config-cache

General purpose JavaScript object storage methods.

Breaking changes in 5.0!

Major breaking changes were made in 5.0!

In an effort to simplify the library, the following methods were removed:

clone: use clone-deep, example: var obj = cloneDeep(config.cache)
keys: use Object.keys(config.cache)
omit: use .del()
exists: use config.cache.hasOwnProperty() or has-value
has: use config.cache.hasownProperty() or has-value
hasOwn: use config.cache.hasOwnProperty() or has-value

The following data methods were also removed, use plasma-cacheif you need these methods:

data
process
plasma
extendData

Install

Install with npm

$ npm i config-cache --save

Usage

var Config = require('config-cache');
var config = new Config();

API

Config

Initialize a new Config, optionally passing an object to initialize with.

Params

cache {Object}

Example

var config = new Config();

.mixin

Static method for mixing Config prototype properties onto obj.

Params

obj {Object}
returns {Object}

Example

function App() {
  Config.call(this);
}
Config.mixin(App.prototype);

.set

Assign value to key or return the value of key.

Params

key {String}
value {*}
returns {Object} Config: to enable chaining

Example

config.set(key, value);

.get

Return the stored value of key. Dot notation may be used to get nested property values.

Params

key {*}
escape {Boolean}
returns {*}

Example

config.set('foo', 'bar');
config.get('foo');
// => "bar"

// also takes an array or list of property paths
config.set({data: {name: 'Jon'}})
config.get('data', 'name');
//=> 'Jon'

.constant

Create a constant (getter/setter) for setting and getting values on the given namespace or this.cache.

Params

key {String}
value {*}

Example

config.constant('site.title', 'Foo');

.union

Add values to an array on the cache.

returns {Object} Config: to enable chaining

Example

// config.cache['foo'] => ['a.hbs', 'b.hbs']
config
  .union('foo', ['b.hbs', 'c.hbs'], ['d.hbs']);
  .union('foo', ['e.hbs', 'f.hbs']);

// config.cache['foo'] => ['a.hbs', 'b.hbs', 'c.hbs', 'd.hbs', 'e.hbs', 'f.hbs']

.extend

Extend the cache with the given object. This method is chainable.

Or define the property to extend:

returns {Object} Config: to enable chaining

Examples

config
  .extend({foo: 'bar'}, {baz: 'quux'});
  .extend({fez: 'bang'});

config
  // extend `cache.a`
  .extend('a', {foo: 'bar'}, {baz: 'quux'})
  // extend `cache.b`
  .extend('b', {fez: 'bang'})
  // extend `cache.a.b.c`
  .extend('a.b.c', {fez: 'bang'});

.del

Remove keys from the cache. If no value is specified the entire cache is reset.

Example

config.del();

Usage Examples

.set

If expand: true is defined on the options, the value will be set using [expander].

Examples:

// as a key-value pair
config.set('a', {b: 'c'});

// or as an object
config.set({a: {b: 'c'}});

// chaining is possible
cache
  .set({a: {b: 'c'}})
  .set('d', 'e');

Expand template strings with expander:

config.set('a', {b: '${c}', c: 'd'}, true);
