I'll create a full MERN stack application that allows you to chat with different AI models including OpenAI, Anthropic Claude, and Perplexity. This application will use the AI SDK, which provides a unified interface for working with different AI models 1.
This MERN stack application allows you to chat with different AI models through a unified interface. Here's a breakdown of the key components:
npm installCreate a .env.local file with the following variables:
MONGODB_URI=your_mongodb_connection_string
NEXTAUTH_SECRET=your_nextauth_secret
NEXTAUTH_URL=http://localhost:3000npm run devYou'll need to set up the following environment variables:
MONGODB_URI=your_mongodb_connection_string
NEXTAUTH_SECRET=your_nextauth_secret
NEXTAUTH_URL=http://localhost:3000For this application to work properly, you'll need API keys from the following providers:
You can add these keys in the Settings page of the application.
Here are some ways you could extend this application:
If you encounter any issues:
Please make sure to add the following environment variables to your project:
I'll fix the SessionProvider error by adding it to the root layout. This is needed for the useSession hook to work properly throughout the application.
This fix addresses the deployment error by:
Providers that wraps the application with the SessionProvider from next-auth/reactThe SessionProvider is essential for the authentication system to work properly, as it makes the session data available throughout the application via the useSession hook. Without it, components that use useSession (like our settings page and authentication-protected routes) would throw errors.
Now the application should deploy successfully, with the authentication system working as expected.
