## What it is
Hoplon is a ClojureScript library for building single-page web applications from highly composable DOM elements. It integrates tightly with the Javelin spreadsheet-like dataflow library to reactively bind DOM elements to a cell graph.

## Use cases
- build single-page web apps in ClojureScript
- create composable UI elements with reactive data binding
- write frontend code with a functional programming style
- bind DOM updates to reactive state cells
- avoid JavaScript framework complexity using ClojureScript

## When to choose
- you are a Clojure/ClojureScript developer building a single-page web application
- you want reactive UI bindings via Javelin cells without a virtual DOM framework
- you prefer composing UI from plain DOM elements functionally

## When to avoid
- your team does not know Clojure or ClojureScript
- you need a large ecosystem of ready-made React-style components
- you are building a server-rendered or SEO-critical multi-page site

## Facets
- artifact type: library
- maturity: maintenance
- function: frontend-framework, state-management, templating, ui-components
- domain: web-development, frontend, programming-languages
- platform: browser, cross-platform
- tags: clojurescript, reactive-programming, javelin, single-page-applications, dom, functional-programming, web-server
