langchain in action
Basic Information
This repository is the companion codebase for a Chinese-language practical course on LangChain offered via Geekbang. It provides concise, example-driven demonstrations and explanations of several early LangChain framework modules and design patterns. The material is pedagogical, intended to help learners understand core concepts and see runnable sample code that illustrates module-level usage. The README explicitly notes that LangChain evolves quickly and that some examples may require newer library versions or adjustments. The repo also references a paid course and an accompanying book to support deeper study and is aimed at developers and practitioners seeking a focused, classroom-style introduction to LangChain internals.

App Details
Features
Direct, focused code examples that illustrate key LangChain modules and common patterns. Clear explanatory text and image assets oriented toward learners. Chinese-language instructional framing with links pointing to the related paid Geekbang course and an accompanying book. Pedagogical organization designed to follow lesson content rather than provide production-ready applications. Emphasis on early LangChain designs so users may need to update dependencies to run examples with current LangChain releases. Lightweight repository intended as teaching material and a conceptual reference for module behavior and usage.
Use Cases
Helps learners rapidly grasp LangChain concepts through short, concrete examples and accompanying explanations. Acts as a practical reference for architecture and module-level patterns from an earlier stage of LangChain development, useful for experimentation and prototyping. Encourages readers to compare examples with the latest LangChain documentation and to update code where APIs have changed. Provides pointers to a paid course and a book for structured lessons and further reading. Best used by developers who prefer example-driven learning and who will adapt samples to current library versions.
