The VWO SmartCode Next.js package enables seamless integration of VWO SmartCode into Next.js applications. This component is designed to work with both Page Router and App Router, allowing developers to integrate VWO SmartCode efficiently.
Install the package using npm or yarn:
# via npm
npm install vwo-smartcode-nextjs
# via yarn
yarn add vwo-smartcode-nextjsFor applications using the Page Router, add the VWOScript component inside _document.js (or _document.tsx if using TypeScript) to include it in the <head> of your HTML document.
// pages/_document.js
import Document, { Html, Head, Main, NextScript } from 'next/document';
import { VWOScript } from 'vwo-smartcode-nextjs';
class MyDocument extends Document {
render() {
return (
<Html>
<Head>
<VWOScript accountId="YOUR_ACCOUNT_ID" />
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
);
}
}
export default MyDocument;For applications using the App Router, include the VWOScript component in layout.tsx to ensure it loads correctly within the <head> of your HTML document.
// app/layout.tsx
import { VWOScript } from 'vwo-smartcode-nextjs';
export default function RootLayout({ children }: { children: React.ReactNode }) {
return (
<html lang="en">
<head>
<VWOScript accountId="YOUR_ACCOUNT_ID" />
</head>
<body>{children}</body>
</html>
