First you need to install core module right?

[NarHakobyan]

just checked docs and found out it suggest to install community lib but it must be @langchain/core right?

langchainjs/docs/core_docs/docs/expression_language/get_started.mdx

Line 27 in fec52de

npm install @langchain/openai @langchain/community

Hi @NarHakobyan! I'm Dosu, a friendly bot here to assist you with your coding queries, issues, and contributions while the human maintainers are away. I'm here to make your experience with langchainjs smoother. Let's dive into your issue together!

Yes, you're correct. The core module of LangChainJS is indeed "@langchain/core". This module provides the main functionalities of the LangChain framework, such as handling documents. This is indicated by the line export { type DocumentInput, Document } from "@langchain/core/documents"; in the langchain/src/document.ts file.

The documentation you've pointed out seems to be outdated or incorrect. It should indeed suggest installing "@langchain/core" for the core functionalities. I recommend following the import statements in the codebase for the most accurate information.

If you have further questions or need more clarification, feel free to ask.
