kaaya

Still under development, dont use except for testing.

Kaaya

Kaaya is a delightful javascript library which target on state management and data synchronization between Applications.

• Support different data structure (and their usual format):
  • Key Value: Often used to store configuration (.ini, .yaml, .json)
  • Table: Data grid like excel (.csv, .yaml, .json)
  • or plain JS object to store your own data
• Watch for data modification (mutation)
• Keep an history of mutation and allow to replay them on other object
• Allow to undo/redo modification
• Keep mutation as plain JS object (serializable)

Usage

Basic Store Creation

import kaaya from "kaaya"

// create a new store with custom data
var store = kaaya.createKeyStore({ a: 1, b: 2 })
store.data.a = 5
store.data.a = 10
// so far everything looks normal: { a: 10, b: 2 }

History Management

// let's play with the history
store.undo()
store.data // { a: 5, b: 2 }

store.undo()
store.data // { a: 1, b: 2 }

store.redo()
store.data // { a: 5, b: 2 }

Synchronization with other store

• only the history of mutation is send (modification)
• can be done over network, file, events, ...

// create other store and sync them with our first one data
var client1 = kaaya.createKeyStore({ a: 0, b: 6 })
client1.sync(store.history)
client1.data // <= { a: 5, b: 6 }

var client2 = kaaya.createKeyStore({ a: 0, b: 8 })
client2.sync(store.history)
client2.data // <= { a: 5, b: 8 }

// and now let's make a change and progate it
store.data.a += 10
client1.sync(store.history)

client1.data // { a: 15, b: 6 } properly sync :)
client2.data // { a: 5, b: 8 } not sync yet
