Vue

Vue is a progressive JavaScript framework for building user interfaces. It is designed to be incrementally adoptable, focusing on the view layer but easily combined with other libraries or existing projects. Vue was created by Evan You and first released in 2014. It has grown into a widely used ecosystem for developing single-page applications and web interfaces.

Core concepts include a component-based model, a declarative rendering system, and a reactivity system that tracks dependencies and updates the DOM efficiently. Templates in Vue use an HTML-based syntax, though render functions and the Composition API provide alternatives. Single-file components with .vue extension package template, script, and style.

Vue 3 introduced a rewritten reactivity system based on ES6 proxies, improved TypeScript support, and a Composition API to organize logic. The traditional Options API remains available. The core library is intentionally small; additional features are provided via official libraries such as Vue Router for client-side routing and state management solutions like Pinia (and Vuex in earlier versions). Build tooling includes Vue CLI and Vite.

The project is MIT licensed and maintained by a core team with broad community involvement. Vue is known for its gentle learning curve and compatibility with other libraries. It is used by numerous organizations and developers worldwide, particularly for SPAs and progressively enhanced applications. In comparison to other frameworks, Vue emphasizes simplicity and flexibility.

The philosophy of being progressive means developers can adopt Vue incrementally, using it for a part of an interface or as a full framework for large-scale apps.
