UIGen

AI-powered React component generator with live preview.

Prerequisites

• Node.js 18+
• npm

Setup

1. Optional Edit .env and add your Anthropic API key:

ANTHROPIC_API_KEY=your-api-key-here

The project will run without an API key. Rather than using a LLM to generate components, static code will be returned instead.

2. Install dependencies and initialize database

npm run setup

This command will:

• Install all dependencies
• Generate Prisma client
• Run database migrations

Running the Application

Development

npm run dev

Open http://localhost:3000

Usage

1. Sign up or continue as anonymous user
2. Describe the React component you want to create in the chat
3. View generated components in real-time preview
4. Switch to Code view to see and edit the generated files
5. Continue iterating with the AI to refine your components
