  1. Solution

  • ABP’s Idle Session Timeout feature already works across multiple tabs of the same browser profile. It uses browser storage and a single activity monitor to keep all tabs in sync: user activity in any tab resets the idle timer, and when the warning/timeout is reached, all tabs react consistently.

  • To enable and configure it in Angular (v9.1.1):

    1. Ensure the Account Module is added on the backend and the Idle Session Timeout setting is enabled.
    2. Configure settings (host or tenant) in Settings > Account > Idle Session Timeout:
       • Enable Idle Session Timeout
       • Idle Time (minutes)
       • Show Warning Before (seconds)
    3. No extra Angular code is needed for multi-tab handling. The module’s built-in logic listens to user activity events (mouse, keyboard, click, etc.) and coordinates via storage so that all tabs share the same idle state.

  • If you want to customize behavior:

    • You can change thresholds or disable the feature per tenant/host from settings.
    • If you need to completely disable the feature for all users, set it off in Settings or override/hide the related setting UI (Angular) as a customization.

  Hi,

  The feature does not works for multiple tabs I have tested it. please let me know what's the solution for this.

  1. Solution

  • Current behavior (ABP v9.1.1, Angular): Idle Session Timeout works per-tab. The built-in Account Idle Session Timeout feature does not synchronize timers across multiple open tabs/windows by default. Each tab runs its own activity watcher and countdown. This is why you observe inconsistent behavior across tabs.

  • Implement multi‑tab sync (Angular) using storage events:

    • Goal: when user activity happens in any tab, reset the idle timer in all tabs; when warning/timeout occurs in one tab, all tabs show the same warning/perform logout.
    • Approach: broadcast activity and timer-state via localStorage and subscribe to the storage event in every tab.

    Example implementation outline:

    1. Create a small cross-tab channel

  // src/app/core/idle-sync.service.ts
    import { Injectable, NgZone } from '@angular/core';
  
    const CHANNEL_KEY = 'abp-idle-sync';
    type IdleSyncMessage =
      | { t: 'activity'; ts: number }
      | { t: 'show-warning'; deadline: number }
      | { t: 'cancel-warning' }
      | { t: 'timeout' };
  
    @Injectable({ providedIn: 'root' })
    export class IdleSyncService {
      constructor(private zone: NgZone) {
        window.addEventListener('storage', (e) => {
          if (e.key !== CHANNEL_KEY || !e.newValue) return;
          const msg = JSON.parse(e.newValue) as IdleSyncMessage;
          this.zone.run(() => this.onMessage?.(msg));
        });
      }
  
      onMessage?: (msg: IdleSyncMessage) => void;
  
      notify(msg: IdleSyncMessage) {
        // write-then-remove to trigger storage event in other tabs
        localStorage.setItem(CHANNEL_KEY, JSON.stringify(msg));
        localStorage.removeItem(CHANNEL_KEY);
      }
    }
  

  2. Wire it to ABP’s idle feature hooks (Angular):

  • In your app’s root component (or a dedicated initializer), listen to user activity and dispatch “activity” messages.
  • Hook into the idle warning display/hide and timeout actions to broadcast “show-warning”, “cancel-warning”, and “timeout”. Also react to incoming messages by invoking the same UI actions locally (so all tabs stay in sync).

  Example:

  // src/app/app.component.ts
    import { Component, HostListener, OnInit } from '@angular/core';
    import { IdleSyncService } from './core/idle-sync.service';
    import { AccountIdleSessionTimeoutService } from '@abp/ng.account/config'; // service used internally by ABP Account Angular UI
  
    @Component({ selector: 'app-root', template: '<router-outlet></router-outlet>' })
    export class AppComponent implements OnInit {
      constructor(
        private idleSync: IdleSyncService,
        private idleService: AccountIdleSessionTimeoutService
      ) {}
  
      ngOnInit() {
        // 1) When local idle feature is about to show warning, broadcast to others
        this.idleService.onShowWarning$.subscribe((deadlineUtcMs) => {
          this.idleSync.notify({ t: 'show-warning', deadline: deadlineUtcMs });
        });
  
        // 2) When local warning is cancelled (user activity), broadcast
        this.idleService.onCancelWarning$.subscribe(() => {
          this.idleSync.notify({ t: 'cancel-warning' });
        });
  
        // 3) When local timeout happens (logout), broadcast
        this.idleService.onTimeout$.subscribe(() => {
          this.idleSync.notify({ t: 'timeout' });
        });
  
        // 4) React to messages from other tabs
        this.idleSync.onMessage = (msg) => {
          switch (msg.t) {
            case 'activity':
              this.idleService.resetTimerFromExternalActivity(); // custom helper; see below
              break;
            case 'show-warning':
              this.idleService.showWarningExternally(msg.deadline);
              break;
            case 'cancel-warning':
              this.idleService.cancelWarningExternally();
              break;
            case 'timeout':
              this.idleService.triggerTimeoutExternally();
              break;
          }
        };
      }
  
      // Broadcast user activity from this tab
      @HostListener('document:mousemove')
      @HostListener('document:keydown')
      @HostListener('document:click')
      onActivity() {
        this.idleSync.notify({ t: 'activity', ts: Date.now() });
      }
    }
  

  3. Expose minimal helpers on top of ABP’s idle Angular service:

  • If the ABP Angular Account idle service you use doesn’t expose such methods, wrap/extend it where you already subscribe to its events (warning start/cancel, timeout). The idea is to:

    • Keep one source of truth for the timer per tab (the existing ABP idle service),
    • On incoming “activity” message, simply call the same “reset” logic you use when the user moves mouse/presses key,
    • On “show-warning/cancel/timeout” messages, call the same internal methods you call locally to show/cancel the warning modal or sign out. If needed, implement a thin facade service that calls to the ABP components or dispatches the same RxJS streams they use.

  • Notes:

    • Use localStorage, not sessionStorage. The browser fires “storage” events only across tabs for localStorage.
    • Include a debounce/throttle if you want to reduce the activity message rate.
    • If you cannot call internal methods of the ABP idle service, mirror the behavior by:
      • Stopping/starting your local countdown timer when “activity” arrives,
      • Opening/closing the same warning modal component with the same translations and deadline,
      • Calling the existing sign-out flow on “timeout” (e.g., AuthService.logout()).

  hi

  What is your UI page?

  The feature does not works for multiple tabs I have tested it.

  Can you share details? What are steps to reproduce?

  Thanks.
