HeroUI v3

An open-source UI component library for React (web) and React Native (mobile). Built on Tailwind CSS v4 and React Aria Components. Provides 75+ accessible, customizable web components and 40+ native components.

Technology Stack

Platform	Package	Requires
React (Web)	@heroui/react, @heroui/styles	React 19+, Tailwind CSS v4
React Native	heroui-native	React Native, Uniwind, react-native-reanimated 4.1+, react-native-gesture-handler 2.28+

Quick Setup

React (Web)

npm i @heroui/react @heroui/styles

/* globals.css — order matters */
@import "tailwindcss";
@import "@heroui/styles";

import { Button } from "@heroui/react";

function App() {
  return <Button>Click me</Button>;
}

export default function App() {
  return (
    <GestureHandlerRootView style={{ flex: 1 }}>
      <HeroUINativeProvider>
        <Button onPress={() => console.log("Pressed!")}>Get Started</Button>
      </HeroUINativeProvider>
    </GestureHandlerRootView>
  );
}

Component Architecture

HeroUI v3 uses compound component composition with dot notation:

<Modal>
  <Button>Open</Button>
  <Modal.Backdrop>
    <Modal.Container>
      <Modal.Dialog>
        <Modal.Header>
          <Modal.Heading>Title</Modal.Heading>
        </Modal.Header>
        <Modal.Body>Content</Modal.Body>
        <Modal.Footer>
          <Button slot="close">Close</Button>
        </Modal.Footer>
      </Modal.Dialog>
    </Modal.Container>
  </Modal.Backdrop>
</Modal>

Three Import Patterns

// 1. Compound (recommended)
<Alert>
  <Alert.Icon />
  <Alert.Content>
    <Alert.Title>Success</Alert.Title>
  </Alert.Content>
</Alert>

// 2. With .Root suffix
<Alert.Root>
  <Alert.Icon />
</Alert.Root>

// 3. Named exports
import { AlertRoot, AlertIcon, AlertContent, AlertTitle } from "@heroui/react";

Type Imports

import type { ButtonRootProps, AvatarRootProps } from "@heroui/react";

Styling System

HeroUI v3 provides three styling approaches:

1. BEM Classes

<button className="button button--primary button--lg">Click</button>

Class pattern: .{block}, .{block}__{element}, .{block}--{modifier}

2. Variant Functions (Type-Safe)

import { buttonVariants } from "@heroui/styles";

<a className={buttonVariants({ variant: "primary", size: "lg" })} href="/about">
  About
</a>

Variant functions are framework-agnostic — usable with Vue, Svelte, vanilla HTML.

3. Tailwind CSS Classes + className Prop

<Button className="rounded-full shadow-lg">Styled</Button>

Custom Variants

import { buttonVariants, tv } from "@heroui/styles";

const myButton = tv({
  extend: buttonVariants,
  base: "font-semibold shadow-md",
  variants: {
    radius: { lg: "rounded-lg", md: "rounded-md" },
  },
});

render Prop for Custom Elements

<Button
  render={(domProps, { isPressed }) => (
    <motion.button {...domProps} animate={{ scale: isPressed ? 0.9 : 1 }} />
  )}
>
  Animated
</Button>

For theming, CSS variables, dark mode, custom themes, and component-level overrides, see theming-and-styling.md.

Common Prop Patterns

Interactive States (Data Attributes)

State	Attribute	CSS Pseudo
Hover	[data-hovered="true"]	:hover
Pressed	[data-pressed="true"]	:active
Focus	[data-focus-visible="true"]	:focus-visible
Disabled	[aria-disabled="true"]	:disabled
Selected	[data-selected="true"]	—
Open	[data-open="true"]	—
Entering	[data-entering]	—
Exiting	[data-exiting]	—

Event Handlers

HeroUI uses React Aria's press events, not native click events:

<Button onPress={(e) => console.log("pressed")} />

Overlay State Management

import { useOverlayState } from "@heroui/react";

const state = useOverlayState({ defaultOpen: false });
// state.isOpen, state.open(), state.close(), state.toggle(), state.setOpen()

Form Validation

import { Form, TextField, Button } from "@heroui/react";

<Form validationBehavior="aria" onSubmit={handleSubmit}>
  <TextField name="email" isRequired>
    <Label>Email</Label>
    <Input />
    <FieldError />
  </TextField>
  <Button type="submit">Submit</Button>
</Form>

Two validation modes: "native" (blocks submission) and "aria" (realtime errors).
