How to Implement a LangGraph (LangChainJS) in TypeScript (in 5 minutes)

The ability to create stateful, multi-actor applications is crucial for developing complex systems that can handle a variety of tasks. LANGCHAIN LangGraph is a library designed for this purpose, allowing developers to build applications with Large Language Models (LLMs) by modeling steps as edges and nodes in a graph. In this article, we will explore how to implement a LANGCHAIN LangGraph in TypeScript, complete with code examples and a custom tool that we will invent.
