Basic non-Lite WebSocket Application

[john]

I have written mojo lite based websocket applications but am having
problems with my first attempt at a full application:

https://github.com/john-/mojo_inotifier

Here is what happens::

morbo script/inotifier
Server available at http://127.0.0.1:3000

[Sun May 15 10:57:08 2016] [debug] 500 Internal Server Error (0.035149s,

in wsinit $self for this route is undef. This means to me I am doing
something wrong with my route definition:

$r->websocket('/wsinit')->to(controller => 'actions', action =>
'wsinit');

I tried alternate ways such as
"$r->websocket('/wsinit')->to('actions#wsinit');" with the same result.

What am I missing here?

Thanks,

John

Try changing Actions.pm, L13 from
my $self => shift;
to
my $self = shift;
?

Oh my goodness.   That was it.

Hi,
Sent you edits in github.
Looks like $self is undef because you have a typo when setting it in wsinit().
Also, looking at the docs it seems websocket() just creates a GET handler for the initial websocket handshake, if you want to actually send anything, you need to subscribe to a "message" event in your action.
