## What it is
Umbrella JS is a lightweight (~3kb gzipped) JavaScript library for DOM traversal, DOM manipulation, and event handling, with a jQuery-like API. It has zero dependencies and is distributed via npm, CDN, or direct download.

## Use cases
- replace jQuery in a small website
- attach click handlers to buttons with minimal JavaScript
- traverse and filter DOM elements with CSS selectors
- handle form submissions via AJAX
- create and append HTML elements on the fly
- keep page payload tiny for mobile performance

## When to choose
- you want jQuery-like ergonomics in under 3kb gzipped
- you need simple DOM manipulation and events without a full framework
- you are migrating away from jQuery on a small project
- you want a zero-dependency library usable via CDN or bundler

## When to avoid
- you are building a complex SPA needing state management and routing
- you prefer modern native DOM APIs and don't need a wrapper
- you need a large ecosystem of plugins and community support
- you need reactive UI rendering

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: dom-manipulation, event-handling, jquery-alternative, tiny-library, zero-dependencies, nodejs
