Next.js Token Handler Component

This project includes a reusable client component for Next.js that handles token storage from URL parameters.

TokenHandler Component

The TokenHandler component is designed to:

1. Extract a token from URL parameters
2. Store the token in localStorage
3. Redirect the user to a specified path

Usage

import TokenHandler from '@/components/TokenHandler';

export default function AuthCallbackPage() {
  return (
    <div>
      <h1>Authentication Callback</h1>
      <TokenHandler 
        redirectPath="/dashboard" 
        tokenParamName="token" 
        storageKey="auth_token" 
      />
    </div>
  );
}

Props

The component accepts the following props:

• redirectPath (optional): Path to redirect after storing token (default: '/')
• tokenParamName (optional): Name of the URL parameter containing the token (default: 'token')
• storageKey (optional): Key to use when storing in localStorage (default: 'auth_token')

Example URL

After authentication, redirect users to:

https://your-domain.com/auth/callback?token=your-auth-token

Implementation Details

• Uses Next.js's useSearchParams hook to access URL parameters
• Uses useRouter for client-side navigation after token storage
• Includes error handling for localStorage operations
• Displays a loading message while processing

Security Considerations

• This implementation assumes the token is passed securely
• Consider using HTTPS to prevent token interception
• For enhanced security, consider using HTTP-only cookies instead of localStorage
• The token in the URL might be visible in browser history and server logs

This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.
