The `WebPreview` component provides a flexible way to showcase the result of a generated UI component, along with its source code. It is designed for documentation and demo purposes, allowing users to interact with live examples and view the underlying implementation.
<Preview path="web-preview" />
## Installation
<ElementsInstaller path="web-preview" />
## Usage
```tsx
import { WebPreview, WebPreviewNavigation, WebPreviewUrl, WebPreviewBody } from "@/components/ai-elements/web-preview";
```
```tsx
<WebPreview defaultUrl="https://ai-sdk.dev" style={{ height: "400px" }}>
<WebPreviewNavigation>
<WebPreviewUrl src="https://ai-sdk.dev" />
</WebPreviewNavigation>
<WebPreviewBody src="https://ai-sdk.dev" />
</WebPreview>
```
## Usage with AI SDK
Build a simple v0 clone using the [v0 Platform API](https://v0.dev/docs/api/platform).
Install the `v0-sdk` package:
```package-install
npm i v0-sdk
```
Add the following component to your frontend:
```tsx title="app/page.tsx"
"use client";
import { WebPreview, WebPreviewBody, WebPreviewNavigation, WebPreviewUrl } from "@/components/ai-elements/web-preview";
import { useState } from "react";
import { Input, PromptInputTextarea, PromptInputSubmit } from "@/components/ai-elements/prompt-input";
import { Loader } from "../ai-elements/loader";
const WebPreviewDemo = () => {
const [previewUrl, setPreviewUrl] = useState("");
const [prompt, setPrompt] = useState("");
const [isGenerating, setIsGenerating] = useState(false);
const handleSubmit = async (e: React.FormEvent) => {
e.preventDefault();
if (!prompt.trim()) return;
setPrompt("");
setIsGenerating(true);
try {
const response = await fetch("/api/v0", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ prompt }),
});
const data = await response.json();
setPreviewUrl(data.demo || "/");
console.log("Generation finished:", data);
} catch (error) {
console.error("Generation failed:", error);
} finally {
setIsGenerating(false);
}
};
return (
<div className="max-w-4xl mx-auto p-6 relative size-full rounded-lg border h-[600px]">
<div className="flex flex-col h-full">
<div className="flex-1 mb-4">
{isGenerating ? (
<div className="flex flex-col items-center justify-center h-full">
<Loader />
<p className="mt-4 text-muted-foreground">Generating app, this may take a few seconds...</p>
</div>
) : previewUrl ? (
<WebPreview defaultUrl={previewUrl}>
<WebPreviewNavigation>
<WebPreviewUrl />
</WebPreviewNavigation>
<WebPreviewBody src={previewUrl} />
</WebPreview>
) : (
<div className="flex items-center justify-center h-full text-muted-foreground">Your generated app will appear here</div>
)}
</div>
<Input onSubmit={handleSubmit} className="w-full max-w-2xl mx-auto relative">
<PromptInputTextarea
value={prompt}
placeholder="Describe the app you want to build..."
onChange={(e) => setPrompt(e.currentTarget.value)}
className="pr-12 min-h-[60px]"
/>
<PromptInputSubmit
status={isGenerating ? "streaming" : "ready"}
disabled={!prompt.trim()}
className="absolute bottom-1 right-1"
/>
</Input>
</div>
</div>
);
};
export default WebPreviewDemo;
```
Add the following route to your backend:
```ts title="app/api/v0/route.ts"
import { v0 } from "v0-sdk";
export async function POST(req: Request) {
const { prompt }: { prompt: string } = await req.json();
const result = await v0.chats.create({
system: "You are an expert coder",
message: prompt,
modelConfiguration: {
modelId: "v0-1.5-sm",
imageGenerations: false,
thinking: false,
},
});
return Response.json({
demo: result.demo,
webUrl: result.webUrl,
});
}
```
