Re^4: Mojolicious Websocket example

Well, that would explain, now I put scripts into public directory and everything is working like a charm. Thank you

Now I am trying to build an application that will let's say every second check the DB or file and if there is some new value, will send it via websocket to thebrowsers. So, I wrote a script that send a message ( date and time). I am able to send it once, but how to put it into the loop? How to check the DB every seconds or every few seconds and send that data via WS?

here is the code that sends single message:

#!/usr/bin/env perl
use warnings;
use strict;
use Mojolicious::Lite;

get '/' => 'index';

websocket '/echo' => sub {
  my $c = shift;
  $c->app->log->debug('WebSocket opened');

  $c->inactivity_timeout(300);

  my $msg1 = `date`;
  $c->send($msg1);

  $c->on(finish => sub {
    my ($c, $code, $reason) = @_;
    $c->app->log->debug("WebSocket closed with status $code");
  });
};
app->start;

__DATA__

@@ index.html.ep
<!DOCTYPE html>
<html>
  <head><title>Test</title></head>
  <body>
    <script>
      var ws = new WebSocket('<%= url_for('echo')->to_abs %>');
      ws.onmessage = function(event) {
        document.getElementById("dateTime").innerHTML = event.data;
      };
    </script>

<h1 id="dateTime"></h1>
  </body>
</html>

Thanks like always.

How to check the DB every seconds or every few seconds and send that data via WS? copy/paste the example I linked ?:) oh right, its full of stuff copy/paste the example you already had in the beginning? Yeah, that sounds good, copy/paste the example you already had in Mojolicious Websocket example, the one trippledubs said worked Also see localtime/gmtime	[reply]

OK, I am learning that stuff. Here is a solution for my problem. Script runs every second and sends data ( current time in this example) via websocket. Here is the code: #!/usr/bin/env perl use warnings; use strict; use Mojolicious::Lite; get '/' => 'index'; websocket '/echo' => sub { my $c = shift; $c->app->log->debug('WebSocket opened'); $c->inactivity_timeout(300); my $id = Mojo::IOLoop->recurring(1 => sub { my $msg1 = `date`; $c->send($msg1); }); $c->on(finish => sub { my ($c, $code, $reason) = @_; $c->on(finish => sub { Mojo::IOLoop->remove($id) }); $c->app->log->debug("WebSocket closed with status $code"); }); }; app->start; __DATA__ @@ index.html.ep <!DOCTYPE html> <html> <head><title>Test</title></head> <body> <script> var ws = new WebSocket('<%= url_for('echo')->to_abs %>'); ws.onmessage = function(event) { document.getElementById("dateTime").innerHTML = event.data; }; </script> <h1 id="dateTime"></h1> </body> </html> [download] Thanks for help.
