Getting Started with React RadioButton Component

Smart UI React targets React 18+ and current Node LTS for tooling; use TypeScript templates when you want typed props and events.

Demo source (Smart UI repo): react/source/radiobutton/basic/App.jsx

1 Create a Vite + React + TypeScript app

  1. npm create vite@latest my-smart-app -- --template react-ts
  2. cd my-smart-app
    then 
    npm install

2 Install Smart UI for React

npm install smart-webcomponents-react

3 Import styles and render the component

Open src/App.tsx (or App.jsx if you chose JavaScript). The snippet below matches Smart UI React demos for this widget:

import 'smart-webcomponents-react/source/styles/smart.default.css';
import './App.css';
import React from "react";
import { RadioButton } from 'smart-webcomponents-react/radiobutton';

function App() {
    // useEffect hook can be used if you need componentDidMount logic
    // React.useEffect(() => {
    //     // componentDidMount logic here
    // }, []);

    return (
        <div>
            <RadioButton>Radio Button 1</RadioButton>
            <RadioButton checked>Radio Button 2</RadioButton>
        </div>
    );
}

export default App;

4 Run the dev server

npm run dev

Open the URL Vite prints (often http://localhost:5173/).

Alternative: Next.js

Create an app with npx create-next-app@latest (Pages Router or App Router). Install the same package (npm install smart-webcomponents-react), then reuse the imports and default export from step 3 in pages/_app.tsx, the App Router root app/layout.tsx, or your top-level layout component so styles and the widget tree load once.

TypeScript Support

Types ship with smart-webcomponents-react. Import the component and prop types:

import type { RadioButton, RadioButtonProps } from 'smart-webcomponents-react/radiobutton';

The generated wrappers expose on* callbacks (for example onChange) whose arguments are standard DOM Event values unless the widget typings narrow them further.

Accessibility

The RadioButton component follows WAI-ARIA best practices:

  • Keyboard navigation - Tab, Arrow keys, Enter, and Escape are supported
  • ARIA roles - Appropriate roles and labels are applied automatically
  • Focus management - Visible focus indicators for keyboard users
  • Screen readers - State changes are announced to assistive technology
  • High contrast - Supports Windows High Contrast Mode and forced colors

For custom labeling, set aria-label or aria-labelledby attributes on the component.

Live demos

Supported stacks: Smart UI targets Angular 17+, React 18+, Vue 3+, Node 18 LTS, and evergreen browsers; pin exact package versions to your org policy.
