Datastore component is a single wrapper for your models and collections.
Some front end framework provide collections which are basically ordered sets of models (or arrays of objects) with no extra features. Datastore removes this overhead and helps you focus on your data instead of maintaining something useless.
Datastore contains your data and all the logic surrounding it such as formatters, access control, computed properties, reset, local storage and can be easily extended with its middleware engine.
component:
$ component install bredele/datastore
nodejs:
$ npm install datastore
bower(berk!):
$ bower install datastore-js
Datastore supports all mainstream browsers from IE8+. Supports IE7 with JSON polyfill.
Create a new store with the given data
(Object or Array).
var Store = require('datastore');
var users = new Store([{
name : 'eric'
},{
name : 'olivier'
}]);
Set an attribute name
with data object.
object store:
store.set('nickname','bredele');
array store:
store.set(0,{
name : 'amy'
});
Emits change
event with name, value, previous value
.
Emits change name
event with value, previous value
.
Or update a store with an object of same type:
object store:
store.set({
nickname: 'olivier',
lastname: 'wietrich'
});
array store:
//update 0
store.set([{
name: 'olivier',
github: 'bredele'
}]);
Get an attribute name
.
object store:
store.get('nickname');
array store:
store.get(0);
Delete a store attribute.
store.del('nickname');
Emits deleted
event with name
.
Emits deleted name
event.
Listen events on Store.
store.on('change', function(name, val, previous) {
...
});
Loop over the store data (use looping underneath).
store.loop(function(key, value) {
// do something
});
Compute store properties into a new property.
store.compute('id', function(){
return this.nickname + this.firstname;
});
Compute listen for changes on the computed properties and update automatically the new property.
Format an attribute output in Store.
store.format('nickname', function(val) {
return 'hello ' + val;
});
store.get('nickname'); //hello bredele
Pipe two stores.
//update child with store
store.pipe(child);
store.set('name', 'olivier');
child.get('name'); //olivier
Listen for changes and update both stores.
Reset store with data
(Object or Array).
store.reset([]);
Emits change
and/or deleted
events.
Synchronize store with local storage.
store.local('mystore'); //reset with localstorage
...
store.local('mystore', true); //save in localstorage
Use middleware to extend store.
store.use(function(obj) {
obj.save = function() {
//send to server
};
});
...
store.save();
See plugins
Here's a list of availaible plugins:
to get real time updates from a store in server side.
store.use(mirror('mychannel'));
store.set('hello', 'world');
to access nested data easily:
store.path('country.canada'); //get
store.path('country.canada.city', 'calgary');//set
to create template engines on both client/server sides:
store.filter('upper', function(str) {
return str.toUpperCase();
});
store.supplant('my name is {{name} | upper}');
to queue events.
store.queue('hello', 'world');
store.on('hello', function(val) {
//world
});
