Furl

Furl is a functional React.js component library that provides reusable UI elements for building web interfaces. It is distributed as two npm packages—furl-components for React components and furl-styles for accompanying CSS—and is maintained on GitHub under the Chalarangelo organization.

What is Furl?

Furl is an open-source collection of React components written in a functional style, leveraging React hooks for state and side effects. The library takes React props as input and renders UI components as output, which developers can compose into larger interfaces. It is installed via npm or yarn, making it easy to integrate into existing React projects. The project is developed by Chalarangelo (Angelos Chalaris) and hosted on GitHub, with a documentation website at furl.netlify.com.

Key Features

• Functional React components — The library's components are built as functional components that use React hooks, aligning with modern React development patterns.
• Separate styles package — Styles are distributed through furl-styles, letting developers manage component logic and CSS independently.
• npm and yarn support — Install with npm install furl-components furl-styles or yarn add furl-components furl-styles.
• Open source licensing — The repository is publicly available on GitHub and includes an open source license badge.
• Documentation website — The official site at furl.netlify.com provides usage examples and component information.

Who is it for?

React developers who want pre-built UI components can use Furl to skip writing common interface elements from scratch. UI engineers looking for a functional component library might favor Furl's approach to building with hooks and pure functions. Teams using React with SCSS or other CSS preprocessors can integrate furl-styles to maintain a consistent design system.

How does Furl work?

After installing both packages, developers import the desired components from furl-components and the corresponding styles from furl-styles into their React application. Each component accepts props to control its behavior and appearance, and because they are functional, they can be easily tested and composed with other hooks.

Pricing

Furl is free to use because it is open source and released on GitHub under a public license.
