Justore

We don't need flux , just the store!

Installation

npm install justore --save

Basic Usage

var justore = require("justore");
var initData = {};
var store = new justore(initData,'Store Name');


//Write or change data to store, return a Promise
store.write('todos',['drink','cook']);

//Subscribe to change
let subscription = store.sub('todos.0',function(newVal,prevVal){
  store.read('todos') === newVal //true, 'drink'
});
//Remember to clean up
subscription.unsubscribe();

Advanced usage

• store.batchWrite([keyPaths], manipulateFunction); Batch write multiple data to the store, only emit if it's listed on the keyPaths

    store.batchWrite(['vtext', 'enable'], draft => {
      draft.vtext.i = 10
      draft.enable = true
      draft.pos = 12 // works, but no event emit
    });

• store.write(keyPath, data [,options])

  Write data to the store, return store

    store.write('todos',['drink','cook'],{
      //Boolean. If true, change the store without trigger any events
      mute:false
    });

• store.sub(keyPath[,onNext][,immediate])

  Subscribe to the store, if onNext is defined, return an Rx Subscription, else return an Rx stream

    store.sub('todos.1',function (newVal, oldVal) {
  	  //do tings
    });

• store.read(keyPath)

  Get value for attribute by passing the key.

    store.read("todos.0") //--> 'drink'

• store.delete(keyPath)

  Useful when you want to delete a root key and it's data

    store.delete("todos")
    store.report()  //--> {}

• store.report()

  return the full store data. You cannot manipulate it

• store.debugOn

  if a key in this array, will toggle JS breakpoints when writing that key

React Mixin helper

• store.createReactMixin(key)

  Return a mixin. Will call onStoreChange method on a React component when store change.

Auto unsubscibe

If the subscribed data has been deleted (not set to undefined), the subscription will unsubscribe automatically
