Vue.js

Vue.js is an open-source JavaScript framework for building user interfaces and single-page applications (SPAs). It is called progressive because it can be adopted gradually — from a simple script that enlivens part of an existing page all the way to a full application architecture with routing, state management and build tooling.

Reactivity and components

The foundation of Vue is a reactive data model: when the application state changes, the framework automatically and efficiently updates only the parts of the view affected by the change, using a virtual DOM. Interfaces are built from components — self-contained, reusable building blocks that combine template, logic and styling, which makes code easier to maintain and extend.

Vue compared to other frameworks

Vue is often compared with React and Angular. It differs from React in its template syntax, which stays close to plain HTML, and in a gentler learning curve, and from Angular in its smaller size and greater flexibility. Like every modern front-end framework, Vue works with tools that bundle code, supports server-side rendering for better SEO and performance, and has a rich ecosystem of libraries. Its large community, extensive documentation and many ready-made libraries shorten the time needed to build common interface features and make it easier to find developers who know it. For a product owner, the choice of framework affects development speed, the availability of engineers and long-term maintenance cost, so the decision is best made in the context of a specific project rather than fashion.
