## What it is
W2UI is a lightweight JavaScript UI widget library for building rich web applications declaratively via JSON data structures. It provides grid, form, toolbar, sidebar, tabs, popup, and layout components in a single ~120KB gzipped bundle with no dependencies as of v2.0.

## Use cases
- add an advanced data table with sorting and filtering to a web app
- build forms declaratively from JSON definitions
- create tabbed interfaces and sidebars without a heavy framework
- add popups, tooltips, and toolbars to vanilla JS projects
- embed rich UI widgets in React, Angular, or Vue apps
- build admin dashboards with layout panels and grids

## When to choose
- you want a full set of UI widgets in one small dependency-free bundle
- you prefer defining UI declaratively with JSON
- you need a powerful data grid without pulling in a large framework
- you mix vanilla JS with React/Vue/Angular and need shared widgets

## When to avoid
- you need a component ecosystem with theming and a large community
- you want fine-grained reactive rendering like modern frameworks provide
- you need mobile-first touch-optimized components
- you require TypeScript-first APIs

## Facets
- artifact type: library
- maturity: stable

- domain: web-development, frontend
