Getting Started with React Layout 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/layout/basic/App.jsx

1 Create a Vite + React + TypeScript app

npm create vite@latest my-smart-app -- --template react-ts

```
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 React from "react";
import ReactDOM from 'react-dom/client';
import { Layout, LayoutItem, LayoutGroup } from 'smart-webcomponents-react/layout';

class App extends React.Component {

	init() {

	}

	componentDidMount() {
		this.init();
	}

	render() {
		return (
			<div>
				<Layout>
					<LayoutItem>Item 1</LayoutItem>
					<LayoutItem>Item 2</LayoutItem>
					<LayoutGroup orientation="horizontal">
						<LayoutItem>Item 3</LayoutItem>
						<LayoutItem>Item 4</LayoutItem>
					</LayoutGroup>
				</Layout >
			</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 { Layout, LayoutProps } from 'smart-webcomponents-react/layout';

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

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.
