Mouse event handling enables rich user interactions like clicks, hovers, drag-and-drop, and custom gestures in web applications. As the creator of CoreUI with over 12 years of Vue.js experience since 2014, I’ve implemented complex mouse interactions in enterprise dashboards. Vue provides straightforward event listeners with modifiers to handle mouse events efficiently and declaratively. This approach creates interactive interfaces with tooltips, context menus, draggable elements, and custom behaviors.
