Note that the server uses signals for process management, so you should avoid modifying signal handlers in your applications. To start applications with it you can use the L script. $ morbo ./myapp.pl Web application available at http://127.0.0.1:3000 For better scalability (epoll, kqueue) and to provide non-blocking name resolution, SOCKS5 as well as TLS support, the optional modules L (4.32+), L (0.15+), L (0.64+) and L (2.009+) will be used automatically if possible. Individual features can also be disabled with the C, C and C environment variables. See L for more. =head1 SIGNALS The L process can be controlled at runtime with the following signals. =head2 INT, TERM Shut down server immediately. =head1 ATTRIBUTES L implements the following attributes. =head2 backend my $backend = $morbo->backend; $morbo = $morbo->backend(Mojo::Server::Morbo::Backend::Poll->new); Backend, usually a L object. =head2 daemon my $daemon = $morbo->daemon; $morbo = $morbo->daemon(Mojo::Server::Daemon->new); L object this server manages. =head2 silent my $bool = $morbo->silent; $morbo = $morbo->silent($bool); Disable console messages, defaults to a true value. =head1 METHODS L inherits all methods from L and implements the following new ones. =head2 run $morbo->run('script/my_app'); Run server for application and wait for L. =head1 SEE ALSO L, L, L. =cut
