Register for the Mini Program

Each Mini Program needs to register the Mini Program instance in app.js using the App constructor, bind the lifecycle callback function and mount the properties on the instance.

Use the getApp method to get an app instance.

App({
  globalData: {
    text: 'Hello Zepp OS'
  },
  onCreate() {
    console.log('onCreate')
    console.log(this.globalData.text)
  },
  onDestroy() {
    console.log('onDestroy')
  }
})

const app = getApp()
console.log(app._options.globalData.text)
