Issues

Most of the implementation choices for this component are based on use cases I've encountered in the past. For example, I chose a click to zoom trigger because it was requested on previous product detail pages I've worked on. If there's a demand for zoom on hover or other additional functionality, I'd be open to taking a look.

One of my big motivations for adapting this component from the original React Inner Image Zoom was to give Vue a try so don't hesitate to flag any areas in the code or the documentation where I'm not following Vue's best practices.
