config-cache NPM version Build Status

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:

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

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

Example

var config = new Config();

.mixin

Static method for mixing Config prototype properties onto obj.

Params

Example

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

.set

Assign value to key or return the value of key.

Params

Example

config.set(key, value);

.get

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

Params

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

Example

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

.union

Add values to an array on the cache.

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:

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);

Visit the [expander] docs for more info.
