PR Main Files Walkthrough:

apps/yggdrasil-discord-client/src/app/discord-bot/discord-bot.service.ts: The message handling logic has been significantly refactored. The new implementation uses RxJS operators to process the incoming messages in a more streamlined and efficient manner. It also includes additional checks and conditions to handle different types of messages and attachments.
apps/yggdrasil-core-engine/src/app/controllers/chatgpt/chatgpt.controller.ts: The ChatGPTController has been updated to remove the use of ServerUnaryCall and Metadata parameters in the methods. The AuthGuard decorator has been moved to the class level, applying it to all methods in the controller.
libs/nest-langchain/src/lib/nest-langchain.module.ts: This is a new file that introduces the NestLangChainModule. This module provides the NestLangchainService and includes methods for registering asynchronous providers. It is part of the integration of LangChain into the service.

PR Feedback

• General suggestions: The PR seems to be well-structured and follows good coding practices. However, it lacks tests for the new functionality. It is recommended to add tests to ensure the new integration works as expected and does not break any existing functionality.

• 🤖 Code feedback:

  • relevant file: apps/yggdrasil-discord-client/src/app/discord-bot/discord-bot.service.ts
    suggestion: The messageCreateListenerObservers function is quite long and does a lot of things. Consider breaking it down into smaller, more manageable functions. This will improve readability and maintainability of the code. [important]
    relevant line: private messageCreateListenerObservers(message: Message) {

  • relevant file: apps/yggdrasil-core-engine/src/app/controllers/chatgpt/chatgpt.controller.ts
    suggestion: The @UseGuards(AuthGuard) decorator has been removed in the new code. If this was intentional and the routes do not require authentication anymore, then it's fine. However, if authentication is still required, the decorator should be added back. [important]
