Aware

Bindable key-value storage.

npm install aware --save
  • .on(key, handler) - listening for key changes
  • .off(key, handler) - unlistening key changes
  • .get(key, 'value') - getting key value
  • .set(key, 'value') - setting key value
  • .set({key: 'value'}) - bulk set keys on dictionary
var aware = require('aware');
 
var store = aware();
 
store.on('name', function(name){
  console.log(name);
}
 
store.set('name', 'bender'); // will fire handler above 
store.get('name'); // bender 
 
// since the property exists now, this handler will be fired right 
// away, and after that every time the value for 'name' changes 
var name_handler = function(name) {
  console.log(name);
};
store.on('name', name_handler);
 
store.set('name', 'bender'); // will fire nothing 
store.set('name', 'john'); // will fire callback again 
store.set('name', 'lecter'); // will fire callback again 
 
// unlistening 
store.off('name', name_handler);
 
store.set('name', 'peter'); // will fire nothing 
```
 
### With objects
 
````javascript
var store = aware({
  set_name: function(name){
    this.set('name', name);
  }
});
 
store.on('name', function(name){
  console.log('name changed', name);
});
 
store.set_name('name', 'bender');
function Store(){
  aware(this);
}
 
Store.prototype.set_name = function(name){
  this.set('name', name);
}
 
var store = new Store();
store.on('name', function(name){
  console.log('name changed', name);
});
 
store.set_name('name', 'bender');

Lets you compose keys bundling it based on values from one or more different keys.

var store = aware();
 
store.on('name', function(name){
  console.log('name changed', name);
});
 
store.set('name', '#{first-name} #{second-name}');
store.set('first-name', 'hannibal');
store.set('last-name', 'lecter');
