Mobx Persist

$ npm install mobx-persist --save

Usage

import { observable } from 'mobx'
import { create, persist } from 'mobx-persist'

class SomeItem {
    @persist @observable  name = 'some'
    @persist @observable count = 0
}

class SomeStore {
    @persist('object') @observable         obj = { a: 1, b: 2 }
    @persist('map')    @observable   stringMap = observable.map({})
    @persist('list')   @observable     numList = [1,2,3,4]
    @persist('object', SomeItem) @observable s = new SomeItem
    @persist('map', SomeItem)    @observable m = observable.map({})
    @persist('list', SomeItem)   @observable l = []
}

const hydrate = create({
    storage: localForage,   // or AsyncStorage in react-native.
                            // default: localStorage
    jsonify: false  // if you use AsyncStorage, here shoud be true
                    // default: true
})

// create the state
export const someStore = new SomeStore()

hydrate('some', someStore)
    // post hydration
    .then(() =&gt; console.log('some hydrated'))

without decorators

const data = observable({
    title: 'no decorator',
    someObject: {
        a: 1,
        b: 'b',
    },
    someArray: [{
        c: 1,
        d: 'd'
    }]
})
const schema = {
    title: true,
    someObject: {
        type: 'object',
        schema: {
            a: true,
            b: true
        }
    },
    someArray: {
        type: 'list',
        schema: {
            c: true,
            d: true
        }
    }
}
export const someStore = persist(schema)(data)
hydrate('some', state)
    .then(() =&gt; console.log('some hydrated'))

with initial state

const initialState = window.__STATE__.some || {
    obj: { a: 2, b: 1 }
}
export const someStore = new SomeStore()

hydrate('some', someStore, initialState)
    .then(() =&gt; console.log('some hydrated'))

re-hydration

const result = hydrate('some', someStore, initialState)
const rehydrate = result.rehydrate
result.then(() =&gt; console.log('some hydrated'))

setTimeout(() =&gt; {
    rehydrate().then(() =&gt; console.log('rehydrated'))
}, 3000)

API

`persist(schema)(object)`

arguments
- schema string/object Describes the type of data you are planning to persist. Not needed for JS primitive types. Options: 'object' | 'list' | 'map' or a structured schema object.
- observable any The observable that you are persisting.
returns a persistence-enabled version of observable

`create(config)`

arguments
- config object Describes the storage container you want your data to reside in.
  - storage localForage/AsyncStorage/localStorage localForage-style storage API. localStorage for Web (default), AsyncStorage for React Native
  - jsonify bool Enables serialization as JSON
  - debounce number Debounce interval applied to storage calls (in miliseconds, default 0).
returns
- hydrate function hydrate(key, store)
  - key string The key of your datastore that you want to hydrate from your persisted record.
  - store object The store in which that key resides.
  - returns IHydrateResult

interface `IHydrateResult`

extends Promise

methods
- rehydrate function
  - returns IHydrateResult
