Tutorials (original) (raw)

Welcome to the LangGraph.js Tutorials! These notebooks introduce LangGraph through building various language agents and applications.

Quick Start¶

Learn the basics of LangGraph through a comprehensive quick start in which you will build an agent from scratch.

• Quick Start
• Common Workflows: Overview of the most common workflows using LLMs implemented with LangGraph.
• LangGraph Cloud Quick Start: In this tutorial, you will build and deploy an agent to LangGraph Cloud.

Use cases¶

Learn from example implementations of graphs designed for specific scenarios and that implement common design patterns.

Chatbots¶

• Customer support with a small model

RAG¶

• Agentic RAG
• Corrective RAG
• Self-RAG

Multi-Agent Systems¶

• Collaboration: Enabling two agents to collaborate on a task
• Supervision: Using an LLM to orchestrate and delegate to individual agents
• Hierarchical Teams: Orchestrating nested teams of agents to solve problems

Planning Agents¶

• Plan-and-Execute: Implementing a basic planning and execution agent

Reflection & Critique¶

• Basic Reflection: Prompting the agent to reflect on and revise its outputs
• Rewoo: Reducing re-planning by saving observations as variables

Evaluation¶

• Agent-based: Evaluate chatbots via simulated user interactions
