# CopilotKit Chat Playground
|
|
|
|
A visual playground for customizing CopilotKit chat components. Adjust colors, fonts, and text, then export production-ready code.
|
|
|
|
|
|
|
|
## Overview
|
|
|
|
This tool lets you customize CopilotKit chat appearance with a live preview and export the code when you're done. Useful for designers and developers who want to integrate AI chat into their applications.
|
|
|
|
## Getting Started
|
|
|
|
### Prerequisites
|
|
|
|
- Node.js 18+
|
|
- npm, pnpm, yarn, or bun
|
|
- OpenAI API key (for the live preview agent)
|
|
|
|
### Installation
|
|
|
|
```bash
|
|
npm install
|
|
```
|
|
|
|
The postinstall script sets up the Python agent automatically.
|
|
|
|
### Running Locally
|
|
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
This starts the UI on `localhost:3000` and the agent on `localhost:8123`. Open your browser to `http://localhost:3000`.
|
|
|
|
## How It Works
|
|
|
|
1. Adjust settings in the left panel (colors, fonts, text, spacing)
|
|
2. See changes in real-time in the center preview
|
|
3. Click "Export Code" when finished
|
|
4. Copy the generated files into your project
|
|
|
|
The export includes:
|
|
|
|
- `MyChat.tsx` - Your customized chat component
|
|
- `layout.tsx` - CopilotKit wrapper
|
|
- `route.ts` - API route
|
|
- `.env.local` - Environment variables template
|
|
|
|
## Available Scripts
|
|
|
|
- `npm run dev` - Start UI and agent
|
|
- `npm run dev:ui` - Start UI only
|
|
- `npm run dev:agent` - Start agent only
|
|
- `npm run build` - Build for production
|
|
- `npm run start` - Run production build
|
|
|

## Troubleshooting
|
|
|
|
### Preview not loading
|
|
|
|
The preview needs the agent running. Check:
|
|
|
|
- Agent is running on port 8123
|
|
- OpenAI API key is set in `agent/.env`
|
|
- No console errors in browser
|
|
|
|
### Agent won't start
|
|
|
|
Reinstall Python dependencies:
|
|
|
|
```bash
|
|
cd agent
|
|
rm -rf .venv
|
|
python3 -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
### Module not found
|
|
|
|
Reinstall node dependencies:
|
|
|
|
```bash
|
|
rm -rf node_modules package-lock.json
|
|
npm install
|
|
```
|
|
|
|
### Port in use
|
|
|
|
Kill the process or use a different port:
|
|
|
|
```bash
|
|
lsof -ti:3000 | xargs kill
|
|
# or
|
|
PORT=3001 npm run dev:ui
|
|
```
