There are a lot of web development frameworks available.

The first ones that may come to mind include Node.js and React.

Yet, there’s another hidden gem: Vue.js.

This article will cover all aspects of Vue: what it is, its features, and its architecture.

We’ll also discuss this JavaScript framework for building User Interfaces (UIs). Let’s go!

What is Vue?

Vue.js is a Typescript-written, open-source, progressive framework for Web User Interfaces.

Created by Ewan You in 2014, Vue is mainly focused on static website front end.

As of 2024, Vue.js usage statistics show over 200,000 stars on GitHub.

This rank places it among the top JavaScript frameworks in terms of recognition!

What can Vue do?

Vue.js is a versatile tool for standalone scripts, embedded web components and Single-Page Applications (SPAs).

It’s also great for building mobile apps with Ionic Vue, Desktop Apps with Electron or Tauri and cross-platform apps with Quasar.

Due to its flexibility, it's no surprise that Vue is part of many projects.

Products that had Vue in their development include Netflix, Grammarly and GitLab. Other examples are Xiaomi, Trivago and Nintendo.

Vue Key Concepts

• Virtual DOM: The Virtual DOM copies the actual DOM. As a result, Vue can upload the real DOM with recent changes. Revisiting the whole DOM with each small change becomes unnecessary.
• Data Binding: Vue uses one-way data flows between single-file components. Data flows are more manageable and the framework becomes more flexible.
• Computed Properties: These properties handle complex logic and operations. They declaratively describe "how to derive a value based on other values." What’s more, they are highly reactive and updated whenever values change.
• Components: Reusable components help create custom elements in Vue. These authorize HTML to reuse said elements.
• Templates: HTML-based templates bind the rendered DOM to Vue information or instance data.
• Transitions: Vue also allows to perform transitions when introducing, changing or deleting HTML elements. The framework has two built-in transition components: Transition and TransitionGroup.

Vue Architecture

Vue has a modular architecture where individual functionalities don't disrupt the overall architecture.

Moreover, it lies on a Model-View-ViewModel (MVVM) architecture pattern that divides program logic from UI controls.

Programs break into modules to organize the code and simplify and speed up dev and update processes. Let's break this pattern down:

• Vue V Model: The Vue V instance handles the abstraction of data sources. It works with the ViewModel to gather and store data.
• Vue View: The view is the face or presentation layer and handles the data display to the user. Views also inform the ViewModel of user actions.
• Vue ViewModel: The VM Vue instance also receives the name “presentation logic.” The logic of the views serves as a link between views and models.

Vue Latest Updates

As of 2025, we can highlight some stable releases:​

Vue 3.5 (Set 2024): This update receives the name “ Tengen Toppa Gurren Lagann.” One focus was its Reactivity System optimization and refactor for better performance. It improved memory usage (-56%) with no behavior changes. 3.5’s version also brought stabilization to the Reactive Props Destructure.

Vue 3.4 (Dec 2023): Vue’s “ Slam Dunk” included a rewritten template parser that is 2x faster. It also had a refactored reactivity system that made effect triggering more accurate. Other focuses were on its quality-of-life API improvements, with the stabilization of defineModel.

Vue 3.3 (May 2023): There were several additions to Vue’s " Rurouni Kenshin." Some main features included more Ergonomic defineEmits and yped Slots with defineSlots. There were also changes in generic components— those with
