Vue.js is an approachable, performant, and versatile JavaScript framework designed for building web user interfaces. It builds on standard HTML, CSS, and JavaScript, offering an intuitive API and world-class documentation, making it easy for developers to get started. Vue features a truly reactive, compiler-optimized rendering system that minimizes the need for manual optimization, ensuring high performance.
Vue provides a rich and incrementally adoptable ecosystem, allowing it to scale from a lightweight library to a full-featured framework. It is a mature, battle-tested, and widely used framework, powering applications for organizations like Wikimedia Foundation, NASA, Apple, and Google. Vue 3, the latest major version, offers smaller bundle sizes, better performance, improved scalability, and enhanced TypeScript/IDE support, making it the recommended choice for new projects.
