PortalVue for Vue 3

PortalVue is a Vue 3 component library that enables developers to render DOM elements outside of their natural component hierarchy, placing content anywhere in the document. The current stable version is 3.0.0, which targets Vue 3 and ships with full TypeScript types. While the project had a prolonged beta period, the 3.x line is now considered stable and actively maintained, receiving dependency updates and bug fixes as needed. Its primary differentiator is providing a robust, battle-tested solution for portal functionality directly within the Vue ecosystem, often used for modals, tooltips, and other overlay elements, without relying on imperative DOM manipulation. Vue 3 also offers its native `<Teleport>` component, which addresses many typical portal use cases, but PortalVue remains relevant for scenarios involving content movement between application components rather than simply moving to a specific DOM target.
