Radix UI Composition

Radix UI Composition sits at the heart of radix ui in UI libraries. This guide walks through the concept step by step, with examples, a cheatsheet, and common mistakes to avoid.

Radix UI Composition Overview

At its core, radix ui composition is about doing one thing well in UI libraries. Once you understand the pattern, you can apply it consistently across projects and teams.

Good radix ui composition pays off across the whole project: fewer surprises, easier collaboration, and smoother onboarding. The snippet below is a solid starting point.

import * as Dialog from '@radix-ui/react-dialog';

function Modal() {
  return (
    <Dialog.Root>
      <Dialog.Trigger>Open</Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Overlay />
        <Dialog.Content>Hello</Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

Headless libraries provide accessible behaviour and leave all styling to you.

Radix UI Composition Example

// install, import, and use a component
// npm install <library>
import { Button } from '<library>';

<Button variant="primary">Click me</Button>
  • Start from a minimal Radix UI Composition example and grow it only as needed.
  • Keep things explicit so Radix UI Composition behaves the same for everyone on the team.
  • Name things clearly so teammates understand your Radix UI Composition at a glance.
  • Verify Radix UI Composition works as expected before relying on it in important work.

How Radix UI Composition Works

Radix UI Composition fits into the wider ecosystem of UI libraries, which trade a little flexibility for speed, consistency, and built-in accessibility. Understanding the model helps you choose and use it well.

Headless libraries provide accessible behaviour and leave all styling to you.

  • Component kits give styled, ready-to-use building blocks.
  • Headless libraries provide behaviour and leave styling to you.
  • Utility-first tools compose styles directly in markup.

Factor What to check
Accessibility Correct roles, ARIA, keyboard support
Customisation Theming and style overrides
Bundle size Tree-shaking and import cost
Ecosystem Docs, maintenance, community
