simple-basket

A simple javascript basket for values.

Store values and objects in an array in memory.

Dependencies

lodash version: ~3.9.3

If you want to use the storage feature included that permits a basket to be saved in browser databases with the localforage package, you'll need:

• es6-promise version ~2.2.0
• localforage version ~1.2.3
• localforage-sessionstoragewrapper version ~1.0.1

(the package dist includes a bundle file that ships all these 3 dependencies)

How to use

• Install with Bower

$ bower install simple-basket

• Install with npm

$ npm install simple-basket

• or get the javascript in dist folder: simplebasket.js

Use

Create a basket:

//on browser
var basket = window.simplebasket.create();

//on node
var basket = require('simple-basket').create();

Add items:

//add array
var aitems = [1, 2, 3, 4, 5, {'id': 1, name: 'john'}, {'id': 2, name: 'john'}];
basket.add(aitems);

//add list of items (
basket.add(1, 2, 3, 4, 5, {'id': 1, name: 'john'}, {'id': 2, name: 'john'});

Get items

basket.getall(); //[1, 2, 3, 4, 5, {'id': 1, name: 'john'}, {'id': 2, name: 'john'}]

Find items

basket.find({key: 'id', value: '2'}) //[{'id': 2, name: 'john'}]

basket.find({key: 'name', value: 'john'}) //[{'id': 1, name: 'john'}, {'id': 2, name: 'john'}]

simplebasket Interface

• create() - Initialize a new Basket

Extending the basket

• plug() - permits plugging a plugin-wrapper
• unplug() - unplugg a plugin-wrapper
• getBasePluginWrapper() - just to get the plugin base object for use as wrapper
• getBasePlugin() - just to get the plugin base object for use without wrapper (direct call to driver)
• Basket - get the Basket constructor

Basket Interface

• add() - Add one or more items to basket
• set() - Sets the basket cloning from an array of values
• getClone() - Returns all items in basket (clone)
• remove() - Remove an item(s) by a reference a key/value pair
• removeAt() - Remove one item by position
• removeAll() - Removes all items in the basket (Clear the basket)
• iterate() - Iterate the basket calling a function for each item
• count() - Returns the number of items in the basket
• find() - Find values in basket

The Basket interface is extended with:

• implement() - allows an instance Basket to implement a driver for the plugin-wrapper interface
• dispose() - removes from an instance Basket a driver implementation for the plugin-wrapper interface

The package comes with a storage.js wrapper and a localforageDriver.js that permits a basket to be saved in browser databases with the localforage package.

Using the storage wrapper

Example with the localforageDriver

option 1 - using the complete bundle (easy)

Include File: dist/plugins/storage/storage-localforage.js This file include all dependencies needed:

• the es6-promise polyfill (as the wrapper relies on promises) for browsers that don't support it - is used the same polyfill that ships with localforage;
• the localforage package
• the localforage-sessionstoragewrapper package for session storage

option 2 - install dependencies

bower install localforage#1.2.3

bower install localforage-sessionstoragewrapper#1.0.1

Include the files:

• dist/plugins/storage/storage.js
• dist/plugins/storage/drivers/localforageDriver.js

var basket, lfDriver;

basket = window.simplebasket.create();
basket.add({key: 1}, {key: 2}, {key: 3});

window.localforageDriver
  .create(window.localforageDriver.STORAGE.LOCALSTORAGE, {name: 'app', storeName: 'store', key: 'basket'})
  .then(function( value ) {
  
    lfDriver = value;
    basket.implement(basket.ISTORAGE, lfDriver);
    
    //to save the basket
    basket.save()
      .then(function( data ) {
        //basket was saved to storage
      })
      .catch(function( error ) {
        //error
      });
    
    //...
    
    //to load the basket from storage:
    basket.load()
      .then(function( data ) {
        //data loaded from storage to basket
      })
      .catch(function( error ) {
        //error
      });
});
