React Aria Components sits at the heart of react aria in UI libraries. This guide walks through the concept step by step, with examples, a cheatsheet, and common mistakes to avoid.
React Aria Components Overview
React Aria Components is something you will reach for often in UI libraries. It keeps your workflow predictable and makes your intent obvious to reviewers and teammates.
When you learn react aria components properly, you avoid the guesswork that leads to mistakes and rework. The example below shows the shape you will use in most real UI libraries projects.
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.
React Aria Components Example
// install, import, and use a component
// npm install <library>
import { Button } from '<library>';
<Button variant="primary">Click me</Button>
Start from a minimal React Aria Components example and grow it only as needed.
