1. Perl Meets SlackRTM Shoichi Kaji
2. SlackRTM?
3. SlackRTM • RTM = Real Time Messaging API • A websocket-based API that allows you to receive events (message, user_change, …)
 from Slack in real time • You can write BOTs as much as you want
4. Let’s use SlackRTM with Perl!
5. • There already exist awesome cpan modules • AnyEvent::SlackRTM by HANENKAMP • AnySan::Provider::Slack by SHOGO
6. But I created yet another…
7. Mojo::SlackRTM https://github.com/skaji/Mojo-SlackRTM
8. Why mojo? • Yes, Mojo is a web application framework. But it can be also a framework for event-driven programing • Has non-blocking http/websocket clients, and event loops • JSON everywhere • websocket has “json” event • http request/response treats json specially • Supports JSON Pointer notation
9. Eg use Mojo::SlackRTM; my $slack = Mojo::SlackRTM->new(token => $ENV{TOKEN}); $slack->on(message => sub { my ($slack, $event) = @_; my $channel_id = $event->{channel}; my $user_id = $event->{user}; my $user_name = $slack->find_user_name($user_id); $slack->send_message($channel_id => "hello $user_name!"); }); $slack->start;
10. Conclusion • SlackRTM is a websocket-based real time messaging API • Perl ❤ SlackRTM with AnyEvent::SlackRTM, AnySan::Provider::Slack, Mojo::SlackRTM • Mojo is a framework not only for web but also for event-driven programming
