What is Vue.js?

Vue.js is a popular open-source JavaScript framework. It is maintained on Github and created by Evan You, a former Google engineer.

From the introduction in the official Vue.js Guide:

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

A more in-depth overview of and introduction to Vue's functionality can be found in the Vue.js guide. The API documentation is available here.

Vue.js documentation also includes a comparison page with other frameworks and popular libraries, such as React or Angular.js, if you're looking for how Vue.js compares to other popular JavaScript frameworks.

For further information and resources, see the main tag wiki.
