# CopilotKit <> LangGraph Starter
|
|
|
|
This is a starter template for building AI agents using [LangGraph](https://www.langchain.com/langgraph) and [CopilotKit](https://copilotkit.ai). It provides a modern Next.js application with an integrated LangGraph agent to be built on top of.
|
|
|
|
## Prerequisites
|
|
|
|
- Node.js 18+
|
|
- Python 3.8+
|
|
- Any of the following package managers:
|
|
- [pnpm](https://pnpm.io/installation) (recommended)
|
|
- npm
|
|
- [yarn](https://classic.yarnpkg.com/lang/en/docs/install/#mac-stable)
|
|
- [bun](https://bun.sh/)
|
|
- Anthropic 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.
|
|
|
|
## Getting Started
|
|
|
|
1. Install dependencies using your preferred package manager:
|
|
```bash
|
|
# Using pnpm (recommended)
|
|
pnpm install
|
|
|
|
# Using npm
|
|
npm install
|
|
|
|
# Using yarn
|
|
yarn install
|
|
|
|
# Using bun
|
|
bun install
|
|
```
|
|
|
|
> **Note:** Installing the package dependencies will also install the agent's python dependencies via the `install:agent` script.
|
|
|
|
|
|
2. Set up your Anthropic API key:
|
|
```bash
|
|
echo 'ANTHROPIC_API_KEY=your-anthropic-api-key-here' > agent/.env
|
|
```
|
|
|
|
3. Start the development server:
|
|
```bash
|
|
# Using pnpm
|
|
pnpm dev
|
|
|
|
# Using npm
|
|
npm run dev
|
|
|
|
# Using yarn
|
|
yarn dev
|
|
|
|
# Using bun
|
|
bun run dev
|
|
```
|
|
|
|
This will start both the UI and agent servers concurrently.
|
|
|
|
## Available Scripts
|
|
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
|
|
|
|

### Agent Connection Issues
|
|
If you see "I'm having trouble connecting to my tools", make sure:
|
|
1. The LangGraph agent is running on port 8000
|
|
2. Your Anthropic API key is set correctly
|
|
3. Both servers started successfully
|
|
|
|
### Python Dependencies
|
|
If you encounter Python import errors:
|
|
```bash
|
|
npm install:agent
|
|
``` |
