Summary of Changes

Hello @morningstarxcdcode, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a comprehensive backend infrastructure for a new application, 'LocalMind'. It sets up a Node.js/Express/TypeScript project with MongoDB integration, robust user authentication including API key generation, and flexible AI model management. The system is designed to integrate with various AI providers like Ollama, Google Gemini, and Groq, allowing users to configure and interact with these models. Additionally, it includes features for processing datasets and a new utility for standardized error message extraction. The scope of changes is significantly broader than indicated by the PR title, effectively initializing a full-fledged backend service.

Highlights

• Full Backend Initialization: Establishes a complete Node.js, Express, and TypeScript backend project, including configuration files, build scripts, and development tools.
• User Authentication System: Implements user registration, login, profile management, and secure API key generation using JWT for authentication and Argon2 for password hashing.
• Multi-AI Model Integration: Provides modules for interacting with various AI services, specifically Google Gemini, Groq, and local Ollama instances, enabling diverse AI capabilities.
• Dynamic AI Model Configuration: Introduces a system for users to configure and manage their preferred AI agents (providers, models, keys) and system prompts, stored in a MongoDB database.
• Dataset Processing: Adds functionality to upload and process datasets (e.g., CSV files) using AI models for extraction and validation, leveraging Langchain document loaders.
• Standardized Error Handling: Implements a getErrorMessage utility to safely extract error messages from unknown error types, improving error reporting and robustness across the application.

Code Review

This pull request introduces a substantial amount of new code, essentially setting up an entire backend application. The title "chore(error-handling): add getErrorMessage util and use it in Ollama" does not reflect the scope of these changes. While the new error handling utility is a good addition, the PR includes multiple new features like user authentication, AI model configuration, and dataset processing. In the future, it would be highly beneficial to break down such large changes into smaller, more focused pull requests. This makes the review process more manageable and allows for more detailed feedback. My review focuses on architectural patterns, correctness, and potential bugs I've identified across the new modules.
