This is a starter template for building AI agents usingLangGraph andCopilotKit. It provides a modern Next.js application with an integrated LangGraph agent to be built on top of.

• Node.js 18+
• Python 3.8+
• Poetry 2+
• Any of the following package managers:
  • pnpm (recommended)
  • npm
  • yarn
  • bun
• OpenAI API Key (for the LangGraph agent)

Note: This repository ignores lock files (package-lock.json, yarn.lock, pnpm-lock.yaml, bun.lockb) to avoid conflicts between different package managers. Each developer should generate their own lock file using their preferred package manager. After that, make sure to delete it from the .gitignore.

1. Install dependencies using your preferred package manager:

# Using pnpm (recommended)pnpm install# Using npmnpm install# Using yarnyarn install# Using bunbun install

2. Install Python dependencies for the LangGraph agent:

# Using pnpmpnpm install:agent# Using npmnpm run install:agent# Using yarnyarn install:agent# Using bunbun run install:agent

3. Set up your OpenAI API key:

echo'OPENAI_API_KEY=your-openai-api-key-here'> agent/.env

4. Start the development server:

# Using pnpmpnpm dev# Using npmnpm run dev# Using yarnyarn dev# Using bunbun run dev

This will start both the UI and agent servers concurrently.

The following scripts can also be run using your preferred package manager:

• dev - Starts both UI and agent servers in development mode
• dev:debug - Starts development servers with debug logging enabled
• dev:ui - Starts only the Next.js UI server
• dev:agent - Starts only the LangGraph agent server
• build - Builds the Next.js application for production
• start - Starts the production server
• lint - Runs ESLint for code linting
• install:agent - Installs Python dependencies for the agent

The main UI component is insrc/app/page.tsx. You can:

• Modify the theme colors and styling
• Add new frontend actions
• Customize the CopilotKit sidebar appearance

• LangGraph Documentation - Learn more about LangGraph and its features
• CopilotKit Documentation - Explore CopilotKit's capabilities
• Next.js Documentation - Learn about Next.js features and API
• YFinance Documentation - Financial data tools

Feel free to submit issues and enhancement requests! This starter is designed to be easily extensible.

If you see "I'm having trouble connecting to my tools", make sure:

1. The LangGraph agent is running on port 8000
2. Your OpenAI API key is set correctly
3. Both servers started successfully
