LANGGRAPH FOR COMPLEX WORKFLOWS

Summary from the TLDR Web Dev newsletter

LangGraph is an LLM workflow orchestration library that helps developers build complex, multi-step automations using graph-based architectures with strong support for parallel processing. It supports structured responses, tool calling, and agent-based workflows that can cycle between LLM invocations and tool executions until completion. Unlike LangChain's DAG-based approach, LangGraph can handle cyclic workflows and parallel execution, making it useful for orchestrating multiple specialized LLM instances or creating automation pipelines that don't necessarily require LLMs at all.
