Can the state of an AngularJS app be preserved using Angular local storage? I am developing an information-based app with a substantial amount of content, and I want to save the user's current "location" so that when they reopen the app later, it opens at the saved point.
I have been exploring cookies and local storage, searching for related topics, but I have not found any resources that specifically address this issue in AngularJS, only in jQuery.
Have you managed to resolve this particular issue? I was able to successfully address it by implementing the following three steps:
During the angular config phase, I integrated a $transitions.onSuccess hook within my code to intercept permissions. This hook listens for all transition successes and saves the current state name, excluding 'signin' and 'signout' states.
$transitions.onSuccess('*', function(trans) {
var currentState = trans.router.stateService.current.name;
if (currentState !== 'signin' &&
currentState !== 'signout') {
$localStorage.storeState(trans.router.stateService.current.name);
}
});
Within the signin/authentication process (or any relevant area where user authentication is checked), I ensure that the user is redirected to a specific state and then back to the previous state.
var previousState = $localStorage.getState() || Authentication.redirectState;
if (Authentication.isAuthenticated()) $state.go(previousState);
As part of the storage factory functionality, I incorporated a function to delete the stored state upon signout.
