What would you like to be added:
The current backend is structured using NestJS, and there is a proposal to migrate it to Go. The primary reason for this migration is to engage contributors who have a stronger interest in backend development.

The migration should take into account the following considerations:

• Implement LangChain functionality in the Go environment.
• Utilize OAuth for user authentication and authorization.
• Ensure proper validation mechanisms are in place.
• Verify that the new backend operations are consistent with the existing functionality.
• Generate Swagger documentation for the API in the new setup.

Why is this needed:
Migrating to Go may enhance our ability to attract backend-focused contributors and improve the overall performance and scalability of our application. This transition also aims to maintain functionality while leveraging Go's efficiency and capabilities.
