sieds - Simple Immutable Events Driven Store

Simple storage for blazing fast development.

API

set()  
get()  
addListener()  
removeListener() 

set(value {Object})

Replace current state with obj.

set({users: ['Tom', 'Katy']}

set(key {String}, value {Mixed})

Replace property with provided value.

set('users', ['Tom', 'Katy'])  
set("users[13]", 'Gordon')  

get()

Returns current state

get(key {String})

Returns current value of property.

get('users[10]')

addListener(key {String}, listener {Function})

Adds listener for specific keys on set function - not on data data change.

addListener('users', () => {doSomething()});

removeListener(key {String})

Removes all listeners for specific key.

removeListener(listener {Function})

Removes provided function form any listning.

removeListener(key {String}, listener {Function})

Removes provided function form any listning on specific key.

Example

var SimpleStore = require("simple-store"),  
    store = new SimpleStore({numbers: ['1', '2', '3']}),  
    state = store.get();  
state.numbers[0] = '8';          // { numbers: [ '8', '2', '3' ] }  
store.get();                     // { numbers: [ '1', '2', '3' ] }  
store.set('numbers[0]', '0'));   // { numbers: [ '0', '2', '3' ] }

store.addListener('numbers[1]', (value) => {console.log("second number:", value)});  
store.set('numbers[1]', 6) // "second number: 6"

Pitfalls

If you are listening on nested event like users.europe.spain[34] you can overlook change in this field, because it could have place during set("users.europe.spain", [...]").
You are listening on set() first argument - key, not on actual data change.
