Loginmanager

Often you need to authenicate a user in a pwa. The loginmanager should help you to store the logindata in the localstorage and listen to changes.

The manager provides

• listeners for
  • the username input
  • the password input
• a login function (stores logindata in localstorage)
• a logoutfunction (removes the logindata from localstorage)
• reactive access to the logindata

const {
  user, // access username
  password, // access password
  listenUserInput, // listener for a textfield that emit llChange events
  listenPasswordInput, // listener for a textfield that emit llChange events
  login, // write logindata input to localstorage
  logout // remove logindata from localstorage
} = loginManager();
