Current State
A node module that provides a mutable object that stores state. Once the underyling object is mutated through the interface a changed event is fired for reactive application design. It unsafely provides the underlying data object using the get() command, and re-uses the passed in object. The changed event provides the current and previous object. This module was built in a way to limit memory allocation and garbage collection.
Usage
var CurrentState = require('current-state')
var state = CurrentState({
character : "Link",
game : "Ocarina of Time"
})
var handleChange = function( current, previous ) {
console.log( "You are playing", current.game )
console.log( "Your character is:", state.get('character') )
console.log( "Your preivous character was:", previous.character )
console.log( "Current state:", state.get() )
}
state.onChange(handleChange)
state.set("character", "Zelda")
state.set({game: "Majora's Mask"})
state.offChange(handleChange)
Interface
state.get()
state.get("key")
state.set("key", "value")
state.set(object)
state.set("key", "value", true) //Set silently
state.set(object, true) //Set silently
state.onChange(function( current, previous ) { ... })
state.offChange(function( current, previous ) { ... })
