# Context: Explore Data Service Performance Optimization
|
|
|
|
**Goal**: Reduce background CPU and battery usage by pausing `ExploreDataService` updates when the tab is hidden.
|
|
|
|
**Scope**:
|
|
- `js/services/exploreDataService.js`
|
|
|
|
**Problem**:
|
|
- The service runs two `setInterval` timers (1 minute and 5 minutes) to refresh watch history counts and tag IDF.
|
|
- These run even when the tab is hidden or minimized, consuming resources unnecessarily.
|
|
|
|
**Proposed Solution**:
|
|
- Modify the interval callbacks to check `document.hidden`. If true, skip the update.
|
|
- Add a `visibilitychange` listener to trigger an immediate update when the tab becomes visible (if the data is stale).
|
|
|
|
**Assumptions**:
|
|
- `document.hidden` is supported in target browsers (modern browsers support it).
|
|
- Users do not need real-time updates for "explore" data when the tab is not visible.
