Question 1

How do I implement auto-logout with Ember User Activity?

Accepted Answer

Inject the userIdle service and listen for the 'idleChanged' event; when isIdle becomes true, trigger your logout logic. Configure IDLE_TIMEOUT in the service to set the inactivity period, such as reducing it to 5 minutes for tighter security.

Question 2

Ember User Activity vs using native JavaScript event listeners?

Accepted Answer

Ember User Activity adds built-in throttling, cross-tab synchronization, and Ember service integration, whereas native listeners require manual management and lack these conveniences. However, for simple projects, native listeners might be lighter without the Ember dependency.

Question 3

Can I track scrolling in specific components with this addon?

Accepted Answer

Yes, use the scrollActivity service to subscribe specific elements by passing the element and a callback. You can set highPriority to true for eager checking or false for idle-based optimization, as described in the README.

Question 4

How to change which events trigger user activity tracking?

Accepted Answer

Extend the user-activity service and override the defaultEvents array, or use enableEvent/disableEvent methods at runtime. Event names must be from the DOM Event list, and custom events are not supported.

Question 5

Does Ember User Activity work with the latest Ember versions like Octane?

Accepted Answer

Yes, it's compatible with Ember.js v4.8 and above, which includes Octane. The usage examples in the README use modern syntax like decorators and service injection, ensuring it fits with current Ember practices.

Question 6

What's the performance impact if I disable throttling?

Accepted Answer

Setting EVENT_THROTTLE to 0 disables throttling, which can cause performance issues if event handlers execute complex code, as warned in the README. It's recommended only for low-frequency events or with careful optimization.
