Register to set up the application

Setting up the application requires registering an instance using the AppSettingsPage constructor, binding the lifecycle callback function.

Currently there is only one build lifecycle.

app.js

AppSettingsPage({
  build(props) {}
})

Expand on the type of this constructor：

interface Props {
  settings: Option
  settingsStorage: SettingsStorage
}

interface Option {
  build: (props: Props) => RenderFunc
  [propName: string]
}

interface AppSettingsPage {
  (option: Option): void
}

In short, props.settings is the option in AppSettingsPage(option), props.settingsStorage is the body of the SettingsStorage API call, refer to the API chapter for how to use it.

RenderFunc is the UI rendering function, all the UI component functions return value is RenderFunc, about UI components, refer to Introduction to the use of UI components.
