## What it is
Haunted is a TypeScript library that brings React's Hooks API (useState, useEffect, useContext, etc.) to standard web components, using lit-html or hyperHTML as renderers. It lets you define custom elements as plain functions with hooks, reusing existing React hooks from npm via bundler aliasing.

## Use cases
- use react hooks in web components
- build custom elements without a framework
- write function-based web components with state
- reuse react hooks libraries in web components
- lightweight alternative to react for component development
- create web components with lit-html rendering

## When to choose
- you want React-style hooks ergonomics in standards-based web components
- you need framework-agnostic components usable across React, Vue, or plain HTML
- you prefer a tiny library over a full framework like React or Lit

## When to avoid
- you are building a full React application with its ecosystem
- you need class-based web components or Lit's full feature set
- your team has no familiarity with the hooks mental model

## Facets
- artifact type: library
- maturity: active
- function: frontend-framework, ui-components, state-management
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: web-components, react-hooks, lit-html, hyperhtml, custom-elements, shadow-dom, web-server, nodejs
