Vuex store:

• maintains a list of preferences
• has a USER_PREFERENCES_INIT action initializing all values
• has a USER_PREFERENCE_SET action that sets an individual preference value
• preferences is part of the user module state, a map of preference keys to values

DispatchingUserPreferenceRepository

• maintains a mapping of preferences to data sources and their configuration
  • preferences are identified by a name
  • preference persistence can be configured: currently the only way of doing so is via cookie
  • exposes method(s) used by vuex user preference store actions
  • is used during application initialization to set the vuex state accordingly
• cookie for our feature "wikibase-no-anonymouseditwarning"

Info:

• mw.cookie is an existing service to set and get cookies
• the current properties of the user state (name, primaryLanguage, secondaryLanguages) are not part of the preferences

We imagine something like the following to be the mapping of the DispatchingUserPreferenceRepository:

{
  'ignoreAnonWarning': new CookieUserPreferenceRepository( { ttl: 5000, cookieName: 'anon-warning-pref' }),
  'licenceWarning': new FallbackUserPreferenceRepository( new CookieUserPreferenceRepository( ... ), new MWUserSettingPreferenceRepository( ... ) ),
  ...
}
