Getting Started with LangChain
In this chapter, we’re going to look at LangChain and how this framework enables users to build complex LLM applications. You’ll gain an understanding of LangChain and the problems it fixes, as well as an introduction to the core components of LangChain, LangChain Expression Language, and the different types of chains that you can create.
At its core, LangChain is an open-source development framework designed for building LLM applications. By the end of this chapter, you’ll be well-equipped to engineer LangChain applications and use the more advanced functions and capabilities covered in the next chapter.
In this chapter, we’ll cover the following key areas:
- Introduction to LangChain
- Core components of LangChain
- Understanding LangChain Expression Language
- Creating different LangChain chains
This chapter aims to be an introduction to the core concepts to give you a solid base for mastering LangChain...
