database - Getting streaming data from gun -

on() supposed stream data path or key ¹. when put data on path, i'm not seeing updated stream.

var mydata = gun('https://gunjs.herokuapp.com/gun')              .get('example/demo/set'); mydata.on(); mydata.put({hello:'world'}); 

.on() asynchronous function, need update code this:

var mydata = gun('https://gunjs.herokuapp.com/gun')              .get('example/demo/set'); mydata.on(function(data){     console.log("update:", data); }); mydata.put({hello:'world'}); 

hope helps!

if new programming, "anonymous functions" (often times called callback) in above code can confusing. above code can rewritten this, has exact same behavior:

var mydata = gun('https://gunjs.herokuapp.com/gun')              .get('example/demo/set');  var cb = function(data){     console.log("update:", data); };  mydata.on(cb);  mydata.put({hello:'world'}); 

for debugging purposes, there .val() convenience function automatically log data you:

var mydata = gun('https://gunjs.herokuapp.com/gun')              .get('example/demo/set'); mydata.on().val() mydata.put({hello:'world'}); 

however intended one off purposes, not streaming. note, can pass .val(function(data){}) callback override default convenience logger.
