langgraphjs

LangGraph.js is a JavaScript framework for building resilient, stateful language agents as directed graphs, enabling developers to orchestrate complex AI workflows with loops, branching, and human-in-the-loop control. It is designed for AI/ML engineers and Node.js developers who need to create reliable, multi-step agentic systems beyond simple chain-of-thought. Its interesting because it brings production-grade control and fault tolerance to agent orchestration, making it easier to build and debug sophisticated, long-running AI applications.
