Vuex state synchronization between iframe/window

Your star is the greatest encouragement to me.

• support iframes/window sync
• initialization sync when iframe loaded
• configure the sync behavior for your specific needs

• Vue.js (v2.0.0+)
• Vuex (v2.1.0+)

Note window.postMessage has limition on message, works like JSON.parse() and JSON.stringfy().If you have trouble with it, configure a convert function in broadcast and transfer API.

• MDN window.postMessage
• MDN Structured_clone_algorithm

<script src="https://cdn.jsdelivr.net/npm/vuex-iframe-sync/dist/vuex-iframe-sync.umd.js"></script>

npm install vuex-iframe-sync --save

yarn add vuex-iframe-sync

• live example
• with webpack
• simple

// in parent's component with iframe
<iframe id="frameId1"/>
<iframe id="frameId2"/>

// in parent's store.js
import {broadcast} from 'vuex-iframe-sync'

export default new Vuex.store({
  // ...
  plugins: [
    broadcast('frameId1,frameId2')
  ]
})

// in iframe's store.js
import {transfer} from 'vuex-iframe-sync'

export default new Vuex.store({
  // same state and mutations with parent
  plugins: [
    transfer()
  ]
})

Send state changes payload to iframes through postMessage API while parent state change.

ids <String|Array>: frameIds split by ',' or [{id: iframeId, origin: iframeOrigin}...]

options : The following options can be provided to configure the parent behavior for your specific needs:

• convert <Function(payload)>: convert payload before pass to iframes.

Receive state changes from parent. Send state changes to parent while self state change.

options : The following options can be provided to configure the iframe behavior for your specific needs:

• created <Function(id, store, send)>: call after iframe created. id: iframeId、store: this.store、send<Function(type, payload)>：parent.$store.commit
• destroyed <Function(id, store, send)>: call after iframe destroyed. id: iframeId、store: this.store、send<Function(type, payload)>：parent.$store.commit
