Vue.js is a progressive JavaScript framework for building user interfaces and single-page applications. Created by Evan You and maintained by an open-source community, Vue.js is designed to be incrementally adoptable and focuses on the view layer. It integrates with other libraries or existing projects and powers complex single-page applications when combined with modern tooling like Vue Router, Pinia state management, and Vite build tooling. Vue.js is one of the most popular frontend frameworks with over 4 million weekly npm downloads and a rich ecosystem of components and plugins.
