VanJS is an ultra-lightweight (~1kB), zero-dependency reactive UI framework built on pure vanilla JavaScript and DOM. It offers React-like declarative components and reactive state binding without JSX, transpiling, or a virtual DOM.

Use cases

• build a reactive UI without React or JSX
• add lightweight interactivity to a plain HTML page
• create reusable UI components with plain JavaScript functions
• bind state to the DOM with minimal boilerplate
• prototype a UI app quickly in the browser console
• avoid build tools and transpiling for a small web app

When to choose

• you want React-style reactive UI with a ~1kB footprint and no build step
• you prefer vanilla JavaScript functions over JSX and virtual DOM
• you need zero dependencies and instant setup in any environment
• you're building small-to-medium UIs, widgets, or prototypes

When to avoid

• you need a large ecosystem with routing, SSR, and mature tooling out of the box
• your team relies on TypeScript-first frameworks or JSX conventions
• you're building a complex enterprise app that benefits from a full-featured framework like React or Vue
