Scrimba interactive guides
Scrimba is a code-learning platform that allows you to interactively edit and run code while watching a video walkthrough.
We've partnered with Scrimba on course materials (called "scrims") that teach the fundamentals of building with LangChain.js - check them out below, and check back for more as they become available!
An full end-to-end course that walks through how to build a chatbot that can answer questions about a provided document. A great introduction to LangChain and a great first project for learning how to use LangChain Expression Language primitives to perform retrieval!
LangChain Expression Language (LCEL)
- The basics (PromptTemplate + LLM)
- Adding an output parser
- Attaching function calls to a model
- Composing multiple chains
- Retrieval chains
- Conversational retrieval chains ("Chat with Docs")
