Learn how to build powerful AI workflows using LangChain Expression Language (LCEL).
In this video, I explain:
* What LCEL is in LangChain
* How the | pipe operator works
* Simple chains
* Sequential chains
* Parallel chains
* Data flow between chains
* Common mistakes like missing prompt variables
* Real code examples with modern LangChain
This video is part 1 of a complete LangChain Chains series.In upcoming videos, we’ll cover:
* Router chains
* Conditional chains
* Branching workflows
* Agents
* RAG pipelines
* Tool calling
* LangGraph workflows
* Production-grade AI orchestration
Perfect for:
* AI Engineers
* Backend Developers
* Python Developers
* GenAI Beginners
* LangChain Learners
