What is LangGraphJS API?
LangGraphJS API provides a programmatic interface to design AI agent workflows using directed graphs. Each node in the graph represents an LLM call, decision logic, or data transformation. Developers can chain nodes, handle branching logic, and manage asynchronous execution seamlessly. With TypeScript definitions and built-in integrations for popular LLM providers, it streamlines development of conversational agents, data extraction pipelines, and complex multi-step processes without boilerplate code.
Who will use LangGraphJS API?
- JavaScript/TypeScript developers
- AI/ML engineers
- Data scientists
- Full-stack developers
- Technical architects
How to use the LangGraphJS API?
- Step1: Install via npm or yarn (npm install langgraphjs-api).
- Step2: Import and configure your LLM provider credentials.
- Step3: Define nodes representing model calls, decisions, or transforms.
- Step4: Connect nodes into a directed graph to represent workflow.
- Step5: Execute the graph and handle results or errors asynchronously.
- Step6: Monitor and log node outputs for debugging and optimization.
