Auto Logout

auto-logout.js

const store = require('store');

const MINUTES_UNITL_AUTO_LOGOUT = 5 // in mins
const CHECK_INTERVAL = 1000 // in ms
const STORE_KEY =  'lastAction';

class AutoLogoutService {

  get lastAction() {
    return parseInt(store.get(STORE_KEY));
  }
  set lastAction(value) {
    store.set(STORE_KEY, value);
  }

  constructor(authService) {
    this.auth = authService;
    this.check();
    this.initListener();
    this.initInterval();
  }

  initListener() {
    document.body.addEventListener('click', () => this.reset());
  }

  reset() {
    this.lastAction = Date.now();
  }

  initInterval() {
    setInterval(() => {
      this.check();
    }, CHECK_INTERVAL);
  }

  check() {
    const now = Date.now();
    const timeleft = this.lastAction + MINUTES_UNITL_AUTO_LOGOUT * 60 * 1000;
    const diff = timeleft - now;
    const isTimeout = diff < 0;

    if (isTimeout && this.auth.loggedIn) {
      this.auth.logout();
    }
  }
}

How can I consume this logout service in my angular app?

Sorry, I didn't get informed by github about the comments.

Consuming is easy: Just inject it into your AppComponent.

export class AppComponent {
  constructor(
    private autoLogout:AutoLogoutService
  ) { }
}
