Snippets

This page documents simple code snippets which augment or modify basic gun functionality.

Strip metadata from returned nodes

.live() (to replace .on())

Add the following prior to instantiating Gun:

Gun.chain.live = function(cb, opt){ 
  return this.on(function(val, field){ 
    delete val._; 
    cb.call(this, val, field); 
  }, opt); 
}

Instead of using .on(), use .live().
For example,

// subscribe to changes to my player bucket
playerNamesDB.on(function(data){

would be:

// subscribe to changes to my player bucket
playerNamesDB.live(function(data){

.value() (to replace .val())

Add the following prior to instantiating Gun:

Gun.chain.value = function(cb, opt){
  return this.val(function(val, field){
    delete val._;
    cb.call(this, val, field);
  }, opt);
}

Then, instead of using .val(), use .value().
For example,

// subscribe to changes to my player bucket
playerNamesDB.val(function(data){

would be:

// subscribe to changes to my player bucket
playerNamesDB.value(function(data){
