API

Container

A nested key-value store with path-based access:

let container = new Container()

// set nested values
container.set(['options', 'theme'], 'dark')
container.set(['options', 'lang'], 'uk')

// get nested values
container.get('options', 'theme')  // 'dark'
container.get('options')           // { theme: 'dark', lang: 'uk' }
container.get()                    // entire container

// check existence
container.has('options', 'theme')  // true
container.has('options', 'color')  // false

SimpleCache

Simplified Container with flat key-value interface:

let cache = new SimpleCache()

cache.set('key', result)
cache.has('key')          // true
cache.get('key')          // result

Settings

Container backed by localStorage. Loads on construction, merges stored values over defaults:

// load settings (merges localStorage data over defaults)
let settings = new Settings('my-script', {
  enabled: true,
  radius: 200
})

// read
settings.get('enabled')    // true
settings.get('radius')     // 200

// update
settings.set(['radius'], 500)

// save to localStorage (call before page unload)
settings.save()

With jQuery:

$(window).on('beforeunload', () => settings.save())

Tools

Static utility methods:

// deep merge objects (preserves nested structure)
let result = Tools.mergeDeep({}, defaults, overrides)

// check if value is a plain object
Tools.isObject({})     // true
Tools.isObject([])     // false
Tools.isObject(null)   // false
