ng-vault v0.4.0

ng-vault

=========== ng-vault wraps over angular's $cacheFactory to provide few nifty ways to save and retrieve data. ng-vault contains these two parts:

• $vault factory which has methods for storing and retrieving data.
• $vaultConfigProvider for configuring the behaviour of $vault factory.

Installation

###Via yarn or npm:

# yarn (recommended)
$ yarn add ng-vault

#npm
$ npm install ng-vault --save

Then use it as:

var angular = require('angular');
angular.module('mainApp', [ require('ng-vault') ]);

###Via bower:

$ bower install ng-augment-native-scroll --save

Then use it as:

var angular = require('angular');
var ngAugmentNativeScroll = require('./bower_components/ng-vault/src');

angular.module('mainApp', ['ng-vault']);

You can also include it in the old fashion way as:

<script src="/bower_components/ng-vault/dist/ng-vault.js"></script>
<!-- or -->
<script src="/bower_components/ng-vault/dist/ng-vault.min.js"></script>

Provider Configuration

Normally we may not need to configure the behaviour of $vault. Still he is an example of how we can do it:

angular.module('mainApp')
    .config(function ($vaultConfigProvider) {
        $vaultConfigProvider.set({
            id: 'starwars',
            limitTypes: {
                isArray: true,
                isDate: true,
                isFunction: true,
                isNumber: true,
                isObject: true,
                isString: true
            },
            putUptoMins: 5
        });
    });

id - type:String - default:$vault

The unique name with which the internal store of ng-vault will be created.

limitTypes - type:Array - default:[]

By default we can save any type of data into $cacheFactory, $vault can be configured to accept only the configured types. This can be help control $vault usage. Skip this to allow $vault to save all type of data. The key names in options, isArray, isDate... are the same methods available on angular. Internally $vault uses angular.<key name> to check types. Using plain typeof type === typeof vaule can produce inconsistent results.

putUpto - type:Number - default:3

Using when we put some data in, it will be retained as long as it's not removed. But sometime we may want to retain data only for a short while. It should be removed once the time is up. We can use putUpto method to put data with an additional mins argument. Here putUptoMins can be set as the default value to be used, in case putUpto is not provided with an additional mins argument.

Usage

Now we can inject $vault into any other part of our code to put and get values. Here are the list of all methods that $vault packs:

put

To put data in, only defined data. It will check the data type with the set limitTypes. If it passed it will saved. If not it will display a console warn.

$vault.put('episode-4', 'A New Hope');

putUpto

Put for certain time, after which it will be removed

$vault.putUpto('episode-5', 'The Empire Strikes Back', 5);

// after 5 mins (5 * 1000 * 60)
$vault.has('episode-5');
// false

putOnce

Put value and remove once it's retrieved.

$vault.putOnce('episode-6', 'Return of the Jedi');

$vault.get('episode-6');
// Return of the Jedi

$vault.has('episode-6');
// false

get

Get a stored data. If not found it will return undefined.

$vault.get('episode-2');
// Attack of the Clones

has

Check if a particular key exist. Returns true or false.

$vault.has('episode-3');
// true

remove

Remove a key from $vault

$vault.remove('episode-1');

info

Retrieve information regarding the store - id and size

$vault.info();
// {
//     id: 'starwars',
//     size: 5
// }

removeAll

Remove everything from $vault

$vault.removeAll();

Testing and code-coverage

#Future Data is still stored in memory. Add methods to save them to localStorage or indexedDB.
