->get(‘http://goo.gl’)->res->code; $client->get( 'http://search.twitter.com/trends.json' )->success->json->{trends}->[0]->{name}

78. my $client = Mojo::Client->new; $client->get(‘http://goo.gl’)->res->code; $client->get( 'http://search.twitter.com/trends.json' )->success->json->{trends}->[0]->{name}
