Add the Vercel Toolbar to your local environment

To enable the toolbar in your local environment, add it to your project using the @vercel/toolbar package, or with an injection script.

  1. Install the package using the following command:

    pnpm i @vercel/toolbar

    Then link your local project to your Vercel project with the vercel link command using Vercel CLI.

    terminal
    vercel link [path-to-directory]
  2. To use the Vercel Toolbar locally in a Next.js project, define withVercelToolbar in your next.config.js file and export it, as shown below:

    next.config.js
    /** @type {import('next').NextConfig} */
    const nextConfig = {
      // Config options here
    };
     
    const withVercelToolbar = require('@vercel/toolbar/plugins/next')();
    // Instead of module.exports = nextConfig, do this:
    module.exports = withVercelToolbar(nextConfig);

    Then add the following code to your layout.tsx or layout.jsx file:

    app/layout.tsx
    import { VercelToolbar } from '@vercel/toolbar/next';
     
    export default function RootLayout({
      children,
    }: {
      children: React.ReactNode;
    }) {
      const shouldInjectToolbar = process.env.NODE_ENV === 'development';
      return (
        <html lang="en">
          <body>
            {children}
            {shouldInjectToolbar && <VercelToolbar />}
          </body>
        </html>
      );
    }
