Agentic Chat Example Server

Follow these steps to run the LangGraph agent backend that powers the Agentic Chat example. Commands assume you are in the monorepo root unless noted.

1. Build the Monorepo Packages

From the TypeScript workspace root (AG-Kit/typescript-sdk):

• pnpm install
• pnpm run build

2. Prepare Server Environment Variables

In this directory (AG-Kit/typescript-sdk/packages/examples/agents/server):

• Copy .env.example to .env (or create .env manually)
• Set the required variables:
  • OPENAI_API_KEY
  • OPENAI_MODEL
  • OPENAI_BASE_URL

3. Install, Build, and Start the Server

Still inside AG-Kit/typescript-sdk/packages/examples/agents/server, run:

• pnpm install
• pnpm run build
• pnpm run start

The server exposes endpoints under /v1/aibot/bots/ that the web frontend consumes.

Docker Deployment

Prerequisites

Before building the Docker image, ensure you have:

1. Built the entire monorepo locally

   # From the typescript-sdk root directory
   cd ../../../
   pnpm install
   pnpm build

2. Prepared Environment Variables

   # Copy and configure environment variables
   cp .env.example .env
   # Edit .env and set your OPENAI_API_KEY

Building and Running with Docker

1. Build the Docker Image

   # From the server directory
   docker build -t ag-kit-server .

2. Run the Container

   # Run with environment variables
   docker run -p 9000:9000 \
     -e OPENAI_API_KEY=your_api_key_here \
     -e NODE_ENV=production \
     ag-kit-server
      
   # Or run with .env file
   docker run -p 9000:9000 --env-file .env ag-kit-server

3. Access the Server

   • Server will be available at http://localhost:9000
   • Health check endpoint: http://localhost:9000/health

Docker Features

• Workspace Support: Includes all workspace dependencies in the image
• Pre-built: All dependencies and built files are included
• Performance: Alpine Linux base image for smaller size
• Simple: No build process required in container
