LangChain V1 Experimental Repository Share: Practical Guide to RAG, Agent, and Workflow

Recently, a developer shared their experience organizing the LangChain V1 experimental repository. During their research, the author discovered mismatches between the documentation and older tutorials, encountering numerous pitfalls. As a result, they compiled a minimum viable example featuring core components such as RAG (Retrieval-Augmented Generation), Agent tool calling, and Workflow multi-step processing. The repository also includes a FastAPI backend skeleton, environment scripts, and ready-to-run demos, designed to help developers get started quickly and save time. The project remains streamlined, avoiding complex frameworks to ensure users can run it directly without worrying about compatibility issues. For developers currently using LangChain V1, this is a practical open-source project that provides complete demonstrations and code examples, worthy of in-depth exploration and learning.
