missing exec:ZeroConf.watch

[drasko]

Hi, I am trying ZeroConf plugin with simple lines:

onDeviceReady: function() {
        app.receivedEvent('deviceready');

        ZeroConf.watch('_http._tcp.local.', function(result) {
           // do something with the result
           console.log("RESULT: " + result);
        });

        ZeroConf.list('_http._tcp.local.', 1000, function(resultArray) {
          alert("Scanned " + resultArray[0] + " code: " + resultArray[1]);
        }, function(error) {
          alert("Failed: " + error);
        });
    },

What I am getting is something like ZeroConf can not be found by Cordova:

Just to make it sure, the plugin is installed using the cordova-cli tool, right?

Can you also post some details about your environment (e.g. Cordova version). Thanks!

[drasko]

Yes, using Cordova CLI.

I am using most recent Cordova, freshly installed with npm -g install cordova. I guess it is version v4.2.0.

Are you sure that ZeroConf is included right after installation with CLI? I never wrote something like require('ZeroConf'), I just start using it straight away, as you suggested. Here: https://github.com/phonegap/phonegap-plugins/wiki/Defining-Your-Cordova-Plugin-As-A-Cordova-Module I can see that some require is needed. Is this the case for ZeroConf also?

I have tested the plugin only with Cordova 3.x. Have to check if something changed since

Hello, actually this code:

onDeviceReady: function() {
        app.receivedEvent('deviceready');

        ZeroConf.watch('_http._tcp.local.', function(result) {
           // do something with the result
           console.log("Service name: " + result.service.name);
        });
    }

works fine on device, Nexus5 phone, built with Cordova v4.2.0

ripple emulate however expects to give it JSON structure on the input, in the prompt form. I copy-pasted JSON example from your README.md and it worked.

I had one error before, like this: http://stackoverflow.com/questions/26015733/uncaught-syntaxerror-unexpected-token-o-json-parse, trying to JSON.parse(result), not understanding that it was already a parsed object.

You can close the issue.

Glad to see that you made it work.

On the JSON input, the communication between the native side and JavaScript is implemented using strings. So, it you pass objects they have to be serialized to JSON.
