Since LangChain.js is built on TypeScript, leveraging its full potential might be challenging without proficiency in this language. - - In scenarios requiring minimal dependencies where a lightweight setup is necessary. LangChain.js relies on specific installation methods and may not fit environments that restrict the use of package - managers like npm or yarn ## Common questions ### What is the difference between langchain-streamlit-template and langchainjs? langchain-streamlit-template: Template for deploying a LangGraph agent on Streamlit. langchainjs: The agent engineering platform.
