This article demonstrates how to build a location-aware Node.js website using Next.js and the IP2Location IP2Proxy web service. The site redirects users to different landing pages based on their country of origin, and blocks anonymous traffic from networks like Tor.

The project leverages the IP2Proxy API, a RESTful service providing geolocation data in JSON format. Key data points retrieved include countryName, cityName, isProxy, and proxyType. The application features:

• Home Page: Initiates the IP geolocation lookup and subsequent redirection.
• Landing Page: Displays product information tailored to the user's country (e.g., local currency).
• Unavailable Page: Informs users from unsupported countries, offering a waiting list option.
• Abuse Page: Redirects users from Tor networks.

Key Features and Implementation:

• IP2Location Integration: The core functionality relies on fetching geolocation data from the IP2Proxy API using isomorphic-unfetch.
• Anonymous Traffic Blocking: The application effectively blocks access from Tor networks.
• Context API: A Next.js context API (proxy-context) manages and shares geolocation data across components. This ensures data persistence across page refreshes using localStorage.
• Redirection Logic: The useRouter hook facilitates redirection to appropriate pages based on the retrieved geolocation information.
• Error Handling: Robust error handling is implemented using Next.js's built-in error page.
• Styling: Bulma CSS framework provides the site's styling.
• Deployment: The article guides deployment using Vercel's serverless platform, emphasizing secure management of API keys via environment variables.

Prerequisites:

• Node.js (LTS version recommended)
• Yarn (optional, but recommended for faster dependency management)
• Familiarity with React and React Hooks
• Next.js (basic understanding is helpful)

Step-by-Step Guide (Simplified):

1. Project Setup: Create a Next.js app using npx create-next-app.
2. Install Dependencies: Install necessary packages (Bulma, next-compose-plugins, dotenv-load, next-env, @zeit/next-css, isomorphic-unfetch).
3. Obtain API Key: Sign up for an IP2Proxy API key (free trial available).
4. Configure .env: Store the API key securely in a .env file (exclude from version control).
5. Implement Context API: Create a context to manage and share geolocation data.
6. Build Landing Pages: Create pages for home, landing, unavailable, and abuse scenarios.
7. Fetch Geolocation Data: Use getInitialProps to fetch data from the IP2Proxy API.
8. Implement Redirection: Use useRouter to redirect based on geolocation data.
9. Deploy: Deploy the application to Vercel (or a similar platform).

Testing:

The article suggests testing with free proxy services to simulate different geographic locations and with the Tor browser to verify anonymous traffic blocking.

Local Database Alternative:

The article mentions the option of using a local IP2Location database for improved performance, suggesting cloud database solutions (like MongoDB) or Docker for deployment.

Further Applications:

The article concludes by highlighting additional uses for IP2Location data, such as personalized offers and fraud detection.
