useScrollOverflow
@astryxdesign/core v0.7.1 · useScrollOverflow
Usage
Tracks scroll overflow state for a horizontally scrollable container. Returns a ref callback and state booleans that update as the user scrolls or the container resizes. Uses scroll event listeners and ResizeObserver for reactive updates. Tolerance of 1px is applied to avoid sub-pixel false positives.
scrollRef is a function ref, so bind it with :ref="scrollRef". Give the container overflow-x: auto or overflow-x: scroll; the hook only reads the edges the container already has.

| Guidance | Practices |
|---|---|
| Do | Use to show/hide scroll navigation buttons or fade edges on carousels and horizontal lists. |
| Do | Apply the scrollRef to a container with overflow-x: auto or overflow-x: scroll. |
| Don't | Use for vertical scroll tracking; this hook only measures horizontal overflow. |
