Google Assistant Integrated with YodaOS
What's new parts?
Next?

Demo:
1. 喚醒音箱
2. 資料送到 Google
3. YodaOS 處理應用層

>> Yoda's service based on google assistant
## new part
- application framework
- Voice interface driver integrates voice service (ex.google assistant alexa and etc)
- 碎片化嚴重
- 上傳格式不統一
- YodaOS 設備端應用開發統一，兼容不同雲端
- development toolkit(based on android adb)

## Brief History
- Linux Kernal
- HAL 硬體抽象化
- System Framework 藍芽等硬體
- Specific Voice Runtime
- 兼容不同語音服務
- Specific Voice Service

## Driver
- 轉換其他服務的 API
- 提供一個統一 API
- 實作 callback 執行你要的功能
- 雲端指令轉成 local URL
- local events to cloud

## yoda's messaging
- multiplex messaging
- URL 用 router 概念去撰寫
- yoda-app://setup/init
- yodaapp://cloud-player/play
- yoda-app://bluetooth/open?discovery=1
- yoda-app://volume/set?value=90
- Event
- ```javascript
var target = new EventTarget('yoda.apps.cloud-player')
target.on('tt.open', /*...*/)

    - Function
        - ```javascript
            var player = new FunctionTarget('yodas.on')
            player.on('')

- Framework 與 Interface driver 用上述的 Yoda Message 來溝通

## Fauna Framework
>
#### Client
- self-discovering YodaOS API
- 其他的可根據協議做出
#### Runtime
- hive: 加快應用啟動
- 獨立的 process
## YodaOS App
- Library
- @yodaos/application
- speech-

## YodaOS next
- IoT 硬體不一樣，兼容超難

## requirement
- nodejs core partially
- complete N-API

## awesome

## yoda.js
-application framework in runtime enviromnment
