Walkthrough

Adds an auto-join flow to MeetingJoinComponent with delayed execution, state signals, secure URL opening, and cleanup. Updates the template to conditionally display auto-join status, dynamic severity/icon, and testing identifiers. Routes all join actions through a secure opener. Implements OnDestroy to clear pending timeouts.

Changes

Cohort / File(s)	Summary of changes
Component logic: auto-join, signals, secure opener `apps/lfx-one/src/app/modules/meeting/meeting-join/meeting-join.component.ts`	Implements auto-join via reactive effect and 500ms timeout with guard state (`hasAutoJoined`), adds cleanup in `ngOnDestroy`, introduces UI signals (`messageSeverity`, `messageIcon`), adds `performAutoJoin`, `openMeetingSecurely`, and initializers, integrates with existing URL-building, and replaces direct `window.open` calls.
Template updates: conditional statuses and test ids `apps/lfx-one/src/app/modules/meeting/meeting-join/meeting-join.component.html`	Reorders conditionals to include `hasAutoJoined()` branch, switches to dynamic severity/icon helpers, adds `data-testid` attributes to status and join buttons, and aligns form-join button with new conditions.

apps/lfx-one/src/app/modules/meeting/meeting-join/meeting-join.component.ts (5)
73-73: LGTM! Timeout type improved.

The timeout property now uses ReturnType<typeof setTimeout> | null, which provides better type safety compared to any.

97-121: Verify the effect pattern with async signal writes.

The effect uses allowSignalWrites: true to schedule a timeout that later modifies signals. This pattern can potentially cause issues:

The effect re-runs whenever any tracked signal changes, which could lead to multiple timeouts being scheduled and cleared rapidly.

The timeout callback modifies hasAutoJoined, which could trigger the effect again, though the guard conditions should prevent this.

Please verify this approach doesn't cause any unexpected re-triggering or timing issues, especially in edge cases like rapid authentication state changes or when the user quickly navigates away and back.

Consider an alternative pattern using a single auto-join attempt tracked by a flag set in the constructor:
private autoJoinAttempted = false;

effect(() => {
  if (this.shouldAttemptAutoJoin() && !this.autoJoinAttempted) {
    this.autoJoinAttempted = true;
    setTimeout(() => this.performAutoJoin(), 500);
  }
});
This would eliminate the need for allowSignalWrites and the timeout clearing logic.

124-130: LGTM! Proper cleanup implemented.

The cleanup logic correctly clears pending timeouts to prevent memory leaks when the component is destroyed.

407-435: LGTM! Clean computed signal implementations.

The message severity and icon helpers use computed signals appropriately to derive UI state from the auto-join and meeting status.

437-457: LGTM! Excellent security and UX handling.

The openMeetingSecurely method properly addresses the security and popup blocker concerns from previous reviews:

Uses noopener,noreferrer in window.open features

Clears the opener reference for security

Detects popup blockers and shows appropriate user feedback

Resets hasAutoJoined to allow manual retry

214-216: Avoid nested ternaries in template; compute severity/icon in TS for clarity

Move this logic into computed signals/getters and bind them here. Improves readability and keeps template simple.

Example change in template:
- [severity]="hasAutoJoined() ? 'success' : (canJoinMeeting() ? 'info' : 'warn')"
- [icon]="hasAutoJoined() ? 'fa-light fa-external-link' : (canJoinMeeting() ? 'fa-light fa-check-circle' : 'fa-light fa-clock')"
+ [severity]="messageSeverity()"
+ [icon]="messageIcon()"
Add in component.ts:
public messageSeverity = computed(() =>
  this.hasAutoJoined() ? 'success' : (this.canJoinMeeting() ? 'info' : 'warn')
);
public messageIcon = computed(() =>
  this.hasAutoJoined() ? 'fa-light fa-external-link' : (this.canJoinMeeting() ? 'fa-light fa-check-circle' : 'fa-light fa-clock')
);
220-223: Add stable data-testid to the status message

Add a data-testid on the lfx-message for reliable e2e targeting (per guidelines).

As per coding guidelines

Example:
<lfx-message ... [attr.data-testid]="'join-status-message'">
apps/lfx-one/src/app/modules/meeting/meeting-join/meeting-join.component.ts (2)
72-74: Type the timeout correctly

Avoid any. Use the platform-safe timeout return type.
-  public hasAutoJoined: WritableSignal<boolean> = signal<boolean>(false);
-  private autoJoinTimeout: any = null;
+  public hasAutoJoined: WritableSignal<boolean> = signal<boolean>(false);
+  private autoJoinTimeout: ReturnType<typeof setTimeout> | null = null;
404-406: Avoid deprecated unescape; encode Unicode safely for base64

Use TextEncoder to base64-encode UTF‑8 correctly.
-    const encodedName = btoa(unescape(encodeURIComponent(displayName)));
+    const encodedName = btoa(String.fromCharCode(...new TextEncoder().encode(displayName)));

93-124: Auto-join scheduling looks solid

Timeout cleared on re-runs, guarded by hasAutoJoined and canJoinMeeting; onDestroy cleanup present. No change needed.

Please test auto-join across Chrome/Safari/Firefox with popup blockers enabled to ensure the TS-side handling (below) covers real-world behavior.

126-132: Good cleanup on destroy

Clearing the pending timeout avoids leaks.
