A super simple package to allow you to set watchers/listeners on your javascript variables.
Useful mostly for debugging when you aren't sure where a variable is being set/modified.
Just slap a watcher on it:
var watch = require(object-watcher).watch;
var data = {
quantity: 0
, products: []
}
, watcher = function(propertyName, oldValue, newValue){
console.log("Variable Changed!");
console.log(propertyName, oldValue, newValue);
};
watch(data, 'quantity', watcher);
watch(data, 'products', watcher);
data.quantity = 8
// Variable Changed!
A slightly more compact version:
watch(data, 'quantity', function(propertyName, oldValue, newValue){
console.log("Variable Changed!");
console.log(propertyName, oldValue, newValue);
});
