Still under development, do not use except for testing

  • 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)
    • Entities: List of instantiated object
    • Files: File/Folder structure (like a file explorer)
    • 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)
  • Allow to regroup mutation as transaction (to give context about changes)
  • Allow to use async hook (for animation or UI interaction)

Usage

Basic Store Creation

import kaaya from "kaaya"
 
// create a new store with custom data
const 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
const client1 = kaaya.createKeyStore({ a: 0, b: 6 })
client1.sync(store.history)
client1.data // <= { a: 5, b: 6 }
 
const 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

And more ....


Development

Getting Started

If you want to take a look at the code or help, it's quite easy to get started

npm install
npm run dev

This will start a server on http://localhost:8080/ where you can test few samples with the current version

Tests

When you are done with your change, just make sure to run tests npm run test

Build

To make a build (generated in build/)

npm run build

Known Limitation

  • Some array function like .push or .slice cause the whole object to be mutated and not just the value being changed
  • Doesnt handle advance object like Set or Map
