# Built-in Agent (TanStack AI) Showcase
|
|
|
|
**CopilotKit's `BuiltInAgent` in factory mode with TanStack AI as the LLM backend.**
|
|
|
|
The agent runs **in-process inside the Next.js API route** — there is no separate agent server process to start (unlike the LangGraph TypeScript variant which spawns `langgraph-cli` on port 8123).
|
|
|
|
## Quick Start
|
|
|
|
### Prerequisites
|
|
|
|
- Node.js 18+
|
|
- An OpenAI API key
|
|
|
|
### Setup
|
|
|
|
1. **Clone & install dependencies**
|
|
|
|
```bash
|
|
npm install
|
|
```
|
|
|
|
2. **Set environment variables**
|
|
|
|
Create a `.env.local` file from `.env.example`:
|
|
|
|
```bash
|
|
cp .env.example .env.local
|
|
```
|
|
|
|
Then fill in your `OPENAI_API_KEY`:
|
|
|
|
```
|
|
OPENAI_API_KEY=sk-...
|
|
NEXT_PUBLIC_COPILOTKIT_AGENT=default
|
|
```
|
|
|
|
3. **Start the dev server**
|
|
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
Open [http://localhost:3000](http://localhost:3000) to see the demo index.
|
|
|
|
## Build
|
|
|
|
```bash
|
|
npm run build
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- **Agent Factory**: See `src/lib/factory/tanstack-factory.ts` for the `BuiltInAgent` wiring and TanStack AI integration.
|
|
- **Tools**: Defined in:
|
|
- `src/lib/factory/state-tools.ts` — state management tools
|
|
- `src/lib/factory/server-tools.ts` — server-side tools
|
|
- `src/lib/factory/subagent-tools.ts` — sub-agent tools
|
|
- **API Route**: `src/app/api/copilotkit/[[...slug]]/route.ts` handles the AG-UI protocol.
|
|
|
|
## Next Steps
|
|
|
|
Phase 3+ will add individual demo pages under `src/app/demos/`.
