State: Settings

State is required for app settings. This state will require actions to update the current settings, a state interface describing the structure of the state, a reducer to handle changes to settings, and selectors to retrieve the current settings.

Actions should be created with the NgRx createAction utility function.
Selectors should be created with the NgRx createSelector utility function.
Reducers should be created with the NgRx createReducer utility function.

• Note: For AOT compilation purposes, the created reducer must be wrapped in a static function (see below)

Actions:

• filtersChanged (event)
  • Parameters:
    • filters: EventFilter
• sortChanged: (event)
  • Parameters:
    • sort: ListSort
• formatChanged: (event)
  • Parameters:
    • format: ListFormat
• mapLayersChanged: (event)
  • Parameters:
    • layers: MapLayers
• timeZoneChanged: (event)
  • Parameters:
    • timeZone: TimeZone

State Interface:

• Should be mapped in app state interface in state/index.ts
• Name: ISettingsState
• Properties:
  • settings: Settings
    • Optional

Reducer:

• Should handle the action defined above
• Should be mapped into reducer map in state/index.ts
• Must be wrapped in an AOT compatible function named for the state (see State: Events)

Selectors:

• autoUpdate: Retrieve autoUpdate flag from state
• currentFilters: Retrieve filter from state
• currentSort: Retrieve listSort from state
• currentFormat: Retrieve listFormat from state
• currentMapLayers: Retrieve mapLayers from state
• currentTimeZone: Retrieve timeZone from state
