kk-cookie-banner v1.1.1

KK Cookie Banner

A reusable cookie consent banner component for React applications. This component handles user consent for cookies and integrates Google Analytics based on user preferences.

Features

• Encrypts and decrypts user consent data
• Stores consent data in cookies
• Integrates with Google Analytics based on user consent
• Fully customizable and easy to use

Installation

To install the package, run:

npm install kk-cookie-banner

You'll also need to have react, js-cookie, and crypto-js installed in your project. If they are not already installed, you can install them using:

npm install react js-cookie crypto-js

Usage

Import the Component

First, import the CookieBanner component into your React application:

import React from 'react'; import CookieBanner from 'my-cookie-banner';

const App = () => { return (

<div>
  <CookieBanner
    secretKey={process.env.NEXT_PUBLIC_SECRET_KEY_CONSENT}
    measurementId={process.env.NEXT_PUBLIC_MEASUREMENT_ID}
    apiEndpoint="/api/set-consent"
    domain="yourdomain.com"
  />
  {/* Your application content */}
</div>

); };

export default App;

Add API Route

Create an API route to handle the consent data. Here's an example of a Next.js API route:

// pages/api/set-consent.js

import { NextResponse } from 'next/server'; import CryptoJS from 'crypto-js';

const SECRET_KEY = process.env.NEXT_PUBLIC_SECRET_KEY_CONSENT;

const decryptData = (data) => { try { const bytes = CryptoJS.AES.decrypt(data, SECRET_KEY); return JSON.parse(bytes.toString(CryptoJS.enc.Utf8)); } catch (error) { console.error('Decryption error:', error); throw new Error('Decryption failed'); } };

export async function POST(request) { try { const { consent } = await request.json();

const decryptedConsent = decryptData(consent);
console.log('Decrypted consent:', decryptedConsent);

const response = NextResponse.json({ success: true });
response.cookies.set({
  name: 'cookie_consent',
  value: consent,
  secure: true,
  sameSite: 'strict',
  path: '/',
  domain: 'yourdomain.com',
  maxAge: 365 * 24 * 60 * 60,
});

return response;

} catch (error) { console.error('Error in API route:', error); return new NextResponse('Internal Server Error', { status: 500 }); } }

Environment Variables

Make sure to define the necessary environment variables in your project:

NEXT_PUBLIC_SECRET_KEY_CONSENT: The secret key used for encrypting and decrypting consent data. NEXT_PUBLIC_MEASUREMENT_ID: Your Google Analytics measurement ID.

You can set these variables in a .env file:

NEXT_PUBLIC_SECRET_KEY_CONSENT=your-secret-key NEXT_PUBLIC_MEASUREMENT_ID=your-measurement-id

Customize the Banner

You can customize the styles and text of the banner by modifying the CookieBanner component. The default styles are defined in the styles object within the component.
