## What it is
Reagent is a minimalistic ClojureScript interface to React.js that lets you write efficient React components using plain ClojureScript functions and Hiccup-like markup instead of JSX. It provides reactive state management via Reagent atoms so components re-render automatically when their data changes.

## Use cases
- build a single-page web app in ClojureScript
- write React components without JSX using Hiccup syntax
- create reactive UIs that re-render on data changes
- use React with alternative renderers beyond react-dom
- build a frontend for a Clojure full-stack application

## When to choose
- you are a Clojure/ClojureScript developer building a web frontend
- you want React's ecosystem with idiomatic functional ClojureScript code
- you prefer data-oriented markup over JSX
- you want simple built-in reactive state management

## When to avoid
- your team works primarily in JavaScript or TypeScript
- you need a framework with a large mainstream hiring pool
- you want JSX and the standard React tooling experience
- you are building a non-web platform without a React renderer

## Facets
- artifact type: library
- maturity: stable
- function: frontend-framework, ui-components, state-management
- domain: web-development, frontend
- platform: browser
- tags: clojurescript, react, hiccup, reactive-ui, reagent, nodejs
