Walkthrough

A guard clause was introduced at the beginning of the useEffect hook in the AnimationDivider component within LoadingBarDivider.tsx. This clause ensures that the animation logic is only executed if the referenced DOM element (scope.current) is available. No changes were made to the declarations of exported or public entities, and the remainder of the effect logic remains unchanged.

Changes

File(s) Change Summary
apps/webapp/app/components/primitives/LoadingBarDivider.tsx Added a guard clause in the useEffect of AnimationDivider to prevent animation logic from running if scope.current is falsy.

Sequence Diagram(s)

    alt scope.current is falsy
        Component-->>Component: Return early, skip animation logic
    else scope.current is truthy
        Component->>Animation: Run enter/exit animation based on isPresent

  • Loading bar divider – small animation improvement #2012: Both PRs modify the animation logic within the AnimationDivider component of the LoadingBarDivider.tsx file, with the main PR adding a guard clause to prevent animation when the target element is unavailable, while the retrieved PR simplifies and changes the animation behavior itself.

Poem

A hop and a skip, a guard at the gate,
Animation waits if the element’s late.
No more errors, no more race,
Only smooth transitions take their place.
With a whisk of code and a bunny’s cheer,
Loading bars leap—now crystal clear!

21-22: Good defensive programming approach!

Adding this null check prevents the animation code from running when the DOM element reference (scope.current) is not yet available. This effectively addresses the console error that occurred when trying to animate a non-existent element. This is a common pattern in React when working with refs and animations.
