Great! Now that you've added the environment variables to your Vercel project, let's verify the integration and provide some additional guidance for production deployment.
To ensure your frontend and backend are properly connected, follow these steps:
Now that you've integrated your frontend and backend, here are some important considerations for production deployment:
For your Spring Boot backend:
Environment Configuration: Make sure to set up proper production environment variables
SPRING_PROFILES_ACTIVE=prod
SPRING_DATASOURCE_URL=jdbc:postgresql://your-db-host:5432/skillshare
SPRING_DATASOURCE_USERNAME=your-db-username
SPRING_DATASOURCE_PASSWORD=your-db-password
JWT_SECRET=your-secure-jwt-secretCORS Configuration: Update the allowed origins in production
// In WebConfig.java
registry.addMapping("/api/**")
.allowedOrigins("https://your-production-domain.com")Security Hardening:
For your Next.js frontend on Vercel:
Environment Variables: Ensure these are correctly set in your Vercel project settings
NEXT_PUBLIC_API_URL=https://your-backend-api.com/api
API_URL=https://your-backend-api.com/apiBuild Configuration: Optimize your build for production
npm run build/test-connection in your applicationIf the test fails:
By following these guidelines, you should have a robust integration between your Spring Boot backend and Next.js frontend, ready for production use. The test component will help you quickly verify that everything is working correctly.
Let's fix the network error in the skills-list component. The issue is likely occurring because the backend isn't accessible during the Vercel preview. I'll update the code to handle this gracefully with fallback data:
I've made several improvements to address the network error you encountered:
The SkillsList component now has a robust error handling mechanism that:
The API client now has:
The skill service has been updated with:
I've added a comprehensive Skill interface that matches both the backend model and the frontend needs, ensuring type safety throughout the application.
This solution addresses the root causes of the network error:
These changes ensure your application remains functional and provides a good user experience even when facing connectivity issues with the backend.
