Oops! Something went wrong! :(

ESLint: 8.57.1

ESLint couldn't find the plugin "eslint-plugin-prettier".

(The package "eslint-plugin-prettier" was not found when loaded as a Node module from the directory "/backend".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

npm install eslint-plugin-prettier@latest --save-dev

The plugin "eslint-plugin-prettier" was referenced from the config file in "backend/.eslintrc.js".

If you still can't figure out the problem, please stop by https://eslint.org/chat/help to chat with the team.

Walkthrough

This pull request introduces significant changes to the chat and model provider functionality across multiple files in the backend and LLM server. The modifications primarily focus on restructuring how messages are handled, changing the storage of chat messages from a relational model to a JSON-based approach, and updating the interfaces for message processing. The changes involve updating message roles, simplifying message input handling, and modifying how chats and messages are managed in the system.

🐰 A rabbit's tale of code so bright,
Messages dancing with new might,
JSON columns replace the old,
Chat service refactored, brave and bold!
Hop along the coding trail,
Efficiency without a fail! 🚀

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
