## What it is
cf-ui is a collection of over 50 React-based UI component packages used to build interfaces at Cloudflare, styled with CSS-in-JS via Fela. The repository is no longer maintained, as development has moved into Cloudflare's internal monorepo.

## Use cases
- build React UIs with prebuilt components
- use CSS-in-JS styled React components
- study how Cloudflare structures a large component library
- explore a Lerna-based multi-package UI monorepo
- find React button, form, and layout components

## When to choose
- you are building interfaces for Cloudflare-internal products
- you want to study or fork a React + Fela component framework
- you need a historical reference for CSS-in-JS component design

## When to avoid
- you need a maintained library with active support and accepted pull requests
- you don't want to adopt Fela in your project
- you need stability for production use outside Cloudflare

## Facets
