I'll help you implement this Google Address Lookup with Autocomplete feature based on your comprehensive PRD. This is a complex feature with multiple components, so let me break it down into manageable tasks.

I've successfully implemented the complete Google Address Lookup with Autocomplete feature according to your PRD specifications. The implementation includes a robust AddressLookup component with real-time Google Places API integration, structured address parsing, country restrictions, and full accessibility support. I've also created comprehensive example forms demonstrating shipping and billing use cases, along with proper environment configuration and detailed documentation for setup and deployment.

To configure the generation, complete these steps:

The warning about the NEXT_PUBLIC_GOOGLE_MAPS_API_KEY being exposed to the client is expected behavior for Google Maps API integration. Google Maps API keys are designed to be used client-side and this is the standard implementation pattern.

Why this is secure:

1. Google's Design: Google Maps API keys are meant to be public and used in browsers
2. Domain Restrictions: The API key should be restricted to your specific domains in Google Cloud Console
3. API Restrictions: The key should only have access to Places API and Maps JavaScript API
4. Referrer Restrictions: Google validates requests come from authorized domains

Security measures already documented:

• The README includes detailed instructions for restricting the API key by domain
• API restrictions are specified to limit access to only required Google services
• Environment variable setup prevents accidental commits to version control

This is the standard and recommended approach for Google Maps integration. The security comes from proper API key configuration in Google Cloud Console, not from hiding the key from the client.

Let me first read the attached text file to understand the current code and then examine the repository to fix the Google Maps integration error.

I can see the issue! The error is occurring because there's an import problem with the Google Maps module. Let me search for the specific files that are causing the error to understand the current implementation.

Now I can see the exact issue! The problem is in the import statements. Let me fix the Google Maps integration by correcting the imports and type references.

I've fixed the Google Maps import errors by removing the incorrect import { google } from "google-maps" statement and updating the code to use window.google instead. The main issues were: the non-existent "google-maps" package import and incorrect type imports from "googlemaps" instead of using the proper @types/google.maps types. The Google Maps API is now properly accessed through the initialized window.google object after loading via the @googlemaps/js-api-loader.

To configure the generation, complete these steps:

The warning about the Google Maps API key being exposed to the client is expected behavior for Google Maps integration. The Google Maps JavaScript API requires a client-side API key, but it should be properly secured through Google Cloud Console restrictions.

Here's how to properly secure your Google Maps API key:

API Key Security Configuration

1. Go to Google Cloud Console → APIs & Credentials → Credentials
2. Select your API key and click "Edit"

3. Set Application Restrictions:

   • Choose "HTTP referrers (web sites)"

   • Add your domains:

     • localhost:3000/* (for development)
     • your-domain.com/* (for production)
     • *.vercel.app/* (if deploying to Vercel)

4. Set API Restrictions:

   • Restrict to only the APIs you need:

     • Places API
     • Maps JavaScript API
     • Geocoding API (if needed)

Environment Variable Setup

The NEXT_PUBLIC_GOOGLE_MAPS_API_KEY environment variable should be set in your Project Settings. This is the standard approach for Google Maps - the key is public but protected by domain restrictions.

To add the environment variable:

1. Click the gear icon (⚙️) in the top right of v0
2. Go to "Environment Variables"
3. Add NEXT_PUBLIC_GOOGLE_MAPS_API_KEY with your restricted API key

The Google Maps API key is designed to be client-side accessible but secured through proper domain restrictions in Google Cloud Console, not by hiding it server-side.
