    # Mojolicious
    $self->plugin('Narada');
    $self->plugin(Narada => (log => Log::Fast->global));

    # Mojolicious::Lite
    plugin 'Narada';
    plugin Narada => (log => Log::Fast->global);

    # Global timer
    package MyApp;
    sub startup {
        my $app = shift;
        Mojo::IOLoop->timer(0 => $app->proxy(sub { say 'Next tick.' }));

    sub myaction {
        my $c = shift;
        $c->render_later;
        Mojo::IOLoop->timer(1 => $c->weak_proxy(sub { say 'Alive' }));

              $c->render(text => 'Delayed by 2 seconds!');

DESCRIPTION

Mojolicious::Plugin::Narada is a plugin that configure Mojolicious to work in Narada project management environment.

Also this plugin add helpers proxy and weak_proxy, and you MUST use them to wrap all callbacks you setup for handling delayed events like timers or I/O (both global in your app and related to requests in your actions).

There is also one feature unrelated to Narada - if callback started by any action throw unhandled exception it will be sent to browser using same $c->reply->exception as it already works for actions without delayed response.

Logging

Mojolicious default Mojo::Log replaced with MojoX::Log::Fast to support logging to project-local syslog daemon in addition to files. In most cases it works as drop-in replacement and doesn't require any modifications in user code.

Also it set $app->log->ident() to $c->req->url->path to ease log file analyse.

Configuration

You should manually add these lines to ./you_app starting script before call to Mojolicious::Commands->start_app():

    use Narada::Config qw( get_config_line );
    # mode should be set here because it's used before executing MyApp::startup()
    local $ENV{MOJO_MODE} = get_config_line('mode');

Config file config/cookie.secret automatically loaded and used to initialize $app->secrets() (each line of file became separate param).

Config file config/basepath automatically loaded and used to fix $c->req->url->base->path and $c->req->url->path to guarantee their consistency in any environment:

  • url->path doesn't contain base->path

  • url->path does have leading slash

  • url->base->path set to content of config/basepath

These config files automatically loaded from config/hypnotoad/* and used to initialize $app->config(hypnotoad):

    listen
    proxy
    accepts
    workers

Also hypnotoad configured to keep it lock/pid files in var/.

Locking

unlock() will be automatically called after all actions and callbacks, even if they throw unhandled exception.
