Database: Update the MONGODB_URI in your .env file with the production database credentials. Verify and adjust the database name, host, and any additional connection options (e.g., replica sets, connection pool settings). Backend: Change the CORS origin from http://localhost:5173 to your deployed front-end URL. Adjust middleware or static file paths if your production directory structure differs. Update API route configurations if there are any changes in the endpoints or business logic. Modify error handling (e.g., reducing detailed error output) to suit a production environment. Change the server port (via process.env.PORT or hardcoded) if necessary for your deployment. Front End: Update the API base URL in your front-end configuration to point to your production backend. Replace any hardcoded local URLs (like http://localhost:5173 ) with the production URL. Ensure that any environment-specific settings (e.g., API endpoints, port numbers) are correctly set for the...
